MAINTENANCE SECTION
5. Press two Planet Gear Bearings (80) into each of the
Planet Gears (79).
6. Insert an assembled Planet Gear into each slot in the
Gear Head, capturing the Rotor Pinion (82) in the
Gear Head, and retain the Planet Gears by pressing
the Planet Gear Shafts (81) from the smooth outside
diameter end of the Gear Head.
7. Slide the Gear Head Spacer (83) over the geared end
of the Gear Head and insert this assembly into the
ear Case. Make certain the Gear Head properly
meshes with the Spindle Planet Gears Assembly (85).
8. Place the Gear Case Assembly on the workbench with
the small diameter up and slide the Spindle
Spacer (88) onto the end of the Spindle.
9. Support the motor end of the Gear Head and press the
front Spindle Bearing (89) onto the Spindle.
10. Turn the Gear Case end for end and place the Motor
Clamp Washer (75), concave (dished) face first, over
the Gear Head. Make certain that the outside
diameter of the Motor Clamp Washer contacts the end
of the shoulder in the Gear Case.
11. Slide the Reaction Bar Adapter Assembly (91) over
the Gear Case Assembly. Secure it to the Gear Case
by tightening the Adapter Bolt (93). Place the Torque
Reaction Bar (94) into the Reaction Bar Holder
Assembly and secure it with the Bar Lock Screw (92).
12. Press the Gear Head Bearing (90) into the large recess
in the Front Rotor Bearing Support and slide the
Bearing onto the hub of the Gear Head.
13. Thread the assembled Gear Case onto the assembled
Motor Housing (1) and tighten to a minimum of
35 ft–lb (47 Nm) torque.
Assembly of Angle Attachment
1. Lubricate the Bevel Pinion (104) as instructed in
LUBRICATION and insert it, gear end first, into the
long bore of the Angle Housing Assembly (100).
2. Lubricate the Bevel Pinion Bearing (106) as
instructed in LUBRICATION and insert it,
unstamped end first, into the bore of the Angle
Housing, after the Bevel Pinion.
3. Using a bearing inserting tool, see Dwg. TPD786,
press the Bearing so the stamped face is 1–11/32” (34
mm) below the end face of the Angle Housing.
4. Install the Front Seal (108) and the Rear Seal (109)
onto the Bevel Pinion Bearing Spacer (107).
5. Insert the Spacer, small diameter first, into the long
bore of the Angle Housing and retain it using the
Bevel Spacer Retainer (121).
6. Lubricate the Bevel Pinion Thrust Bearing (110) as
instructed in LUBRICATION. Install, in the
following order; the Bevel Pinion Thrust Washer
(111), Bevel Pinion Thrust Bearing and the Bevel
Pinion Retainer (113), recessed face trailing, over the
splined end of the Bevel Pinion. Retain these parts
using the Bevel Pinion Snap Ring (112).
7. If the Lower Spindle Bearing (118) has been removed,
press the new Bearing onto the Socket Adapter
Spindle Assembly (114) with the red side closest to
the square drive end.
8. Press the Bevel Gear (105), geared side trailing, onto
the ground end of the Spindle and into contact with
the Lower Spindle Bearing.
9. For No. 8SA32 – Retain the Bevel Gear using the
Bevel Gear Retainer (119).
For No. 8SA53 and 9SA83 – Clean the threads on the
Spindle, apply a film of thread locking compound to
the threads, apply the Bevel Gear Lock Nut (120) and
tighten it to a minimum of 50 ft–lb (68 Nm) torque.
Press on the stamped face of the Upper Spindle
Bearing (103). Failure to do so will cause damage
to the Bearing.
10. If the Upper Spindle Bearing was removed, press a
new Bearing into the Angle Housing (100) from the
large threaded end to the dimension, shown in
Dwg. TPD636 and Table B.
