Servicing The Fluid Section - Titan ADVANTAGE GPX 165 Owner's Manual

mating the Gear Housing and the clutch Housing
1. Place the gear housing assembly onto the cart in front of the
clutch housing. Line up the dowel pins in the gear housing
with their corresponding holes in the clutch housing. Slide
the gear housing assembly onto the clutch housing until there
is no gap between the housings.
2. Thread the four hex screws and lock washers through the
clutch housing and into the gear housing.
3. Using a 1/2" wrench, snug and tighten the hex screws in a
crossing pattern. Torque to 140–155 in./lbs.
4. Using a 9/16" socket, thread the two hex screws that secure
the gear housing to the cart through the underside of the cart
and into the gear housing. Torque to 100–120 in./lbs.
5. Connect the wire from the EPC housing to its mating
connector on the engine wire harness.
6. Make sure that there is a white PTFE o-ring on the end of the
transducer that gets inserted into the filter housing. Insert the
transducer into the filter housing port.
7. Hold the transducer tube with a pliers to prevent it from
rotating, and turn the transducer nut clockwise with a 3/4"
open-end wrench to tighten it into the filter housing. Torque
the nut to 360–400 in./lbs.
checking the clutch Gap
1. Remove the plastic plug from the top of the clutch housing.
Look through the port to locate the clutch armature and the
clutch rotor.
2. Check the gap between the clutch armature and the clutch
rotor using a .016" feeler gauge and a .035" feeler gauge.
a. Insert each feeler gauge through the port and into the gap between
the clutch armature and the clutch rotor. The .016" feeler gauge
should fit in the gap. The .035" feeler gauge should not fit in the gap.
b. Pull the engine pull cord several times to rotate the clutch armature,
checking the gap with each feeler gauge between each pull.
c. If the .016" gauge does not fit or the .035" gauge does fit at any
checkpoint, the gap must be readjusted. This is done by relocating
the clutch hub and armature assembly on the engine shaft. Refer to
the "Removing/Replacing the Clutch Hub and Armature Assembly"
procedure.

Servicing the Fluid Section

Use the following procedures to service the valves and repack the
fluid section.
1. Start the engine (refer to the procedures in the Operation
section of this manual). Turn the pressure control knob
clockwise to its maximum pressure setting.
2. Toggle the pump ON/OFF switch between the ON and OFF
positions in short bursts until the slider assembly stops in a
position where the fluid section connecting pin and retaining
ring are visible through the slot in the slider housing.
3. Turn off the engine and perform the Pressure Relief Procedure.
Before proceeding, follow the Pressure Relief
Procedure outlined previously in this manual.
Additionally, follow all other warnings to reduce the
risk of an injection injury, injury from moving parts or
electric shock.
4. Remove the return hose from the
clamp on the siphon tube. Unscrew
the siphon tube from the inlet valve
housing.
5. Loosen and remove the fluid hose
from the fitting on the back of the
cylinder of the fluid section.
6. Loosen and remove the four front
cover screws. Remove the front
cover.
7. Slide the retaining ring up on the
slider assembly to expose the
connecting pin.
8. Push the connecting pin forward
through the slider assembly and
piston. The connecting pin will fall

out from the rear window of the slider housing where it can
be retrieved.
9. Using a wrench, turn the jam nut
counterclockwise to loosen it from
the pump housing.
10. Turn the fluid section
counterclockwise to remove it from
the pump housing.
11. Place the fluid section cylinder

occur.
12. Loosen and remove the inlet valve
housing from the cylinder.
13. Remove the inlet cage, inlet valve
ball, inlet valve seat, and o-ring from
the inlet valve.
14. Clean out any debris in the inlet
valve housing and examine the
housing and the inlet valve seat. If
the seat is damaged, reverse to the
unused side or replace the seat.
15. Remove the splash guard from the top of the upper seal
retainer.
16. Using a wrench, remove the upper seal retainer.
17. Slide the piston rod out through the bottom of the cylinder.
18. Inspect the piston rod for wear and
replace if necessary.
19. Remove the upper packing assembly
from the top of the cylinder.
20. Remove the lower support ring and
lower packing assembly from the
bottom of the cylinder.
NOTE: Be careful not to scratch,
score, or otherwise damage
the cylinder during removal
of the packing assemblies.
21. Remove the cylinder from the vise.
22. Insert the connection pin through
the hole at the top of the piston
rod and clamp each end of the
connecting pin in the vise. This will
hold the piston rod in position for
disassembly.
NOTE: Do not clamp the piston rod
directly in the vise. Damage
to the piston rod will occur.
23. Using a 3/8" hex wrench, loosen and
remove the outlet valve retainer
from the piston rod.
24. Remove the outlet valve seal, outlet
cage, outlet valve ball, nylon washer,
and outlet valve seat from the outlet
valve retainer.
25. Clean out any debris and examine
the retainer and outlet valve seat. If
