8.
Isolate the electrical supply to the engine. Remove
the guards.
9.
Loosen bolts (5) and loosen the locknut (4).
10.
Rotate the rod (3) to achieve a final tension of
62 N (14 lb). The total deflection should not
exceed 16 mm (0.63 inch).
11.
Tighten the locknut (4) to a torque of 120 N·m
(88.5 lb ft). Tighten bolts (5) securely.
12.
Restore the electrical supply to the engine. Install
the guards.

To
maximize
the
engine
performance,
inspect
the
belts
for
wear
and
for
cracking.
Replace
belts
that
are
worn
or
damaged.
To
check
accurately
the
belt
tension,
a
suitable
gauge
should
be
used.

Typical example
2.
Visible inspect fan guards for ware or damage.
Repair as necessary. Remove the fan guards (1).
3.
Inspect the belts for cracks, splits, glazing, grease,
displacement of the cord and evidence of fluid
contamination. If necessary, replace the belts,
refer to “Replace” for more information.
Adjust
1.
Ensure that the electrical supply to the engine is
isolated.
2.
Using a suitable belt tensioning tool, check the
tension of the fan belts. the belt tension should be
checked in the middle point between the two
pulleys.
• New belt tension should be set to 49 N (11. lb)
• Belt tension range should be from 31 N to 49 N
(6.9 lb to 11 lb)
• Belt deflection should be 4.2 mm (0.165 inch)

3.
Each belt must be checked.
4.
Loosen nuts (4) on fan adjuster plate (5). Loosen
lock nut (3).
5.
Turning bolt (2) counter-clockwise will adjust fan
pulley (6) and loosen the fan belts (7).
