55. Bearing cage (1)

Pinion shaft

a. Put on.

and ring and

gear (3)

b. Put assembly in machinist's vise

pinion gear (2)

with soft jaws so gear (3) is held

firmly.

56.

Washer (4) and

a. Rotate cage (1) and, at the same

drive pinion

time, screw on nut (5) and tighten to

nut (5)

325 ft-lb (441 N m) of torque using

1 518-inch socket and torque wrench

with 3/4-inch drive.

Be sure to turn cage while

tightening nut so pinion bear-

ing cones will line up and seat.

Bearing rollers must be seated

against face of cone.

57. Pinion

Bearing cage (1)

a. Measure bearing preload by wrapping

assembly (6)

a strong cord or soft wire around

bearing cage (1) and attaching end

to suitable spring scale.

b. Pull on scale and note reading while

rotating cage.

Scale reading should show 3 - 8 lb

(1.35 - 3.6 kg).

NOTE

When preload does not agree with specification (3 - 8 lb, 1.35 - 3.6 kg) bearing load may be increased by installing a

thicker spacer. If necessary, go back to disassembly to remove spacer. Measure thickness of old spacer with

caliper micrometer and select a different spacer. Spacers are available in various thicknesses, in graduations of

0.001 inch (0.025 mm). Closer adjustment can be made by working spacer to desired thickness using an emery

cloth on flat surface. Be sure to clean off emery cutting before installing spacer.
