21. Using a brass. drift move the countershaft rear-
ward just enough to free up the lock plate in the
shaft groove.
22. Use a dummy countershaft 11/16" diamete r
5-7/8" long, place end of dummy shaft against the
front end of the countershaft and carefully drive
the countershaft rearward out of transmission case.
CAUTION: Be sure the dummy shaft remains in
constant contact with the countershaft during re-

24. With the dummy shaft holding the needle rollers
and thrust washers in position, lift the countershaft
gear cluster up and out of transmission case.
NOTE: Remove the thrust washers from cluster
gear noting position to insure exact replacement.
25. Using a long brass drift, drive the reverse idler
gear shaft out of rear of transmission case and
remove idler gear.
26. Drive out taper pins (96) Figure 2, securing the
transmission shift shafts, (small end of taper pin is
down).
27. Remove nuts , washers and levers from shift shafts
and take shafts out of case. When doing this, also
