1.

Remove fixation bolt, idling pulley and inner
tensor.

Distribution belt installation and tensioning

2.

Make sure that marks are aligned (Ref. A and
B) and that injection timing tool pin nr.
8130633 is correctly introduced in injection
pump pulley (Ref. C).

Note:

The belts must be stocked with the edges in a clean surface and in such way that the
folds do not have a radius lower than 50 mm. Do not fold belts in an acute angle or with
ray lower than 50mm, otherwise it may occur premature failures

.

Belt tensor

Note:

The belt tensor only needs to be removed if it is being replaced or to have access to
remove the timing housing.

Note:

It is important that belt tensioning is carefully and safely made. The following procedure
evolves the belt tensioning to assure that it keeps tensioned between each pulley.

1.

Lock engine, at TDC, positioning the pin of
the timing tool nr. 8130632 in the flywheel-
housing hole with the pin fitted in the flywheel
hole.

3.

Loosen the 3 (three) fuel injection pump
pulley fixation bolts (Ref. D), letting pulley
slightly loose to allow belt accommodation.

4.

Install distribution belt on the pulleys.

5.

Slightly press belt tensor, screwing tensor
bolt. Make sure if tensor movement is free,
that is to say, bolt slightly loosen, allowing
free movement, but, without side clearance.

6.

Install in the square among idle and tensor
pulleys, special tool nr. 8130649, which is
adjusted to attend a torque equivalent from
9 to 10 Nm.

7.

Tighten tensor bolt within 40 to 50 Nm.

8.

Tighten the 3 (three) fixation bolts of fuel
injection pump pulley, within 22 to 28 Nm.

9.

Remove special tool, fuel injection pump and
flywheel locking device.

10. Manually turn engine (2 turns) to distribute

belt tension.

11. Check engine timing.

Note:

After the torque application, it is recommended to check belt tension by the device
pitch within 130 to 160 Hz.
