Typical example
Charging alternator group
(1) 562-7524 V-BeltIn the event of a failure, replace the former 439-7575 V-Belt with the new 562-7524 V-Belt (1).The new V-belt (1) has a short length to help increase the clearance between the belt and the water pipeline. This prevents the interference of the belt with the pipe. The new design may also increase the service life of the V-belt.
