MATERIALS NEEDED-
• PIECE OF FLAT METAL STOCK ABOUT 5 MM (OR 3/16 IN.)
THICK, AND 55 MM (OR 2 1/4 IN.) SQUARE OR ROUND.
• THREE 6 MM OR 3/16 IN. BOLTS OF EQUAL LENGTH, LONG
ENOUGH TO EXTEND AT LEAST 35 MM (1 3/8 IN.) BELOW
THE FLAT STOCK WHEN INSTALLED THROUGH IT. TO USE
NUTS INSTEAD OF TAPPED HOLES, USE LONGER BOLTS
TO COMPENSATE FOR NUT THICKNESS.
1. LOCATE THREE HOLES EQUALLY AROUND A 32 MM
(1.26 IN.) CIRCLE ON FLAT STOCK. DRILL AND TAP
HOLES AS NEEDED TO MATCH BOLT THREADS.
2. INSTALL BOLTS IN FLAT STOCK AND TIGHTEN. ENDS
OF INSTALLED BOLTS SHOULD PASS THROUGH
ACCESS HOLES IN END OF DRIVE SHAFT WITHOUT
BINDING.

LUBRICATION
Armature bearings and the driveshaft support bearing
are permanently lubricated. Do not add lubricant to
these bearings. Using Delco Remy lubricant P/N
196094, lubricate the following areas during assembly.
Avoid using excessive grease.
• Drive end housing bushing in the drive housing.
• Pivot hole and working surface on the ends of the
shift lever.
• Internal gear, shaft, and spline on the drive shaft.
3. New pinion stop (36) and stop rings (35).
A. Slide the pinion stop (36) onto the driveshaft
(31). End with the recess for the stop rings fac­
ing up.
B. Install the stop rings (35) into the groove in the
drive shaft.
C. Pick the assembly up and support it under the
p in io n sto p (36). A m etal b lo ck, w ith a
U-shaped cutout that will slide over the shaft
between the pinion gear and stop, can be
clamped in a vise to provide support (figure 12).
D. Make sure the stop rings (35) (in the drive shaft
groove) are fully seated in the pinion stop
recess and stake the upper edge of the pinion
stop (36) over the stop ring (35) at four places,
equally spaced. Do not allow the staked metal
