3. Carefully lower cluster and assembled parts into position
and enter front end of countershaft at rear of transmission
case, tapping it forward while holding the front end
of the dummy shaft in constant contact with the countershaft
to keep needle rollers and washers in place. Drive
countershaft forward just far enough to enter front end
in case, as it must again be removed after checking end
play.
4. With a feeler gauge inserted between the rear thrust
washers, check countershaft cluster end play, Figure 43.
End play should range between .006" and .016"; if more
than this, the thrust washers should be replaced.

on shaft with a soft hammer, drive out countershaft through
rear of case, using care to keep ends of shafts together at all
times. Lower countershaft cluster with dummy shaft in
place, to bottom of case.
REVERSE IDLER GEAR
1. Place reverse idler gear in position in case (1 on g hub
toward front) and drive idler gear shaft in from rear of the
case. Before fully Installing shaft, make sure slot for lock
plate is properly aligned with countershaft so plate will
seat in both slots. Idler gear end play should be from
.003" to .010".

4. Assemble synchronizer hub, shift plates, shift sleeve , springs and
synchronizer rings together as a unit and slide on mainshaft splines
the long hub of the sleeve pointing forward. Be sure that marks
painted on parts during disassembly are in proper alignment, also
that the hooked ends of the two synchronizer springs engage in the
same shift plate.
5. Install snap ring on front of mainshaft and check end play by
inserting a feeler gauge between the rear face of the mainshaft
second speed gear and the front ends of the mainshaft spiral
splines. This should be from .003" to .016". Excessive end play at
this point can only be corrected by Installing new parts.

move mainshaft and parts toward shift fork and engage fork in
