NOTE: Do not replace the input shaft seal at this
time. A new seal will be installed after all the pre-
load measurements are made and endplay shims
are installed.

8246 and verify that all gears are meshed with their
mates on the output shaft (Fig. 78).
(6) Install Fixture 8232 to the output shaft and
countershaft.
(7) Install Holding Tool 8242 onto the 5-6 synchro
and tighten the screw to hold the 5-6 synchro
together during the remainder of the installation pro-
cedure.
(8) Attach a engine crane or equivalent to Fixture
8232 and move the geartrain from the Support Stand
8246 to the clutch housing (Fig. 79).
(9) Install shift forks and rails onto the geartrain
(Fig. 80).
NOTE: The closest shift arm to the geartrain is for
Reverse. The next is 5-6, then 3-4 and then 1-2
when moving out from the geartrain.
(10) Install geartrain and shift rails into the clutch
housing. Lower the geartrain and rails into the hous-
ing slowly while guiding input shaft through input
shaft seal. Avoid any binds on the shift rails, forks
and synchros as the rails enter their bushings.
