- Install the J 8001
to the differential carrier with the
dial indicator plunger against a ring gear tooth.
- Hold the pinion gear stationary.
- Move the ring gear (1) back and forth as far as it will
travel without turning the pinion gear.
- Observe the J 8001
while moving the ring gear back and forth as previously described.
Differential backlash should be within 0.013 to 0.018 mm (0.005 to
0.007 in).
Important: In order to preserve the differential side bearing preload, any time
a side bearing adjuster is loosened, the other adjuster MUST be tightened
the same amount. The last motion of this adjustment must be in a tightening
direction.
- Correct the specifications by following the directions below:
Above Specification
| • | Loosen the left side bearing adjuster approximately ¼ turn. |
| • | Tighten the right side bearing (1) adjuster approximately
¼ turn using the J 37760
. |
| • | This procedure moves the ring gear close to the pinion gear in order
to cause a tighter mesh and less backlash. |
Below Specification
| • | Loosen the right side bearing adjuster approximately ¼ turn. |
| • | Tighten the left side bearing adjuster approximately ¼ turn
using the J 37760
. |
| • | This procedure moves the ring gear away from the pinion gear in order
to cause a looser mesh and more backlash. |
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Continue with the
adjustment of specifications until the most accurate differential backlash
is obtained.
Tighten
Tighten the differential side bearing cap bolts to 60 N·m
(44 lb ft).
- Install both side bearing lock plates; secure with two bolts.
Tighten
Tighten both of the side bearing lock plate bolts to 13 N·m
(10 lb ft).
