Spring tensioners are designed to tension automatically while the pivot design types can be adjusted manually. Both are used to keep tension on the engine serpentine belts so that they can drive the various engine …
Jul 13, 2020· The v-belt drive gives compactness due to the small distance between the centres of pulleys. The drive is positive because the slip between the belt and the pulley groove is negligible. Since the v-belt are made endless and there is no trouble, therefore the drive is smooth. It provides longer life, 3 to 5 years.
Worn out pulleys (if previously running a belt drive). Belt installed backwards (if previously run) first time installation printing on belt should face out. Engine not tightened properly.

4. MAXIMUM POWER TRANSMITTED BY PULLEYS The force (tension) in a pulley belt increases with torque and power. The maximum power that a pulley system can transmit is ultimately limited by the strength of the belt material. If this is a problem then more than one belt should be used to share the load.
Belt / Pulley Wear, Belt Resonance Symptoms: High radial vibration @ 2x, 3x, 4x & 5x belt rpm. Excessive belt "flap" can often be seen. Belts and/or pulleys will show excessive wear patterns, cracking, etc. if wear is the problem. Belt tension may be a problem - belts shouldn't be too loose or too tight.
