Great Plains Manufacturing, Inc. Table of Contents Index 1Important Safety Information
PTO-Specific Hazards
Even if you are experienced in PTO operations, review
the “Using PTO Safely” topic on page 2. Topics in this
manual dealing with PTO hazards include this PTO alert
symbol and the standard alert symbol below.
PTO hazards include:
▲ Entanglement:
resulting in abrasions, lacerations, crushing,
dismemberment or death. Loose clothing, cuffs, frays, laces,
coattails, drawstrings, hair or scarves are taken up by a
PTO faster than you can react, and with overpowering
torque.
▲ Flailing machinery:
resulting from an unsecured torque arm, resulting in serious
injury or death.
▲ High pressure fluid sprays:
due to hydraulic hose failure, resulting from PTO shaft
over-speed or damaged hoses.
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.2014-06-16 Table of Contents Index 401-885M
2 Single-Section PTO Pumps Table of Contents Index Great Plains Manufacturing, Inc.Using PTO Safely
The accessories covered by this manual rely on PTO power to
operate, and require an adjustment at the planter while the
PTO is running. The PTO pump is designed to work on a stub
shaft PTO, and leaves no exposed shaft in use.
▲ Use only a tractor with an approved master shield for the
PTO.
▲ Use all guards provided for the tractor PTO. Have minimal
or NO shaft exposed after connecting the PTO pump.
▲ Use only a rear-facing PTO. The provided hoses and torque
arms are not designed for use with a tractor-front or
tractor-side PTO.
▲ Use only the correct (540 or 1000) rpm PTO, or an
adjustable PTO set to the correct rpm (maximum).
Running at a higher speed could result in equipment failure,
and serious injury.
▲ Use only a PTO with the correct shaft, and for 1000 rpm,
matching Great Plains coupler:
13⁄8 inch (35 mm) 6-spline
13⁄4 inch (44.5 mm) 20-spline and 826-777C coupler
13⁄8 inch (35 mm) 21-spline and 826-778C coupler
▲ Do not use any other adaptor, coupler, driveline, extender
or external gearbox.
▲ Use only a “live” or “independent” PTO. If the PTO only
operates when the tractor is in motion, there is no safe way
to set the fan speed.
▲ Ensure that all involved personnel are trained on PTO
operations and hazards. Always know where all team
members are before, during and after PTO operations.
▲ Allow only essential personnel near the PTO during setup,
adjustment, operation and disconnection.
▲ Prior to PTO setup, remove any stray wire, rope or twine
found nearby. Should a loose end encounter the PTO stub, it
is taken up at up to 14 feet per second, and could wrap
around someone and pull them in.
▲ Wear only snug-fitting clothes, with no scarves, loose
strings, cords, ties, and no frays, when working near a PTO.
▲ Tie long hair back or gather it up under a well-secured hat.
▲ Shut the tractor off for PTO connections or disconnections.
Do not trust your life to clutches and throw-outs.
▲ A PTO shaft is a hazard at any speed, even when well below
rated shaft rpm, coasting to a stop, or idling.
▲ Never step on or over the master shield or installed PTO
pump.
▲ Be extra vigilant if any tractor PTO controls are external,
and in proximity to the PTO.
▲ Elevate pump hose slack so that ground contact is not
possible during transport or field operations.
▲ Keep all PTO safety decals clean and legible. Replace any
that are faded or damaged.

6 Single-Section PTO Pumps Table of Contents Index Great Plains Manufacturing, Inc.Introduction
Description of Unit
One of 17 dealer- or field-installed kits convert the
hydraulic fan power source from tractor hydraulic remote
to tractor Power Take-Off (PTO). An additional kit
updates older fan motors for PTO compatibility.
Refer to Figure 1
Each Single-Section PTO Pumps kit includes:
• a flow control valve assembly for setting fan rpm,
• a tethered 540 or 1000 rpm PTO pump , with torque
arm and safety chain (no gearbox is required; a
coupler is required for the 1000 rpm pump),
• an oil reservoir , with sight gauge, line filter and
6.5 gallon capacity (5.5 gallons/21 liters, used),
• an oil cooler , mounted inside the fan, and;
• all interconnecting hoses (not shown).
There are separate kits for rigid and rotating planters,
pull-type and 3-point planters, planters with and without
fertilizer capability and ground drive vs. hydraulic drive.
Suitable Applications
A PTO kit may be needed where:
• the tractor has an Open Center hydraulic system;
• the tractor has no remote port for the fan; or,
• the tractor is Closed Center, but the remotes offer
insufficient oil flow to reliably operate the fan.
Kits Covered
See “Compatible Planters” starting on page 25 for more
details. Kits for 2- and 3-section planters are covered in
separate manual 411-015M.

