Chapter IlI—Transmission
required to obtain this torque reading. Removing one 0.005 inch shim
will increase the torque approximately
10 pounds-inches. Adding a
0.005 inch shim will decrease the torque a like amount.
Main shaft
shims can be changed by supporting
the rear
main
shaft bearing
retainer
over
the power
take-off shift shaft and
sliding the shims
in or out.
If it has been necessary to replace any of the transmission gears, a
careful check should be madé to make sure that all gears mesh prop-
erly. Install the power
take-off shaft in the power
take-off shift
assembly. Engage the power take-off shaft with the transmission.
Position the transmission in neutral and measure the torque required
to turn the power take-off shaft. With the shaft turning uniformly,
the torque should be from 30 to 60 pounds-inches. If more than 60
pounds-inches of torque are required to turn the shaft, one or more
of the gears are binding at the teeth or on the hub shoulders. Deter-
mine which gear is binding and replace it.
Position the shift plates in the housing and install the shift plate
cap screws. Install the upper shift fork and shift rail, positioning the
deep square corner slot in the rail toward the opening in the shift
plates. Install the interlock ball and spring in the hole at the top of
the housing. Using a new gasket, install the transmission cover.
