Crankshaft Pulley

HOW TO DETECT THE CRANKSHAFT PULLEY FAILURE

The crankshaft pulley examination is advised to be performed every 60,000 kilometers. Cracking or warping of the elastic element, splitting of rubber and metal parts, cracks on the hub or near the fastening holes, multicolored stains on the outer housing surface indicate that the part needs replacement.

The absence of visible faults cannot always guarantee that the part is in good order. To check if it is working, you must mark the pulley from center to edge, then start the engine and switch on various equipment to provide maximum load on the belt drive. Then you should shut down the engine and see if the marks match.
