Checking the Fan-belt Tension
23
Checking the Fan-Belt Tension of MF Tractor :
Fan-belt being loose or overly tightened may become a reason to overheat the engine
and damage the alternator. Therefore, it is necessary to have the fan-belt tightened to
proper tension. To check the tension, pressing the longer portion of the belt (between
the alternator and crankshaft pulley as shown in the picture) with a force of approximately
10 pounds should loosen the belt 10mm or ⅜ of an inch.
In case of improper tension in the belt, loosen the alternator and adjusting link nuts, and
by pressing the alternator with the help of a lever, tighten the bolts after adjusting the
belt’s tension. Check the tension again after tightening the bolts.
Very Important :
Always use belts of correct size.
Do not use any kind of oil or grease to mount the belt.
