of needle bearing area is less than 0.864 in. (21.95 mm)
or 0.982 in. (24.95 mm), replace the reduction shaft.
11. Inspect countershaft for wear or damage. If O.D. of
inner portion is less than 1.100 in. (27.95 mm) or 71T
gear portion is less than 1.179 in. (29.95 mm), replace
the countershaft.

A. Inspect pinion shaft for excessive wear or dam-
age. If O.D. is less than 0.707 in. (17.95 mm), replace

B. Measure thickness of pinion liners. If thickness is
less than 0.035 in. (0.9 mm), replace the pinion lin-