Great Plains Manufacturing, Inc. Table of Contents Index PTO Operation 11Hitching with PTO
Hitching procedures are different for 540 rpm pumps
(below) and 1000 rpm pumps (page 12).
Hitching with 540 rpm PTO
The pump may be installed before or after hitching the
planter to the tractor. With a 3-point planter, installing the
pump first may be easier.
Prepare Tractor
1. Back the tractor into close proximity to the planter
(within pump hose reach of the PTO shaft).
2. Shut down the tractor and remove the key.
Entanglement and Crushing Hazard:
Never perform any mechanical adjustment, PTO setup or
hitching with the tractor running. Take no chances that the
PTO might become active. Entanglement or flailing equipment
can cause serious injury or death faster than you can react.
Refer to Figure 7
3. Make any necessary adjustment to the tractor
drawbar . This might include:
inverting an offset drawbar, and/or
relocating a clevis assembly (not shown).
Entanglement and Flailing Equipment Hazards:
Do not use a driveline, shaft extension, adaptor or external
gearbox with the PTO pump. Use only a native 540 rpm
6-spline stub shaft. Extra fittings create entanglement hazards.
Fittings also destabilize the shaft, and may make it impossible
to adequately secure the pump against torque and shaft slip.
Mount Pump
4. Clear the PTO shaft of any pins or wires that
might prevent the pump from fully seating on the
shaft.
5. With hydraulic hoses to rear, and torque arm to
right of drawbar, slide the pump assembly fully onto
the PTO shaft.
Secure Pump
Refer to Figure 8 (shown with pump off for clarity)
6. With the torque arm firmly against the drawbar:
loop the chain once around the drawbar,
then through the anchor point ,
then around the drawbar at least once more,
then through the keyhole slot in the torque plate.
The drawbar loops prevent pump rotation.
The anchor loop retains the pump on the PTO shaft.

12 Single-Section PTO Pumps Table of Contents Index Great Plains Manufacturing, Inc.Refer to Figure 9
7. At least one full chain link must be exposed at the
slot on the decal side of the torque arm plate.
If there are more than a few chain loops left at the
plate keyhole, route any excess chain through the
anchor point and/or around the drawbar.
8. Do NOT use any pins, cross-bolts or wires to secure
the pump to the PTO shaft. Such fasteners are not
required for safe pump operation, and would add a
needless entanglement hazard.
9. Pull and twist the pump assembly to verify that the
chain is sufficiently taut to prevent excess pump
rotation or sliding along the PTO shaft.
10. Complete normal planter hitching.
Hitching with 1000 rpm PTO
540 rpm hitching begins on page 11.
The 1000 rpm pump may be installed before or after
hitching the planter to the tractor.
Install Coupler
The 1000 rpm PTO kits require one of two
tractor-specific couplers, not included with the PTO kit:
826-777C 1 3/4-20 PTO COUPLER
826-778C 1 3/8-21 PTO COUPLER
Refer to Figure 10 (showing coupler 826-778C)
1. Loosen both set screws ( and ) at the narrow
end of the coupler. Note that they are different sizes.
2. Rotate the coupler until the internal keyway aligns
with the key on the pump shaft. Slide the coupler
onto the pump shaft.
3. Tighten both set screws to the Grade 5 torque
specification for each thread size.
To remove or exchange a coupler at a later time, first
dismount the pump assembly from the tractor PTO shaft,
then loosen both set screws.

counter-sunk clamping holes in the aft end of the
coupler. The screw head fully seat, below the
surface of the coupler, in these holes.
See NOTICE at right.
12. Adjust the position of the coupler on the shaft until
the screw threads are in the shaft groove . Thread
screw in until finger tight.
13. Insert the other socket head cap screw in the other
side of the coupler. Thread it until finger tight.
14. Pull and twist the pump assembly to verify that both
retention screws have engaged the PTO shaft grove
and prevent the pump from sliding along the PTO
shaft.

