5.7.8 Adjustments and replacement of V-Belt
Two B type V belts used to drive the fresh water pump and the charging alternator.
Refer Fig. 5.12 Check the belt tension regularly; do neccessary adjustments if
required. If the belt tension is incorrect, it will lead to various troubles like high
water, poor charging of battery etc. While checking, if the belt is exible by more
than 10 mm (When applying a strong force by thumb - refer Fig. 5.13) the belt
needs adjustment. The belt tension can be adjusted from the alternator mounting
support (refer Fig. 5.14) Replace the belt(s) if any damage (peel off, crack, rib
crank or wear etc.) is noticed. Refer periodic maintenance for belt replacement
interval.
