SHIMMING BEVEL PINION, NO. 382461.
Place housing cover 382582, or 382591 on right angle
housing and secure with two (2) cap screws 865123.
Place .040" of shims into R. A. housing and screw in
final planetary assembly snugly against shims. Use an
empty motor housing or empty internal gear case to
clamp the final planetary in place.
Insert the rapid advance clutch assembly and tighten
clutch cover 382537 lightly. Using a punch or rod
through the shear pin hole, the bevel gear 382474
should rotate freely without interference with the bevel
pinion 382461. Loosen and remove .005" or .010"
shims one at a time and retighten final planetary.
When a definite resistance to gear rotation is felt,
add one (1) .010" shim and retighten securely (40 ft.
Ib.— 54.2 Nm minimum) using the flats on the motor
housing or internal gear case. Tighten the lock ring
