17. Grasp the handle of the Motor Housing in vise jaws
with the rotor shaft upward. Thread the Front End
Plate Spacer (34) into the Housing and using the end
plate spacer spanner, tighten the Spacer to 27 ft-lb (38
Nm) torque. This is a left-handed thread; rotate the
wrench counterclockwise to tighten.
18. After installing the Front End Plate Spacer, grasp the
shaft of the Rotor and rotate it by hand. If the Rotor
does not turn easily, disassemble the motor unit and
determine where the assembly is binding. The motor
must rotate freely before proceeding further with the
assembly. Now install the Silencer (5) into the Exhaust
Cover (6) followed by O-Ring (4).
❑ Go to Step 22 for Models 40PSQ1, 45PS3,

Assembly into the Motor Housing. It may be necessary
to tap the assembly into position with a brass or plastic
hammer.
20. Secure the Cover to the Housing by installing the
Screws (53) and Lock Washers (54). Tighten each
Screw between 45 and 50 in-lb (5.1 and 5.6 Nm)
torque.
21. Install Silencer (5) into the Exhaust Cover, followed by
Screen (J) and O-Ring (4).
22. Install O-Ring (7) onto the Hose Joint Assembly,
followed by the Exhaust Cover Assembly.
23. Coat the Hose Joint Assembly thread with thread lock
and secure it to the Housing.

Bushing. Install the Spring and Detent Ball, then
carefully push the Reverse Valve the rest of the way
into the Throttle Bushing.
29. Insure that the Detent Ball is aligned with one of the
holes in the side of the Throttle Bushing.
30. Install the O-Ring in the groove on the Throttle
Bushing.
31. Assemble the Reverse Lever onto the Reverse Valve
and secure with a Roll Pin.
32. Insert the Throttle Valve Assembly through the Reverse
Valve, then secure with the Throttle Knob and a Roll
Pin.
33. Insert the Trigger and Reverse Valve Assembly into the
Motor Housing, taking care to align the slots in the
Reverse Valve and Throttle Bushing with the pin hole
in the Motor Housing.
34. Secure Trigger and Reverse Valve Assembly with pin,
which should be centered from side to side.
35. To prevent air leakage, after pin assembly seal each
end of the pin with cement.

the end face of that wall is for the Relief Valve (70).
Install the Relief Valve and Spring Guide Assembly
into this hole.
3. Insert the Spring (65), Spring Guide (66) (with the
large end trailing), the Check Valve Ball (67) and
Check Valve Assembly into the hole on the opposite
wall of the Liner.

the Blade Springs (74) through the Drive Shaft and
into the holes in the blade. Place the remaining Blade
on the Springs, making certain the Springs enter the
holes in the blade.
