Replacing the Transducer
1. Loosen and remove the four front cover screws. Remove the
front cover.
2. Stop the sprayer at the bottom of its stroke so that the piston
is at its lowest position.
3. 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. Tilt the sprayer back for easy access to the fluid section.
5. Using a 3/8” hex wrench, loosen and remove the two socket
screws.
6. Pull the fluid section down approximately 1/2” from the
housing to clear the transducer.
7. Slide the fluid section and piston rod forward until the piston
rod is out of the T-slot on the connecting rod.
8. Using a wrench, remove the transducer assembly from the
fluid section.
9. Thread the new transducer assembly from the fluid section.
Tighten securely with a wrench.
10. Reassemble the pump by reversing steps 1-8.
ImPORTANT: make sure the transducer is aligned properly
with the hole in the fluid section during reassembly. Improper
alignment may cause damage to the transducer O-ring.

Servicing the clutch Assembly
NOTE: When replacing the clutch armature, the clutch
rotor must be replaced also. This will allow for even
wear and maximum life on clutch parts.
Removing/Replacing the clutch Armature Assembly
1. Perform the Pressure Relief Procedure.
2. Locate the wire that exits the rear of the pressure control
housing and connects to the wire harness on the engine.
Disconnect this wire from its connector at the engine wire
harness.
3. Using a 12 point, 5/16” wrench, remove the four screws
and lock washers that secure the clutch housing to the gear
housing.
4. Using a 9/16” socket, remove the screw that secures the gear
housing to the cart.
5. Slide the pump and gear housings away from the engine to
disengage them from the clutch housing.

6. Locate the clutch armature assembly on the end of the engine
shaft. Note the two set screws as well as the unused, threaded
hole in the taper lock bushing at the center of the clutch hub.
7. Using an 1/8” hex wrench, remove the two set screws from the
taper lock bushing
8. Thread one of the set screws into the unused, threaded hole
on the taper lock bushing. As the screw tightens, the bushing
will loosen. Once the bushing has loosened enough, slide the
clutch armature assembly off the engine shaft.

9. Before replacing the clutch hub
and armature assembly the proper
“set back” must be created. Using
the Titan hub set-up tool (P/N
0555926), create a “set back” of
0.10” between the friction surface
of the clutch armature and the
forward face of the clutch hub.
NOTE: A new clutch hub and
armature assembly will come
pre-assembled, but the “set
back” may not be correct.
The “set back” must still be
created using the hub set-up
tool.
0.10"
10. To replace the clutch armature assembly , line up the three
holes in the taper lock bushing with the three holes in the
clutch armature and insert the bushing into the center of the
clutch armature.
11. Line up the key on the taper lock bushing with the keyway on
the engine shaft and slide the assembly onto the shaft with
the holes facing out.
12. Apply blue Loctite to the two set screws and insert the screws
into the taper lock bushing. Tighten the set screws only two
turns at this time.
