Gear Case Service (Fig. 41)
The gear case is a pinion and gear reduction drive that
actuates the water valve. The pinion (Item 12) is con-
nected to the electric brake clutch with a drive coupler.
The gear (Item 22) moves the cam over the roller
follower, actuating the water valve to control water in-
jection at 5.3 cycles per second (at 320 RPM).
you inspect the cam and not the weight block, when
checking for wear. DO NOT INSTALL TWO CAMS
ONTO THE GEAR.
The cam (Item 23) can be replaced without removing or
disassembling the gear case. Evenly torque capscrews
securing cam to 22 - 28 ft-lb.
The gear case also serves as the hydraulic oil reservoir.
NOTE: If there is wear on the teeth of the gear (Item 22),
interchange the locations of the cam (Item 22) and
weight block (Item 27) so higher gear teeth load occurs
in a new location.
If the gear case is disassembled for repair, make sure
the taper roller bearings have a light rolling resistance
after reassembly by adjusting shim thicknesses
(Item 16 and 20). Bearing pre-load is 0 to 0.002 in.
After replacingthe camor repairing or replacingthegear
case, adjust water valve lift (see Water Valve Lift in the
Adjustments section).
There is a replaceable cam (Item 23) and weight block
(Item 27) on the gear. Only the cam contacts the roller
cam follower. Theweightblock is for balance.Make sure
