- Inspect the scavenge tube
(54) for damage and clogging.
- Install the scavenge tube
seal (53) into the case.
- Install the scavenge tube (54) into the scavenge tube seals (53)
located in the case and in the driven sprocket support. Tap the scavenge tube (54)
lightly with a plastic hammer to ensure a tight fit in both seals.
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.
- Install the scavenge
tube bolt (15).
Tighten
Tighten the bolt to 8-14 N·m (6-10 lb ft).
- Inspect the case to case
extension seal (126).
- Inspect the case extension mating surface for damage.
- Install the following
parts:
• | The selective washer (133) |
• | The thrust washer (132) |
• | The case extension seal (126) |
• | The case extension (134) |
- Apply pipe thread sealant
GM P/N 12346004 to bolt threads before installation. Install the case extension
bolts (128, 129).
- Hand tighten the bolts (128, 129) until the case extension (134)
is seated onto the case.
- Install the long J 25025-7A
and the J 8001
.
- Position the dial indicator with the stem contacting the output
shaft (112). Set the dial indicator to zero.
- Insert the J 28585
through the vehicle speed sensor bore and lift the speed sensor rotor
for measurement. Protect the bore with a piece of wood or a suitable piece
of plastic.
- Proper end play clearance is 0.15-0.65 mm (0.006-0.026 in).
- Record the measured specification and, if necessary, adjust the
clearance with the proper thickness selective thrust washer and reassemble.
Refer to step 3.
- Remove the dial indicator set and the post.

- Install the stud (127).
Tighten
• | Tighten the bolt (128) and the stud (127) to 50-55 N·m
(37-40 lb ft). |
• | Tighten the bolt (129) to 20-27 N·m
(15-20 lb ft). |
