and the countershaft.
(12) Separate the countershaft from the output
shaft.

NOTE: Some gear and synchro components can be
installed backwards. To avoid assembly problems,
mark the gears, clutch gears, synchro hubs, and
sleeves for reference during teardown. Use paint or
a scriber for marking purposes. Then stack the
geartrain parts in order of removal. This practice
will help avoid incorrect assembly.
