3. For 7L3D6 Angle Head, use No. 7L3A–950 Bearing
Inserting Tool and press the Bevel Pinion Bearing so
the stamped face is a maximum of 1.35” (34.4 mm),
but not less than 1.34” (34.1 mm) below the end face
of the Angle Housing.
For 6L2D6 Angle Head, use No. 7L2A–950 Bearing
Inserting Tool and press the Bevel Pinion Bearing so
the stamped face is a maximum of 1.65” (42.0 mm),
but not less than 1.64” (41.75 mm) below the end face
of the Angle Housing.
Check to make sure the Bearing Spacer Retainer
(111) is completely seated.
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.
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.
