3.

Determine the thickness of the shim using the following procedure, accounting for the axial clearance
between 0 and 0.06 mm (0.0024 In).

a.

Permanent shim = (X2 - X1) - axial clearance.

b.

Example:

• X1 = 226.59 mm (8.9208 In).
• X2 = 227.56 mm (8.959 In).
• Permanent shim = (227.56 - 226.59) = 0.97 mm (0.038 In).

Given that shims vary by 0.040 mm (0.0002 In), in this example, it is necessary to use the 0.096 mm
(0.078 In) shim in the set.

Inspection

INFOID:0000000010428790

INPUT SHAFT 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.

Disassembly

INFOID:0000000010428792

1.

Remove:

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

2.

Remove the fourth, fifth and sixth gear assembly with a press,
applying pressure under the fourth gear with an extractor.

3.

Remove the gears - hubs assembly with a press, applying pres-
sure under the reverse gear using component (A)  of the tool
[SST: KV32910340 (Bvi.1683)].

Assembly

INFOID:0000000010428793

1.

Refit the reverse gear (1) and the ring (2) using a press and
component D of the tool [SST: KV32910340 (Bvi. 1683)], posi-
tioning the lubrication holes at 90

°

 in relation to those of the

shaft.

2.

Apply a final pressure of 2.5 tons.

MAINSHAFT AND GEAR

3.

Lubricate and position the needle bearing (1) , the thrust needle
bearing (2) and the first idle gear (3) fitted with its synchroniser
ring.

4.

Refit the first-second gear selector rod (4) using a press and
component (C) of the tool [SST: KV32910340 (Bvi. 1683)], (large
hub offset on second gear side, selector rod offset on first gear
side).

5.

Align and engage the notches on the synchroniser ring with
those on the hub.

6.

Refit the ring (5) using a press and component (D) of the tool
[SST: KV32910340 (Bvi. 1683)], positioning the lubrication holes
at 90

°

 in relation to those of the shaft.

7.

Apply a final pressure of 2.5 tons.

8.

Lubricate and position the needle bearing (1) and the second
idle gear (2) with its synchroniser ring.

9.

Refit the third fixed gear (4) using a press and component (D) of
the tool [SST: KV32910340 (Bvi. 1683)].

Intermediate adjustment of the output shaft

1.

Position the spacer (1) .

2.

Measure the distance (X1) between the end of the fixed gear of
the shaft and the end of the spacer in order to determine the
thickness of the permanent shim.

3.

Given that the nominal value is 173.90 

±

 0.05 mm (6.846 

±

 0.002 In)

a.

Use the following procedure:

• Permanent shim = 173.90 - X1.

b.

Example:
X1 = 173.23 mm (0.820 In)
Permanent shim = 173.90 - 173.23 = 0.67 mm (0.0264 In)
Given that shims vary by 0.08 mm (0.003), in this example it is necessary to use the 0.68 mm (0.0268 In)
shim in the set.