Entanglement and Flailing Equipment Hazards:
Do not use a driveline, shaft extension, adaptor or external
gearbox with the PTO pump. Use the pump, with a Great
Plains coupler, only on a native 1000 rpm 20- or 21-spline
stub shaft. Extra fittings create entanglement hazards. Fittings
also destabilize the shaft, and may make it impossible to
adequately secure the pump against torque and shaft slip.
Equipment Damage Risk:
Use the clamping holes . Do not use the drive-out holes
(the smaller forward holes that are threaded to the surface).
Drive-out holes are used only during dismount. The screws
only partially thread into these holes. These holes do not
adequately secure the pump to the shaft. The screws are likely
to fall out if these holes are used for pump mounting.

14 Single-Section PTO Pumps Table of Contents Index Great Plains Manufacturing, Inc.Check Hydraulics
Check Oil Level
Refer to Figure 12
1. Verify that the planter is level front to back and side
to side.
2. Inspect the sight gauge on the pump system
reservoir tank. The oil level must be aligned with
the center border of the OIL FILL LINE decal
(858-003C).
Hot Surface and Hot Fluid Hazards:
Assess the tank temperature before adjusting oil level.
Draining excess hot oil could result in a severe burn. If the
PTO has been operated recently, the oil temperature could be
as high as 180°F (82°C).
3. Add or drain oil as needed to obtain the correct
amount. Some adjustment is normally required with
a new system, or after a filter change.
Note: The fill level dimension from tank bottom is:
9.15 inches (23.2 cm)
If the 858-003C decal requires replacement, adjust
the center border line to this height.
Inspect Hoses and Fittings
4. Check that all hydraulic fittings are tight and dry.
Inspect all hoses for damage, wear and fatigue.
Because the PTO pump system is closed, any
visible fluid may be an indication of a leak.

Great Plains Manufacturing, Inc. Table of Contents Index PTO Operation 15Starting the Pump
While the planter is stationary, it may be necessary to
briefly operate the pump for any of several reasons:
• verify system installation or PTO operation.
• verify oil level with system fully charged.
• set initial meter pressurization.
Refer to Figure 13
1. If the system is adjusted, leave the flow control
valve as-is.
If the system is not yet adjusted, close the flow
control valve to prevent fan motion. Turn the lock
disc counter-clockwise to release the knob .
Turn the knob fully clockwise to close the valve.
2. Clear the hitch area of non-essential persons.
Check essential personnel for long hair, scarfs,
cords, frays, loose flaps and anything else that
might get entangled. Clear the area of dangling or
loose wires, straps, cord and other lines that might
become entangled and pull someone in.
3. It is not necessary to run the PTO at the full 540 or
1000 rpm. You may run it any lower speed that
provides sufficient meter pressurization (page 17).
Equipment Damage Risk:
Do not START the pump and fan suddenly at high PTO power.
Engage the PTO clutch slowly (if possible) and/or at low
engine rpm, and gradually increase PTO rpm. The hydraulic
fan can be damaged by sudden acceleration.
4. • Check that tractor is in Park or Neutral.
• Check parking brake set.
• Set the tractor PTO controls for
540 or 1000a rpm gearing (if multi-speed) and
clockwise rotation (if bidirectional).
• Start tractor engine and set throttle to idle.
• Engage the PTO.
• Bring the tractor engine and PTO up to intended
field rpms.
5. Check for hydraulic fluid leaks.
6. Verify fluid level in tank (page 14).
a. Operate above 540 rpm only with a 1000 rpm pump.
1
2
Entanglement and Crushing Hazard:
Use extreme caution in the hitch area when the PTO is
operating.
High Pressure Fluid Hazard:
Watch for signs of fluid leaks. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. Use a piece of paper or cardboard, NOT BODY
PARTS, to check for leaks. Wear protective gloves and safety
glasses or goggles when working with hydraulic systems. If an
accident occurs, seek immediate medical attention from a
physician familiar with this type of injury.

1 22014-06-16 Table of Contents Index 401-885M
16 Single-Section PTO Pumps Table of Contents Index Great Plains Manufacturing, Inc.About the Flow Control Valve
The flow control valve adjusts the percent of PTO pump
output that is supplied to the planter hydraulic motors.
The total pump flow, in gpm or liters/min, is also directly
proportional to PTO shaft rpm.
Adjustment typically requires two persons. Pump oil flow
is ideally adjusted with all motors active under simulated
field workload, relying on Magnehelic® pressure gauge
readout, and in some cases seed monitor rpm readout.
On Great Plains Yield-Pro® single section planters, the
PTO pump supplies one or two hydraulic motors.
The table below summarizes the motor count/use and
readout resource available for the covered planters.

