(4) Checking the Tension of the V-Belt of the
Alternator
When there is not enough tension in the V-belt, the
belt will slip making it impossible for the alternator to
generate power. Additionally, the fresh water pump will
not work causing the engine to overheat. Check the
tension of the V-belt in the following manner.
1 Press the V-belt down with your thumb at the
middle of the belt to check the tension. The give in
the V-belt should measure about 8~10 mm at the
depression.
2 To adjust the V-belt tension, loosen the set bolt and
move the alternator.
3 Replace the belt if it is damaged.
• If the V-belt tension is too tight, the belt
and the bearings of the alternator will be damaged.
• Be careful not to spill any oil on the V-belt as this will
lead to stretching and slippage.
(5) Inspecting and Replacing Anti-Corrosive
Zinc
Inspect and replace the anti-corrosive
zinc periodically.
1 Close the Kingston cock.
2 Drain the cooling seawater.
See
4.8.12)
3 Remove the plug labeled ZINC and indicated in
the diagram. Anti-corrosive zinc is on the following
parts:
If replacement of zinc is neglected and
operation is continued with a small volume of anti-
corrosive zinc, corrosion of the seawater cooling
system will occur and water leakage, parts breakage
or accidents will result.
