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) Bushing is correctly installed if 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) Bearing is correctly installed if 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 bushing in the detent plunger bore in
the case.
(e) Drive 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 bushing into the bore until the tool
contacts the transmission case.

(4) Assemble shift shaft shift lever and bushing
(Fig. 102). Verify slot in bushing is facing up and roll
pin hole for lever is aligned with hole in shaft.
(5) Install assembled lever and bushing on shift
shaft (Fig. 103).(6) Slide shift shaft through 1-2 and fifth-reverse
fork and into shift lever opening in rear housing (Fig.
104).
(7) Align shift socket with shaft and slide shaft
through socket and into shift shaft bearing in rear
housing (Fig. 105).
(8) Rotate shift shaft so detent notches in shaft are
facing the TOP of the transmission housing.
CAUTION: Both shaft roll pins can be installed
when the shaft is 180É off. If this occurs, the trans-
mission will have to be disassembled again to cor-
rect shaft alignment.

(9) Select correctnewroll pin for shift shaft lever
(Fig. 106). Shaft lever roll pin is approximately 22
mm (7/8 in.) long. Shift socket roll pin is approxi-
mately 33 mm (1-1/4 in.) long.
(10) Align roll pin holes in shift shaft, lever and
bushing. Then start roll pin into shaft lever by hand
(Fig. 107).(11) Seat shaft lever roll pin with pin punch (Fig.
108).
CAUTION: Shaft lever roll pin must be flush with
the surface of the lever. The lever bushing will bind
on the roll pin if the pin is not seated flush.
(12) Verify that lock pin slot in lever bushing is
positioned as shown (Fig. 108).