Great Plains Manufacturing, Inc. Table of Contents Index PTO Operation 17Setting Meter Pressurization
General Steps for all Kits
Refer to Figure 15
Meter pressurization is set as for a standard planter,
using the PTO kit valve rather than a lever for a tractor
hydraulic remote. This adjustment is normally made with
the seed meters full of seed.
Consult your planter Seed Rate manual for the correct
seed disk, meter inlet shutter setting, and recommended
initial pressure as reported by the Magnehelic® gauge .
1. Check that the Inlet Butterfly valve handle is set
to 30°. If not, loosen the pivot bolt, reset handle, and
Re-secure bolt.
2. Mount the PTO pump (page 11).
3. Shut off the tractor and remove the key.
4. Consult your planter Seed Rate manual for the
intended crop, noting:
• Range and Transmission sprockets required,
• correct Air-Pro® seed disk (not shown),
• initial inlet shutter setting (not shown), and
• initial meter pressurization.
5. Install seed disks. Leave rain covers off meters.
6. Set meter inlet shutters per the Seed Rate manual.
7. Open any slide gates under hoppers.
8. Load enough seed to completely fill the meter inlet
tubes, and at least partially fill every hopper.
9. Set out containers, under row unit seed tubes, to
collect seed metered during setup.
10. Clear the hitch area of non-essential persons.
Check essential personnel for long hair, scarves,
cords, frays, loose flaps and anything else that
might get entangled. Clear the area of dangling or
loose wires, straps, cord and other lines that might
become entangled and pull someone in.

1. Configure the meter drive system sprockets for the
rate desired (see Seed Rate Manual).
2. Per your planter Operator manual, hitch the planter.
Raise the planter. Install lift locks. This is to free the
meter ground drive wheel.
3. • Check that tractor is in Park or Neutral.
• Check parking brake set.
• Set the tractor PTO controls for
540 or 1000 rpm gearing (if multi-speed) and
clockwise rotation (if bidirectional).
• Start tractor engine and set throttle to idle.
• Engage the PTO.
• Bring the tractor engine and PTO up to intended
field rpms.
4. At the flow control valve, turn the lock disc
counter-clockwise to release the knob . Slowly
turn the knob counter-clockwise to start the fan.
Bring the fan speed up until the Magnehelic® gauge
displays the suggested pressure for this crop.
5. Turn the meter ground drive wheel forward several
turns, until all exposed cells in all seed disks contain
seed.
6. Recheck the Magnehelic® gauge . The reported
pressure is likely to have increased. Adjust the flow
control knob to bring the pressure reading back to
the recommended value. Tighten the lock disc.
7. Shut down the PTO, and as desired, the tractor.
8. Install rain covers on seed meters.
The PTO pump is now ready for field work. Some
adjustment of meter pressure and inlet shutters may be
required, depending on seed and planting conditions.
Use the flow control valve, and not the butterfly valve, to
make pressure adjustments.

1. Have the DICKEY-john® Planter/Drill Control User
Level 2&3 manual at hand. Making changes to the
GROUND SPEED SETUP configuration requires
the Level 2 password.
2. Have the Operator and Seed Rate manuals at hand,
so that meter setting and fan rpm targets are known
for the seed to be planted.
3. Turn the IntelliAg® monitor system on.
Turn the Master switch off.
On the console, navigate to the
GROUND SPEED SETUP screen.
Record the ground speed constant:
4. Set:
5. Hitch the tractor to be used, and install the PTO
pump. Raise the planter.
6. Turn the lock disc counter-clockwise to release
the knob . Turn the knob fully clockwise to shut off
flow to the motors.
7. Start the tractor, and seed monitor. Bring the PTO
up to expected field rpm (which is often not the full
1000 rpm).
8. Turn the IntelliAg® Master switch on to engage the
hydraulic seed meter drive.
9. With one person observing the Magnehelic®
pressure gaugea, turn the knob
counter-clockwise to obtain the pressure
recommended for this planter configuration, crop,
population and intended field speed.
Secure the knob at this setting with the lock disc.
10. Shut down the PTO. Set Master switch off.
11. On the console, navigate to the
GROUND SPEED SETUP screen.
Restore the original settings:

