SHIFT SHAFT AND DETENT PLUNGER BUSHINGS/BEARINGS
(1) Inspect shift shaft bushing and bearing for
damage.
(2) If necessary, the shift shaft bushing can be
replaced as follows:
(a) Locate a bolt that will thread into the bush-
ing without great effort.
(b) Thread the bolt into the bushing, allowing
the bolt to make its own threads in the bushing.
(c) Attach a slide hammer or suitable puller to
the bolt and remove bushing.
(d) Use the short end of Installer 8119 to install
the new bushing.
(e) The bushing is correctly installed if the bush-
ing is flush with the transmission case.
(3) If necessary, the shift shaft bearing can be
replaced as follows:
(a) Locate a bolt that will thread into the bear-
ing without great effort.
(b) Thread the bolt into the bearing as much as
possible.
(c) Attach a slide hammer or suitable puller to
the bolt and remove the bearing.
(d) Use the short end of Installer 8119 to install
the new bearing.
(e) The bearing is correctly installed if the bear-
ing is flush with the transmission case.
(4) Inspect detent plunger bushings for damage.
NOTE: The detent plunger bushings are installed to
a specific depth. The space between the two bush-
ings when correctly installed contain an oil feed
hole. Do not attempt to install the bushings with
anything other than the specified tool or this oil
hole may become restricted.
(5) If necessary, the detent plunger bushings can
be replaced as follows:
(a) Using the long end of Installer 8119, drive
the detent bushings through the outer case and
into the shift shaft bore.
(b) Remove the bushings from the shift shaft
bore.
(c) Install a new detent plunger bushing on the
long end of Installer 8118.
(d) Start the bushing in the detent plunger bore
in the case.
(e) Drive the bushing into the bore until the tool
contacts the transmission case.
(f) Install a new detent plunger bushing on the
short end of Installer 8118.
(g) Start the bushing in the detent plunger bore
in the case.
(h) Drive the bushing into the bore until the tool
contacts the transmission case.
GEARTRAIN ASSEMBLY
(1) Install Adapter 6747-1A on input shaft hub of
fixture tool (Fig. 90). Then install Adapter 6747-2A
on front bearing hub of countershaft. Adapter
6747-2A has a raised shoulder on one side. Be sure
the shoulder is seated against the countershaft.
(2) Install input shaft in fixture tool. Make sure
Adapter Tool 6747-1A is positioned under shaft as
shown (Fig. 91).
(3) Install pilot bearing in input shaft (Fig. 91).
NOTE: There is a correct and an incorrect way to
install the pilot bearing into the input shaft. The
side of the pilot bearing with the small diameter
goes toward the input shaft.
