4.3.8 Check V-belt tension
Too tight belt tension could damage shaft and shorten bearing life. Too loose belt tension may result in
damaging belt earlier and machine components due to overheat.
Follow the procedure below to adjust tension of fan belt and V-belt for alternator.
<Procedure>
① Adjust the tension by gradually loosening the
fastening bolt of the alternator.
② Visually check if there are any cracks or tears in
the belt.
③ Adjust the belt tension by loosening the fixing
bolt of the alternator so that the belt can deflect
0.32 to 0.45in(8 to 12 mm) when pressed at the
center of the belt with approx.22lbf (98N) force.
④ Be careful not to leave any grease or LLC on a
belt while changing it. If any such material is left,
wipe it off completely.
4.3.9 Check wiring of each part
Check each wiring for any loose connection, damage to insulating sheathed portion, disconnection, and
short-circuit.
4.3.10 Check piping of each part
Check each piping for any loose connection and also check each hose and pipe for any tear and leaks.
Depress the middle
of the belt with a
finger.
This deflection
should be 0.32
to 0.45in.
