Repair Operations Removal from Chassis
In removing the transmission from the chassis, first remove the
speedometer cable from the torque ball retainer and the hand brake
lever from the frame. Remove the cap screws holding the ball collar
and slip the ball and the collar back on the propeller shaft.
Remove the nuts from the universal joint ring and split the universal
joint. Remove the two top transmission to flywheel housing cap
screws and insert the two transmission guide pins in these holes.
Remove the flywheel underpan and remove the two lower transmission
to flywheel housing cap screws.
Remove the bolts holding the rear of trans-mission to the frame.
Remove the nuts holding the cross member to the universal joint
ball retainer and remove this part.
Slide the transmission straight back on the guide pins until the
main drive gear shaft is free of the splines in the clutch disc.
The use of the two guide pins during this operation will support
the transmission and prevent damage to the clutch disc through
springing. Remove the transmission.
48Disassembly of Transmission
After the transmission has been removed from the chassis, place
it in the bench vise as shown in Fig. 113.
Fig. 113-Method of Holding Transmission in Vise
Remove the transmission cover, interlock plate, shifter rails and
forks. Place the trans-mission in two gears to lock and keep the
gears from turning.
Remove the speedometer driven gear and shaft and the cap screw
holding the front universal joint yoke to the end of the spline
shaft with a special
