MAINTENANCE SECTION
Assembly of the Gearing
1. If the Grease Shield Retainer (60) was removed,
install it in the second groove below the front face of
the Gear Case (56).
2. Support the face of the Spindle (43), pin end
downward, on the table of an arbor press.
3. Install the Seal Support (44), large end first, and
Grease Shield (59) over the hub of the Spindle.
4. Using a sleeve that contacts the inner ring of the
Bearing, press the Spindle Bearing (61) onto the hub
of the Spindle until the Bearing seats against the Seal
Support.
5. Insert the assembled Spindle, pin end first, into the
front end of the Gear Case until the Grease Shield is
flush against the Grease Shield Retainer.
6. Using snap ring pliers, install the Spindle Bearing
Retainer (62) in the groove ahead of the Spindle
Bearing.
Always press on the stamped end of the Spindle
Planet Gear Bearings (47) and center the Bearing
in the Gear.
7. If the Spindle Planet Gear Bearings are being
replaced, use a bearing inserting tool, shown in
Dwg. TPD488, and press the Bearings into the
Spindle Planet Gears (46).
8. Grease the Bearings and Gears and install them on the
pins of the Spindle.
9. For M, N, P, Q, or R ratio, install the Gear Head
Spacer (55) in the Gear Case against the Spindle
Planet Gears.
10. For M, N, P, Q or R ratio, grease the splined hub of
the Gear Head (50) and insert it into the Gear Case.
The splined hub must pass through the Gear Head
Spacer and mesh with the teeth of the Spindle Planet
Gears.
Always press on the stamped end of the Bearing
and center the Gear Head Planet Gear Bearings
(52) in the Gear.
11. For N, P, Q or R ratio, if the Gear Head Planet Gear
Bearings (52) are being replaced, use a bearing
inserting tool similar to the one used with the Spindle
Planet Gear Bearings and press the Bearings into the
Gear Head Planet Gears (51).
For M ratio, push the Gear Head Planet Gear
Bearing (54) into the Gear Head Planet Gear (53).
12. For M, N, P, Q or R ratio, grease the Bearings and
Gears and install them on the pins of the Gear Head.
13. For M, N or P ratio, grease the Rotor Pinion (49)
and install it in the center of the Gear Head Planet
Gears. Make certain the teeth of the Pinion and
Planet Gears mesh.
14. Using snap ring pliers, install the Gear Retainer (48)
in the shallow internal groove in the Gear Case
behind the Spindle Planet Gears or Gear Head Planet
Gears.
15. For 6WT or 6WRT, install the Exhaust Deflector
(64) as follows:
a. Install the two Exhaust Deflector Seals (65) in the
annular grooves on each side of the Muffler
Element (63) recess on the Gear Case.
Make certain the hole through the Muffler
Element aligns with the Grease Fitting (57) in
the Gear Case.
b. Wrap the Muffler Element around the Gear Case
in the recess.
c. Slip the Exhaust Deflector, largest inside diameter
first, onto the front end of the Gear Case and over
the Muffler Element and Exhaust Deflector Seals.
d. Spread the ends of the Deflector Retaining Ring
(66) and install it in the external groove in the
Gear Case adjacent to the front of the Exhaust
Deflector.
16. Thread the assembled Gear Case onto the assembled
Motor Housing until it is hand tight. Make certain the
gear teeth on the Spindle mesh with the gear teeth of
the Rotor Pinion, Gear Head Planet Gears or Spindle
Planet Gears.
Run the motor at free speed on low air pressure
while final tightening the Gear Case. Listen while
tightening to make certain the gears mesh
properly.
17. Tighten the Gear Case between 30 to 35 ft–lb (41 to
47 Nm) torque.
Assembly of the Angle Attachment
1. Lubricate the Bevel Pinion (105) as instructed under
LUBRICATION and insert it, gear end first, into the
long bore of the Angle Housing (101).
2. Lubricate the Bevel Pinion Bearing (106) as
instructed under LUBRICATION and insert it,
unstamped end first, into the bore of the Angle
Housing and onto the bevel pinion shaft.
