insert a hooked tool through the central opening of
the Seat and, catching the underside of the Seat, pull
it from the Housing.

ASSEMBLY
General Instructions
1. Always press on the inner ring of a ball–type bearing
when installing the bearing on a shaft.
2. Always press on the outer ring of a ball–type bearing
when pressing the bearing into a bearing recess.
3. Whenever grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws. Take
extra care not to damage threads or distort housings.
4. Except for bearings, always clean every part and wipe
every part with a thin film of oil before installation.
5. Check every bearing for roughness. If an open bearing
must be cleaned, wash it thoroughly in clean solution
and dry with a clean cloth. Sealed or shielded
bearings should not be cleaned. Work grease into
every open bearing before installation.
6. Apply a film of o–ring lubricant to every O–ring

Unless otherwise noted, always press on the stamped
end of a needle bearing when installing a needle
bearing into a recess.
Insert the Throttle Valve Plunger (8) into the Motor
Housing (5).
Position the Throttle Lever (6) on the Motor Housing
and using an arbor press, press the Throttle Lever Pin
(7) into the Housing and Lever. The Lever will retain
the Plunger in the Housing.
If the Throttle Valve Cartridge Case (4) was removed,
lubricate the outside and the throttle stem end of the
Case with o–ring lubricant. Using a wooden dowel,
push the Case, open end trailing, into the Motor
Housing.
If the Throttle Valve Seat (4A) was removed, use a
5/8" wooden dowel with a flat end to push the Seat
into the Motor Housing.
Push the small end of the Throttle Valve Spring (4C)
onto the end of the Throttle Valve (4B) with the short
stem until the Spring snaps into position around the
hub and remains there. Install the dish end of the
Throttle Valve Spring Seat (4D) onto the large end of
the Throttle Valve Spring.
Holding the Housing with the Lever downward, make
sure the Plunger is out of the way and insert the
assembled Throttle Valve, long stem end leading, into
the housing recess.
Push the Inlet Screen (2), closed end leading, into the
bushing of the Inlet Assembly (1). After moistening
the Inlet Seal (3) with O–ring lubricant and being
careful not to nick the Seal on the threads of the Inlet,
install the Seal on the Inlet.
Thread the Inlet Assembly into the Housing and
tighten it between 20 and 25 ft–lb (27.1 and 33.9 Nm)
torque.
If the Rear Rotor Bearing (9) was removed, stand the
Rotor (12) upright on the table of an arbor press with
the threaded end downward. Place the threaded rotor
hub into a hole drilled into a flat, smooth block so that
the Rotor rests against the large rotor body. Press the
Rear Rotor Bearing, with the shielded side of the
Bearing against the rear end plate, onto the hub of the

Rotor.

Install the Rear Rotor Bearing Retainer (11) in the
groove on the hub of the Rotor.
Place the Front End Plate Spacer (15) onto the
threaded hub of the Rotor and install the Front End
Plate (14) around the Spacer, counterbored end
trailing. Press the Front Seal Cup (16), recess end
trailing, onto the Spacer until the trailing end is flush
with the Spacer.
