OVERHAUL
Remote gear change - Type D gearbox - Refit
1. Apply sealant, Part No. STC 3254 to mating
surfaces of extension housing and remote gear
change housing.
2. Position remote gear change housing on
extension housing. Ensure that gear lever ball
is correctly located.
3. Fit bolts and tighten to 25 Nm (18 lbf.ft).
Bias spring adjustment - Type A gearbox
NOTE: The purpose of this adjustment is
to set both bolts so that the bias spring
legs apply equal pressure on both ends of
the gear lever cross pin when third or fourth gear
is engaged. This will ensure that when the lever
is in neutral, the gear change mechanism is
automatically aligned for third or fourth gear.
1. Select third or fourth gear.
2. Adjust the two adjusting screws until both legs
of the spring are approximately 0.5 mm (0.02
in) clear of the cross pin in the gear lever.
3. Apply a light load to the gear lever in a left
hand direction and adjust the right hand
adjusting screw downward until the right hand
spring leg just makes contact with the cross
pin.
4. Repeat the same procedure for the left hand
adjusting screw.
5. Lower both adjusting screws equal amounts
until the radial play is just eliminated.
6. Tighten locknuts.
7. Return gear lever to neutral position and rock
across the gate several times. The gear lever
should return to the third and fourth gate.
