For Models Q60P3, Q70P3, Q70PQ1, Q80P3, Q80PQ1 and
Q90P3, place the Ball (18b) and Spring (17a) in the back of the
Throttle Valve (14). Place the Rubber Pad (15) on the front of the
Throttle Valve. Insert the Throttle Valve Assembly into the back of
the Throttle Bushing (11). Replace the Throttle Bushing Cap (18a)
on the back of the Throttle Bushing to hold the Throttle Valve
Assembly in the Bushing.
6.
Insert Throttle Rod (16) into the back of the Reverse Valve,
rounded end first.
7.
For Model Q110P4, push the Throttle Rod (16) into the back of
the Throttle Rod Bushing (14a). Install the Snap Ring (18) to the
Throttle Rod. Insert Throttle Rod Bushing assembly into the back
of the Throttle Bushing.
8.
Start the Reverse Valve into the Throttle Bushing. Install the
Reverse Lever Detent Spring (22) in the hole in the Reverse Valve.
Set the Reverse Lever Detent Ball (23) on the Spring and while
holding it in place, align the Ball with the detent hole in the
Bushing. Push the Valve into the Bushing until the Reverse Lever
Detent Ball seats in the detent hole.
9.
Install the Trigger (26) on the Throttle Rod and secure it with the
Trigger Pin (27).
10.
Slide the assembled unit into the Motor Housing (1).
11.
Install the Throttle Retaining Pin (28) in the Housing, making sure
that it captures the Throttle Bushing Assembly.
12.
Using an arbor press and a piece of tubing that contacts the outer
ring of the bearings, press the Lower Plate Bearing (37) into the
Lower Plate (36) and the Upper Plate Bearing (31) into the Upper
Plate (30). (Refer to Dwg. TPD1274).

13. Stand the Rotor (34) on the table of an arbor press. It should be
upright on a flat metal plate having a clearance hole for the shaft.
The side with the internal hex must be down.
14. Place a 0.001" (0.025 mm) shim on the upward surface of the
large portion of the rotor body. Using a piece of tubing that
contacts the inner ring of the bearing, press the Upper Bearing
and Upper Plate, Upper Plate leading, onto the shaft of the Rotor
until the Upper Plate contacts the shim. Remove the shim. (Refer
to Dwg.TPD1275).

15. Coat each Vane (35) with a thin film of oil and insert a Vane into
each of the rotor vane slots with the straight edge of the Vane
outward.
16. Install the Cylinder (32) over the Vanes and Rotor with the end
of the Cylinder having the two holes diagonal from each other
toward the Upper Plate. Make certain the Pin enters the hole in
the face of the Upper Plate. (Refer to Dwg TPD1276).

17. Press the Lower Plate and Bearing against the face of the Cylinder,
Bearing end trailing.
18. Insert the two O-Rings (29) into the back of the Motor Housing.
19. Insert the Motor Assembly into the Motor Housing, confirming
knock position. (Refer to Dwg. 16595993).
Knock Position
(Dwg. 16595993)
It may be necessary to tap the assembly into position with a brass
or plastic hammer. (Refer to Dwg. TPD1279).
(Dwg. TPD1279)
Grasp the handle of the Motor Housing in vise jaws with the
rotor shaft upward. Install the gasket (39). Thread the Lower Plate
Spacer (40) into the Housing and using the End Plate Spacer
Spanner-Jig F, tighten the Spacer to 23-29 ft-lb (31-39 Nm)
torque. This is a left-handed thread; rotate the wrench counter-
clockwise to tighten. (Refer to Dwg. TPD1280).