20 Single-Section PTO Pumps Table of Contents Index Great Plains Manufacturing, Inc.PTO Unhitching
The pump may be dismounted before or after unhitching
the planter and tractor. With a 3-point planter,
dismounting the pump last may be easier, which is the
order shown on this page. For safety, have the tractor
completely shut down during PTO dismounting.
1. At the tractor, shut down the PTO.
Note: The PTO may be shut down suddenly or gradually.
The fan circuit includes a bypass to recirculate
excess pressure during deceleration. The fan is
only sensitive to sudden acceleration.
2. Do not approach the hitch area until the PTO shaft,
and the fan, have slowed to a complete stop.
3. Mechanically unhitch the planter per the Operator
manual. Leave the PTO pump mounted at this time.
4. Pull the tractor forward enough to allow access to
the PTO pump. Put the tractor in Park or Neutral.
Engage the parking brake. Shut the tractor down.
Remove the key.
Dismount 540 rpm Pump
Refer to Figure 9 on page 12
5. Pass the free end of the pump chain forward
through the torque arm keyhole.
6. Unwrap the chain from the anchor point and
drawbar.
7. Slide the PTO pump off the PTO shaft. Store the
pump on the planter. Use the chain to secure it to
any available structure.
Dismount 1000 rpm Pump
Refer to Figure 18
5. Loosen and remove the socket head cap screws
at the PTO coupler .
6. Slide the PTO pump off the PTO shaft.
If, after removing the cap screws, the coupler is still
grasping the PTO shaft too tightly to remove, use
the drive-out holes to pry the clamping halves
apart. Insert the cap screws in the forward drive-out
holes. Tighten them alternately until the coupler is
free.

Oil and Filter Change
Oil Fill
Refer to Figure 19 and Figure 20
A dry or fully drained system may require as much as
6.5 gallons (25 liters) of oil to charge the cooler, pump,
motor, hoses, filter and valve, and leave 5.5 gallons
(21 liters) in the reservoir.
Before adding oil, check that the drain plug is secure,
and that there are no signs of leaks in hoses or at any
system fittings.
Oil Specification
10W-30 good quality mineral base hydraulic fluid,
viscosity 70 to 250 SUS at 210°F (100°C).
Remove the filler cap . Add oil until the oil level in the
tank, as observed on the sight gauge , reaches the fill
line on the decal (the horizontal mid-border of the decal).
The fill line is:
9.15 inches (23.2 cm)
above the tank bottom. If the 858-003C decal requires
replacement, adjust the center border line to this height.
Operate the PTO system briefly, or until the tank level
stops changing. See “PTO Operation” on page 8 for
operations.
Recheck the sight gauge. As necessary, add oil to fill
line.
Oil and Filter Change
At a regularly scheduled oil change, also change the
filter. At initial system flush, no filter change is required.
Refer to Figure 19 and Figure 20
1. Wait for the oil to cool before changing the oil.
2. Place a container under the drain plug of the
reservoir, with at least a capacity of:
7 gallons (26 liters)
3. Carefully remove the drain plug.
4. Allow several minutes for oil in the filter to drain into
and out of the reservoir. Change filter as required.
See page 23 for filter size. Seat filter per
instructions on filter.
5. Thread the plug back into the tank. Seating torque
is 27 to 43 foot-pounds (37 to 58 N-m).

Before You Start
Most accidents are the result of negligence and
carelessness, usually caused by failure of the installer to
follow simple but necessary safety precautions. Allow no
one to install the Air-Pro® PTO pump before carefully
reading this manual.
Fasteners may be loosely assembled. Remove them
before mounting the component. Due to evolving
manufacturing practices, sub-assemblies may already be
completely pre-assembled. If so, check that fasteners are
tight, and skip the unneeded assembly steps.
Compatible Planters
One PTO pump kit is always required. Older planters
may also require a fan update kit. Each kit updates one
planter.
Fan Motor Compatibility
The YP425/625/825A/3P Single-Section PTO Pumps
kits require a 2-port fan hydraulic motor (having no case
drain). Older planters, having 3-port fan hydraulic motors
(with a case drain) cannot install a PTO kit unless the fan
is updated.
Check the planter serial number, or inspect the fan.
Planters manufactured with 3-port fans are:
If the planter has a 3-port/case-drain fan motor, order
one fan update kit:

