Polyurethane bumpers of the shock absorber
The crankshaft damper pulley is designed to dampen the impulses of the mechanical impact of the engine at the moment of start-up, as well as to cushion the crankshaft during cyclic loads. It is the elastic layer between the metal parts of the pulley that performs this function, therefore it is exposed to enormous loads. And if we take into account temperature changes and the influence of aggressive auto chemicals, it becomes clear that the elastic element made of rubber will not last long. Unexpected damage to the rubber part can lead to the complete destruction of the car.
The original damper pulley is scheduled to be replaced every 100-120 thousand km. This creates difficulties both with the dismantling of the old tightly fitted pulley and when installing a new one, because it is necessary to maintain alignment.
Can such repairs be done less often? Yes, if you buy a polyurethane crankshaft pulley, not a rubber one.
Advantages of polyurethane:
- elasticity and strength are 2-2.5 times higher than that of rubber;
- resistance to abrasives;
- inertness to aggressive substances;
- stability of properties both at low temperatures and in the heat of 40⁰С.
