4. For 7L3D6 Angle Head, insert the Spacer Assembly over the
splined end of the Bevel Pinion and into the Angle Housing until it is
beyond the Spacer Retainer groove. Using a thin blade screwdriver,
start the end of the Bearing Spacer Retainer opposite the tab end
into the groove in the Angle Housing. Rotate the screwdriver around
the pinion shaft to spiral the Retainer into the groove.
For 6L2D6 Angle Head, insert the Pinion Bearing Spacer over the
splined end of the Bevel Pinion and into the Angle Housing until
it is beyond the Spacer Retainer groove. Using snap ring pliers,
install the Bearing Spacer Retainer in the groove in the Angle
Housing.
5. Lubricate the Bevel Pinion Thrust Bearing (112) as instructed under
LUBRICATION. Install, in the order named, the Front Thrust Bearing
Seat (109), Bevel Pinion Thrust Bearing and Rear Thrust Bearing
Seat (107) over the splined end of the Bevel Pinion and retain the
components by installing the Bearing Seat Retainer (108) on the
pinion shaft.
6. If the Lower Spindle Bearing (113) has been removed, proceed as
follows:
a. For 7L3D6 Angle Head, using a sleeve that will contact the
inner ring of the Bearing, press the Bearing onto the Spindle
(118). Press on the stamped side of the Bearing with the side
marked with red toward the spindle shoulder.
For 6L2D6 Angle Head, using a sleeve that will contact the
inner ring of the Bearing, press the Bearing, sealed side first,
onto the Spindle (118).
b. For 7L3D6 Angle Head, press the Bevel Gear (105) onto the
Spindle.
For 6L2D6 Angle Head, slide the Bevel Gear (105) onto the
Spindle.
c. For 7L3D6 Angle Head, spread the Bevel Gear Retainer (114)
and slip it over the end of the Spindle. Slide the Retainer down
the Spindle and into the groove around the Spindle to retain
the Bevel Gear.
For 6L2D6 Angle Head, apply a quality thread-locking
compound to the threads of the Bevel Gear Retainer and
tighten it on the Spindle to 10 ft-lb (13.5 Nm) torque.
CAUTION
Press on the stamped face of the Upper Spindle Bearing (104).
Failure to do so will cause damage to the Bearing.
7. If the Upper Spindle Bearing has been removed, proceed as
follows:
For 7L3D6 Angle Head, press a new Spindle Bearing into the
Angle Head from the large threaded end to the dimension
shown. Install a new Angle Housing Cap (103) into the top of the
Angle Head. See Dwg. TPD636.

8. Lubricate the Upper Spindle Bearing, Bevel Gear and Lower
Spindle Bearing as instructed under LUBRICATION and install the
Spindle in the Angle Housing.
9. Clean the threads on the Angle Housing and the Spindle Bearing
Cap (120) and apply a film of Vibra-Tite®** VC3 to the threads.
10. For 7L3D6 Angle Head, using No. 8SA32-26 Lower Bearing Cap
Wrench, install the Spindle Bearing Cap and tighten the Cap to a
minimum of 25 ft-lb (34.0 Nm) torque.
For 6L2D6 Angle Head, install Spindle Seal (120A). Using
No. 141A12-26 Lower Bearing Cap Wrench, install the Spindle
Bearing Cap and tighten the Cap to a minimum of 15 ft-lb (120.0
Nm) torque.
11. Slide the Coupling Nut (122), threaded end trailing, over the
splined end of the Angle Housing.
12. Apply the Coupling Nut Retainer (121) to the external groove on
the splined end of the Angle Housing.
13. Engage the spline on the Bevel Pinion with the matching internal
spline of the Spindle (43) and thread the Coupling Nut onto the
Gear Case (56). Tighten the Coupling Nut to a minimum of
25 ft-lb (34.0 Nm) torque. Check to make sure the square drive of
the Angle Attachment aligns with the Throttle Lever (4).
