POLINI CRANKSHAFT REPLACEMENT KIT: HIGH SPEED RANGE

Every time the replacement of some engine parts is needed, it is compulsory to replace both the oil seals and the bearings since they support the crankshaft and they work at high rpm. This is why Polini Motori has designed a complete replacement kit for the best crankshaft overhauling of the most popular Vespa Scooters and moped models. The Polini kit includes the oil seals and bearings and they are perfectly interchangeable with the original ones. The crankshaft bearings are made of C4 riveted steel. The oil seals are made of FKM (Fluorocarbon rubber) to better resist to the highest termic stress. The seal lip is made of PTFE (Polytetrafluoroethylene); this feature makes them more durable than the standard original ones, giving them a smaller friction coefficient thus granting less heat dispersions caused by the friction and at the same time maintaining lower temperatures. Polini crankshaft replacement kit will fit the original engines but it can be used on the tuned-up ones also.
