REMOVAL SERVICE POINTS
ACLUTCH RELEASE BEARING SEPARATION
(1) Remove the cover from the service hole in the clutch
housing.
(2) While pushing the release fork by hand in the direction
A, insert a flap-tip screwdriver between the release bearing
and the wedge collar.
Caution
Be sure to push the release fork in the direction A
before inserting a screwdriver.
(3) Separate the release bearing from the wedge collar by
prying with the screwdriver (turning the screwdriver grip
90).
NOTE
The release fork is forced to move fully in the direction
B by the return spring as soon as it is separated from
the wedge collar.
Caution
If it is hard to turn the screwdriver (to pry off the
release bearing), remove the screwdriver once and
repeat the above procedure after pushing the release
fork fully in the direction A two to three times. Forcibly
prying can cause the release bearing to be damaged.
BDRIVE SHAFT / DRIVE SHAFT
DISCONNECTION
(1) To disconnect the left-hand drive shaft, insert a lever
as shown and pry out the shaft from the transmission.
To disconnect the right-hand drive shaft, apply a lever
and a hammer as shown and lever out the shaft from
the transfer assembly using the hammer as a fulcrum.
NOTE
Remove the drive shafts with the hub and knuckle
attached.
Caution
Do not attempt to pull out the drive shaft from the
BJ in this stage since it can cause the TJ to be
damaged. Be sure to remove the drive shaft first from
the transmission side using a lever.
(2) Suspend the removed drive shaft with a wire so that
there are no sharp bends in any of the joints.
COUTPUT SHAFT REMOVAL
(1) Use the special tools (MB991612, MB990211) to remove
the output shaft.
(2) Use a shop towel to cover the transmission case not
to let foreign material get into it.
