4.

Position the selected shim.

5.

Refit the fourth (1) and fifth (2) fixed gear using a press and
component (D) of the tool [SST: KV32910340 (Bvi. 1683)].

6.

Position the spacer (3) and the sixth fixed gear (4).

Output shaft end float adjustment

1.

The output shaft end float must be 0.01 mm (0.0004 In).

2.

Measure the distance (X2) between the end of the shaft and the
sixth gear, in order to determine the thickness of the shim (1).

3.

Example:

• X2 = 1.30 mm (0.051 In)
• Shim (1) = 1.30 - 0.01 = 1.29 mm (0.0508 In)

Refit the bearing (2) using component (C) of [SST: KV32910340
(Bvi. 1683)] and a press.

4.

Determine the thickness of the half shims with a feeler gauge
(1).

5.

Refit:

• the two half shims (1),
• the closure washer (2),
• the lock ring (3).

MAINSHAFT AND GEAR

When checking, make sure that you pay particular attention to the
appearance of the teeth, especially that of the chamfers and claws.

Check that:

• the teeth (1) are not broken or chipped,
• the dogs (2) are not broken, chipped or worn,.
• the friction cone (3) shows no sign of scratches or blue stains,
• the inner wall (4) shows no sign of sticking or wear.

SYNCHRONIZER HUB

Check:

• that the selector rod slides onto the hub easily,
• that the collets (1) are in good condition.

SYNCHROMESH RING

Check that the dog teeth (1) show no sign of wear or any fractures.
To check that the synchroniser ring is working correctly, push the ring
on the friction cone and rotate (2) : the ring should not turn. Other-
wise, replace the synchroniser ring.

BEARING

Make sure the bearings (1) are rotating properly.
If a bearing rotates unevenly or noisily, it must be replaced.

Adjustment

INFOID:0000000010471529

ADJUSTMENT OPERATION FOR THE AXIAL CLEARANCE OF THE REVERSE GEAR INTERMEDIATE SHAFT

1.

Measure the distance (X1) between the end of the reverse gear
pinion and the joint face with the reverse gear shaft in place.

2.

Remove the reverse gear shaft.

3.

Measure the distance (X2) between the mechanism housing
joint face and the bearing face that takes the permanent shim.

4.

Determine the thickness of the shim using the following procedure, accounting for the axial clearance
between 0.04 mm(0.002In) and 0.14 mm (0.006 In).

a.

Adjusting shim = (X2 - X1) - axial clearance

b.

Example:

• X1 = 58.29 mm (2.295 In)
• X2 = 60.60 mm (2.386 In)
• Permanent shim = (60.60 - 58.29) - 0.04 = 2.27 mm (0.0894 In).

Given that shims vary by 0.080 mm (0.003 In), in this example, it is necessary to use the 2.24 mm (0.088
In) shim in the set.
