12. Thread the Inlet Bushing (21) into the bottom of the handle of the
Motor Housing (1) and tighten it between 30 and 35 ft–lb (40 and
47 Nm) torque.
13. Install the Throttle Rod Seal (17) in the groove on the large hub of
the Throttle Rod (16).
14. Install the Throttle Valve Seal (14) in the groove on the large hub
of the Throttle Valve (13).
15. Slide the Throttle Valve, Valve Seal end first, onto the Throttle
Valve Rod.
16. Secure the Throttle Valve Assembly by installing the Valve
Retaining Ring (15) in the small groove on the Throttle Valve Rod.
17. Install the three Throttle Bushing Seals (12) in the grooves on the
Throttle Bushing (11).
18. Slide the Throttle Bushing Assembly onto the shaft of the Throttle
Valve Rod and position the Trigger (18) on the same shaft. Install
the Trigger Pin (19).
19. Insert the assembled Trigger into the Housing. Make certain
the wider end of the Trigger is nearest the motor bore and the
narrower portion of the Throttle Valve aligns with hole for the
Throttle Retaining Pin (20). Install the Pin making certain it
captures the Throttle Valve and secures the assembled Trigger.
20. Align the detent hole in the Reverse Valve (6) with the hole inside
the Reverse Valve Bushing (5) and slide the Valve into the Bushing
until almost reaching the detent hole. Insert the Reverse Valve
Detent Spring (8) and Reverse Valve Detent Ball (7) into the hole
and while compressing the Spring with the Ball, slide the Valve
completely into the Bushing.
21. Using snap ring pliers, install the Reverse Valve Retainer (9).
22. Slide the Reverse Lever (2) onto the Reverse Valve, making certain
the Reverse Lever Alignment Pin (3) enters the notch on the face
of the Reverse Valve Bushing. Secure the Lever to the Valve by
inserting the Reverse Lever Retaining Pin (4).
Assembly of the Impulse Mechanism
1. Insert the long shaft of the Piston Stop (69) into the central
opening of the O–ring Installer furnished with the Tool Kit (Part
No. 700A–99). Place the Piston Stop Seal (70) on the tapered end
of the Installer and roll the Seal up the taper and into the groove
on the large body of the Piston Stop. Repeat the procedure with
the other Piston Stop and Seal.
2. When looking inside the central opening of the Liner Assembly
(66), the internal wall has three holes on one side which do not
extend through the wall. The opening on the end face of that wall
is for the Torque Valve Piston (68). Install the Torque Valve Piston,
large end trailing, into that opening.
3. Insert the Piston Stop Assist Spring (71) into hole in the end face
of the opposite wall.
4. Thread the Threaded Tee Wrench furnished with the Tool Kit into
one of the Piston Stop Assemblies and using the Wrench to hold
the Assembly, insert the Assembly into the opening against the
Piston. Mark this opening with a felt marker to indicate that it
contains the Torque Valve Piston.
5. Unscrew the Wrench and in the same manner, install the other
Piston Stop Assembly in the hole with the Spring.
6. Install the Rear Liner Cover Seal (72) in the annular groove on the
face of the Rear Liner Cover (73).
7. Install the two Front Liner Cover Piston Seals (59) in the openings
on the face of the Front Liner Cover.
8. Install the Seal Back–Up Ring (58) followed by the Drive Shaft
O–ring (57) in the central opening in the face of the Front Liner
Cover.
9. Insert the short round hub of the Drive Shaft (61) into the central
opening of the Rear Liner Cover.
10. Insert a Blade (64) into one slot in the Drive Shaft. Install the Blade
Springs (65) 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 that Blade.
11. Using finger pressure, compress the Springs with the Blades
until the outer edges of the Blades are flush with the drive shaft
surface. Capture the Blades in this position by installing the
Liner Assembly, piston stop end trailing, over the Drive Shaft and
against the Rear Liner Cover.
NOTICE
This installation can be accomplished more easily by aligning the
compressed Blades with the webs at the narrowest portion of the
opening. Keeping the Blades on the web allows them to slide the
length of the Liner without interference.
12. Insert the hex end of the Rear Liner Cover into the Disassembly
Arbor from the Tool Kit and stand it on a workbench with the
Drive Shaft upward.
13. Install the Front Liner Cover Assembly over the Drive Shaft and
against the Liner. Make certain the Torque Adjustment Screw
(52) aligns with the proper piston stop opening that was marked
during assembly.
14. Install the two Liner Cover Seals (60) in the grooves inside the
Liner Housing (50) near the end with the external wrench flats.
15. Place the Liner Housing, Seal end trailing, over the assembled
Liner. Make certain the notch in the trailing end face of the
Housing aligns with the Oil Plug (54) in the Front Liner Cover.
Use the Pressing Sleeve from the Tool Kit to press the Housing
over the Seals and into position. Do not Damage the Seals during
installation.
16. Grasp the flats of the Liner Housing in vise jaws and using the
Spanner Plug furnished with the Tool Kit and a torque wrench,
install the Housing Cap, castellated end leading.
NOTICE
This is a left–hand thread; rotate the wrench counterclockwise to
tighten the Cap.
Tighten the Cap on models 500P, 500PQ1 and 700P between 101 and
116 ft–lb (137 and 157 Nm) torque and on model 900P between 116
and 130 ft–lb (157 and 176 Nm) torque.
17. Make certain the Drive Shaft rotates freely and then fill the
mechanism with fluid and reassemble the tool as instructed in
the section, CHANGING THE MECHANISM FLUID.
