ASSEMBLY
General Instructions
1. When grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws to pro-
tect the surface of the part and help prevent distor-
tion. 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 be-
fore installation.
Assembly of the Motor
1. Thread the Inlet Bushing (20) into the bottom of the
handle of the Motor Housing (1) and tighten it be-
tween 30 and 35 ft–lb (40 and 47 Nm) torque.
2. Position the Exhaust Deflector Assembly (21) in the
bottom of the motor housing handle and install the
Deflector Retaining Pin (22) to secure it in position.
It may be necessary to slide the Assembly in or out
in order to align the groove in the Assembly with
the pin hole.
3. Install the Throttle Rod Seal (13) in the groove on the
large hub of the Throttle Rod (12).
4. Install the Throttle Valve Seal (10) in the groove on
the large hub of the Throttle Valve (9).
5. Slide the Throttle Valve, Valve Seal end first, onto the
Throttle Valve Rod.
6. Secure the Throttle Valve Assembly by installing the
Valve Retaining Ring (11) in the small groove on the
Throttle Valve Rod.
7. Install the three Throttle Bushing Seals (8) in the
grooves on the Throttle Bushing (7).
8. Slide the Throttle Bushing Assembly onto the shaft of
the Throttle Valve Rod and position the Trigger (14)
on the same shaft. Install the Trigger Pin (15).
9. Insert the assembled Trigger into the Housing. Make
certain the widest end of the Trigger is nearest the
motor bore and the narrowest portion of the Throttle
Valve aligns with hole for the Throttle Retaining Pin
(16). Install the Pin making certain it captures the
Throttle Valve and secures the assembled Trigger.

leading, into the motor bore of the Housing. Insert the
small hub through the Housing until it protrudes
through the rear of the Housing. Position a 1–1/4" (32
mm) diameter metal rod about 3" (75 mm) long
against the face of the Reverse Valve and stand the
rod on a workbench with the weight of the Housing
compressing the Reverse Valve Spring.
by the Reverse Lever Detent Ball (5) into the hole in
the face at the rear of the Motor Housing. Capture the
Ball and Spring in position by installing the Reverse
Lever (3) onto the hub of the Reverse Valve. Make
certain the Reverse Lever Alignment Pin (2) enters
the notch on the face of the Lever and that the cros-
shole in the hub of the Reverse Valve aligns with the
crosshole in the Lever. (Refer to Dwg. TPD1273).

Valve. Remove the assembly from the metal rod and
work the Lever several times to make certain all parts
function smoothly.

End Plate Bearing (34) into the Front End Plate (32)
and the Rear End Plate Bearing (26) into the Rear
End Plate (25). (Refer to Dwg. TPD1274)
