Cooling Systems
FAN-COOLED MODELS
On Z 440 models, the engine is cooled by air
passing over the engine's fins on the cylinders
and cylinder heads. The air is circulated by a fan.
Fan Belt Removal/Installation
Refer to Figure 1 during this procedure.
1. Remove the fan intake cover.
2. Remove the recoil starter assembly (A, Fig-
ure 2).
3. Remove the nut (B, Figure 2) and washers.
Some of the flat washers may be adjusting shims.
4. Withdraw the outer pulley half. Do not lose
shims which may be located between the pulley
halves.
5. Lift the belt from the lower pulley (Figure 3).
6. Inspect the belt carefully. Install a new belt if
its condition is questionable.
7. When installing, install the belt in the groove
of the lower pulley and position the belt against
the upper pulley inner half.
NOTE
If
a new belt is installed, position all the
shims between the pulley halves. If the
old belt is installed, position the shims in
the same place they were originally in-
stalled.
8. Install the outer pulley half.
9. Install any shims not needed between the
pulley halves outside the pulley. These shims
may be required for later adjustment.
10. Install the flat washer, lockwasher and pul-
ley retaining nut. Tighten the nut to 25-40 N.m
(18-30 ft.-lb.) torque.
NOTE
Turn the pulleys while tightening the re-
taining nut to prevent pinching the belt
between the pulley halves.
11. Check the belt tension by pressing the belt
(20, Figure 1) with your finger at about midpoint
between the pulleys. The observed amount of
deflection should be no more than 6 mm ( 114 in.).
