3~-Transmission
and Rear Axle
I. DESCRIPTION
The transmission, rear axle and engine are bolted
together as one unit and are located and supported in the
rear of the vehicle on three rubber mountings.
At the front, the assembly is supported by a bonded
rubber mounting between the chassis frame crossmember
and the transmission, and at the rear end, a crossmember
attached to the engine, secures it to the body through a
rubber mounting on each side.
The transmission case is closed at the front end by the
gear carrier and at the rear by the clutch housing, both of
which are attached to the case by bolts.
Separating the transmission and the differential is a
partition which serves as a mounting for the main drive and
pinion shaft bearings. In this partition there are many holes
for maintaining the same oil level in both portions of the
case.
The final drive and the differential are located in the
centre part of the transmission case.
The differential bearings are carried in two cover plates
which are secured to the case. In the rear of the case, the
clutch housing is bolted to the case. Within the housing,
and to the left, is an oil filler plug which also
serves to indicate correct oil level. At the bottom of the
clutch housing is located the transmission case oil drain
hole into which is screwed a plug incorporating a
permanent magnet.
The drive is transferred from the final drive to the rear
wheels through two open drive shafts, each incorporating a
pair of constant velocity joints, one at each end of each
drive shaft.
The reduction gear arrangement on previous models
has been discontinued.
2. ENGINE AND TRANSMISSION ASSEMBLY
TO REMOVE
When removing the transmission it is advisable to
remove the engine and the transmission as a unit. It is,

(2) Take out the rear cross panel and remove the air
cleaner with the inlet bent hose.
(3) Detach the electric leads from the generator,
ignition coil, oil pressure gauge and the carburettor.
