Typical example
2. Loosen bolts (5) and loosen the locknut (4).
3. Rotate the rod (3) to achieve the correct tension of
belts (1). Refer to "Inspection" for the correct
specification.
4. Tighten the locknut (4) to a torque of 120 N·m
(88.5 lb ft). Tighten bolts (5) securely.
5. Ensure that the electrical supply to the engine is
isolated. Install the guards.
Replacement
Note: Fan drive belts must be replaced as a set. Do
not replace individual belts.

3. Rotate the rod (3) until the pulley (2) is toward the
center of the engine.
4. Remove the belts (1).
Procedure to Apply the Grease to Fan
Drive Assembly and Jockey Pulley
1. Use Shell Alvania RL3 or Shell Gadus S2 V100 3
and apply 8 to 10 grams of grease to the bearings.
Note: Each grease gun will be different, so an
exercise to determine what the actual gun that is
used is delivering will be required. The exercise will
ascertain that the correct mass is being used. If a
digital delivery system is being used, the grams
requirement can be converted to cubic centimeters.
For example, 8 to 10 g is equivalent to 40 cc.
2. Use a suitable low-pressure grease gun to pump in
the recommended grease.
3. Slowly add the grease to minimize an excessive
pressure build-up in the grease cavities.
4. If excessive amounts of grease are pumped into
the bearing housing and the old, used grease is
not being purged, stop the operation. Check for
hardened grease blocking the passages.
