1997 ISUZU TFS SERIES lock

4B-22 REAR AXLE
Important Operations
1. Ring Gear
Take care not to damage the ring gear or the differential case
when removing the ring gear. Never try to wedge a tool
between the two faces.
2. Lock Pin
Drive out the pinion shaft lock pin with a long drift punch. It
may be necessary to first remove the stakes in the lock pin with
a 5 mm drill.
3. Cross Pin
(1) Check the amount of backlash before removal.
Backlash mm(in)
194 mm 0.03 - 0.08 (0.001 - 0.003)
220 mm 0.13 - 0.18 (0.005-0.007)
(2) Remove the cross pin with a brass drift punch, and take out
the pinion gears, side gears, thrust block and thrust
washers from the differential cage.

5. Pinion gear
(1) Clamp special tool (side gear holder) into a vice. Set the
LSD assembly.
Holder : 5-8840-2010-0
(J-36563)
(2) Set special tools (side pinion expanders and pinion rotator)
to the LSD.
Expander : 5-8840-2011-0
(J-36564)
Rotor : 5-8840-2012-0
(J-36565)
(3) Set special tool (cage lock bar) through a ring gear fixing
hole to a vice.
Then rotate side pinion expanders with a wrench one half to
one full turn to provide backlash between the side and
pinion gears.
Bar : 5-8840-2013-0
(J-36566)
(4) W ith a wrench, rotate special tool (pinion rotator) to remove
the pinion gear and the pinion washer.

(3) Set special tool (cage lock bar) through a ring gear fixing
hole to a vice.
Then rotate side pinion expanders with a wrench one half to
one full turn to provide proper clearance to install the pinion
gears.
Bar : 5-8840-2013-0
(J-36566)
(4) Attach the pinion gears and washers in the proper order to
the left and right hand side of the differential cage.
(5) W ith a wrench, turn special tool (pinion rotator) to align the
pinion gear and washer holes with the pinion shaft holes on
the differential cage.
Confirmation of operation
Using the side gear holder, measure the starting of the side
gear.
