CONSTRUCTION
The transmission is of the all-helical gear type
with synchro-mesh second and high gears.
The rear of the main drive gear is supported by a
ball bearing mounted in the transmission case and the
front end pilots in a bronze bushing. The front end of
the main-shaft operates in rollers carried in the main
drive gear and the rear end of the main-shaft is sup-
ported by a ball bearing mounted in the case. Oil
retention is by means of a hydraulic leather oil seal in
the rear bearing retainer.
The main-shaft second speed gear and the
reverse idler gear operate on their shafts through
precision fitted, bronze alloy bushings. The coun-
tershaft gear cluster operates on the stationary
countershaft through needle rollers at each end
held in position by a spacer tube and washers.
Countershaft gear cluster end thrust is taken by a
single stationary, bronze faced thrust washer at
the front and by a rotating bronze washer and a
stationary steel washer at the rear.
Separate shift shafts with integral cams on the
inside and actuating levers on the outside, operate
the low and reverse and second and high gears
through forks and an interlock arrangement com-
mon to both shafts. Separate rubber mounted rods
connect the outer shift shaft levers to the levers on
the transmission control
The transmission is mounted at the front on the
clutch housing with four bolts passing through
lugs on the transmission case from the rear into
the clutch housing. This simplifies transmission
removal and replacement since the clutch hous-
ing and floor cover do not have to be disturbed.
The main drive gear be a r i n g retainer posi-
tions the transmission in a machined locating hole
in the clutch housing.
Breathing or venting is through a small open-
ing in the front of the cover and two holes in the
rear of the gasket, which is held away from the
cover at the center by a depression stamped in the
cover.
REMOVAL
1. Drain transmission lubricant.
2. Disconnect the universal joint at the rear axle
companion flange, push propeller shaft f o r
ward to release bearing cups from seats in
companion flange, then pull propeller shaft
