14. Grasp the Trigger (17) and pull the assembled throttle
out of the Motor Housing.
15. Using a pin punch and without damaging the Trigger,
remove the Trigger Pin (18).
16. Slide the Throttle Bushing Assembly (10) off the shaft
of the Throttle Rod Assembly (15).
17. Using a thin blade screwdriver, remove the Valve
Retaining Ring (14) and slide the Throttle Valve
Assembly (12) off the shaft of the Throttle Valve Rod.
18. Using an adjustable wrench, unscrew and remove
the Inlet Bushing (20) and Exhaust Deflector
Assembly (21).
19. Insert a threaded rod through the Cylinder and Front
End Plate and install a nut and washer on the end
plate end of the rod. Position the Rear End Plate on
the threaded rod against the Cylinder and clamp the
End Plates and Cylinder snug with another nut and
washer. Do not tighten the assembly excessively.
20. Using a heat induction coil or an oven, heat the
assembly and Housing until it is warm enough to pull
the assembly out the rear of the Motor Housing. Do
not apply enough heat to distort the Housing.
Take all precautions necessary to prevent being
burned by handling warm or hot parts.
ASSEMBLY
General Instructions
1. When grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws to
protect the surface of the part and help prevent
distortion. This is particularly true of threaded
members and housings.
2. Always press on the inner ring of a ball–type bearing
when installing the bearing on a shaft.
3. Always press on the outer ring of a ball–type bearing
when pressing the bearing into a bearing recess.
4. Except for bearings and mechanism parts, always
clean every part and wipe every part with a thin film
of oil before installation.
5. Wipe a thin film of mechanism fluid on all internal
mechanism components before installing them in the
mechanism.
6. Apply a film of O–ring lubricant to every O–ring
before installation.
Assembly of the Motor
1. Using an arbor press and a piece of tubing that
contacts the outer ring of the bearings, press the Front
Rotor Bearing (30) into the Front End Plate (29) and
the Rear Rotor Bearing (24) into the Rear End Plate
(22). (Refer to Dwg. TPD1274.)

2. Stand the Rotor (27) on the table of an arbor press. It
should be upright on a flat metal plate having a
clearance hole for the shaft. The shaft with the hex
must be upward.
3. 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 Front Rotor Bearing and Front End
Plate, End Plate leading, onto the shaft of the Rotor
until the End Plate contacts the shim. Remove the
shim. (Refer to Dwg. TPD1275.)

4. Coat each Vane (28) 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.
5. Install the Cylinder Assembly (25) over the Vanes and
Rotor making certain the Cylinder Alignment Pin (26)
enters the hole in the face of the Front End Plate.
6. Stand the assembly on an arbor press table so that the
rotor shaft on the front end plate end contacts the
table. Press the Rear End Plate Assembly, bearing end
trailing, onto the rotor shaft against the Cylinder.
Make certain the Cylinder Alignment Pin (26) enters
the hole in the face of the Rear End Plate.
7. Stand the assembly on a table with the Front End
Plate Assembly upward.
