COUNTERSHAFT

1. To raise the gear cluster and dummy shaft to align
with the countershaft holes in case, insert two
suitable punches through countershaft hole s in the
transmission case and engage the 3/16" holes
drilled in ends of dummy shaft. Raise the gear c l
u s t e r assembly to alignment with the counter-
shaft hole s in the case and while forcing the
countershaft cluster against the case with one pin
punch to maintain alignment remove the other pin
punch and start the countershaft through rear of
case.
2. Tap the countershaft forward and hold front end of
dummy shaft to keep constant contact with the
countershaft at all times to prevent thrust washers
and needle rollers from dropping from gear clus-
ter. Line up slot in countershaft w ith slot in idler
gear shaft and install lock plate. Drive both shafts
in case securely to retain lockplate.

holes of clutch housing to assist in supporting the
transmission during installation.
2. Raise the transmission assembly into position and
enter guide studs in top holes of case flange.
3. Check the position of the clutch driving plate and
see that it is perfectly centralized within the clutch
assembly. Use 1-5442 Aligning Arbor for this oper-
ation.
4. Move the assembly forward and engage mainshaft
splines in clutch plate hub. Be sure the throwout
bearing and collar are properly positioned in the
throwout lever.
5. Install the clutch cross shaft support assembly to the

washers and tighten nuts 14-17 ft. albs., be sure
bearing cups are properly seated under retaining
lugs of companion flange.
10. Tighten drain plugs, remove filler plug and fill