Call-Outs
Pre-Delivery and Other Options
If you are installing the Air-Pro® PTO Pump on a
newly-shipped planter, it may be more convenient to
install the PTO pump system during the pre-delivery
setup:
• Install the PTO pump system after installing the
tongue (pull-type only). The tongue must be in place
for hose re-routing.
• Install the PTO pump system after mounting a fertilizer
sub-frame (option, pull-type only). This sub-frame
must be in place for flow control valve mounting, and in
some cases, reservoir mounting.
• Install the PTO pump system before installing
frame-mounted row options. This improves foot room
and reduces sharp object hazards while working near
tool bars.
• Install the PTO pump system before installing
row-mounted coulters or row cleaners. This improves
foot room and reduces sharp object hazards while
working near tool bars.
• Install the PTO pump system before installing
markers. This eliminates an overhead sharp object
hazard, and improves working space at the
mainframe.
Prepare Planter
1. Read and understand “Important Safety
Information” starting on page 1.
2. Position the planter on a level surface in a well
lighted location suitable for the installation. A clear
surface beneath makes it easier to recover any
dropped parts. If markers are already installed,
choose an area with enough room to unfold them.
3. Configure the planter for Parking, as instructed in
the planter Operator manual.
4. If markers are already installed, unfold them.
5. Unhitch the planter.

If not installing a 401-956A fan motor update, continue at
“Install Fan Cooler” on page 37.
Refer to Figure 33 (shown with fan RH housing transparent)
39. Select one new:
890-396C BUSHING - FAN
The bushing includes three screws:
HHCS #10-24x1 INCH GRADE 8 FULL THREAD
These screws may be loose in a package, or may
be threaded into the drive-out holes of the bushing.
If threaded, remove them.
40. Make sure the surfaces of the bushing cone,
impeller central hole and impeller threaded holes
are free of any anti-seize compounds or other
lubricants.
41. Select one new:
168-094D HYD MOTOR 1/8 KEY
Place the impeller onto the motor shaft .
Place the cone end of the bushing onto the
motor shaft. Rotate the bushing until the bushing
keyway and the motor shaft keyway align. Insert the
key , making the outside end flush with the
bushing face.
Refer to Figure 34
42. Press the bushing firmly into the impeller .
Check that the gap between the bushing flange
and the impeller face is equal around the edge of
the bushing.
Equipment Failure Risk:
Mind the gap . The flange to impeller face gap must not be
closed at any point, and must be as consistent as practical to
ensure proper key capture and minimize impeller run-out
during operation.
43. Place the three screws into the drilled
(clearance) holes of the bushing. Thread them into
the tapped holes of the impeller, until the screw
heads just make contact with the bushing.
44. Using a small hand wrench, tighten the screw
nearest the key to just hand tight.
45. Tighten the remaining two screws alternately to
hand tight.
46. Using a torque wrench, tighten all three screws, in
sequence, one full rotation per screw, until the
specified torque is reached:
60 inch-pounds (5 foot-pounds, 6.7 N-m)
47. Check that the impeller spins freely and without
excessive run-out. If not, re-adjust seating screws
and re-tighten to torque spec.
Equipment Failure Risk:
Do not lose these screws . If any need replacement, use
Grade 8 or higher strength, rated for 60 inch-pounds torque.
Using weaker screws has a high risk of impeller separation
during operation, substantial equipment damage, and some
risk of personal injury.

Modify Fan Cage
Refer to Figure 43
61. Prepare an exit opening in the fan cage for the
cooler hoses. The hole needs to be:
• located at bottom center of the fan cage,
• on the center-line of the MJIC elbow ports,
• wide enough for a 3/4 FJIC hose fitting, about:
11⁄4 inches or 3.2 cm),
• long enough for one hose diameter plus one
3/4 FJIC hose fitting, about
21⁄4 inches or 5.7 cm) total, and

Connector Identification
Refer to Figure 71 (a hypothetical fitting)
Leave any protective caps in place until immediately prior
to making a connection.
NPT - National Pipe Thread
Note tapered threads, no cone/flare, and no O-ring.
Apply liquid pipe sealant for hydraulic applications
(do not use tape sealant, which can foul filters).
JIC - Joint Industry Conference (SAE J514)
Note straight threads and the 37° cone on
“M” fittings (or 37° flare on “F” fittings). Use no
sealants (tape or liquid) on JIC fittings.
ORB - O-ring Boss (SAE J514)
Note straight threads and elastomer O-ring .
Prior to installation, to prevent abrasion during
tightening, lubricate O-ring with clean hydraulic fluid.
Use no sealants (tape or liquid) on JIC fittings.
ORB fittings that need orientation, such as the ell
depicted, also have a washer and jam nut
(“adjustable thread port stud”). Back jam nut away
from washer. Thread fitting into receptacle until
O-ring contacts seat. Unscrew fitting to desired
orientation. Tighten jam nut to torque specification.
