POLINI 282.0006 bearing and oil seal overhaul kit for 20 mm cone crankshaft for VESPA 50 125 SPECIAL PK XL NLR 125 ET3 ETS PK PRIMAVERA ET3 XL APE 50 FL FL2 FL3 RST MIX Bearing 17-47-14 C4 STEEL - NAILED / C4 20-47-14 C4 STEEL - NAILED / C4 Oil seal 20-32-7 PTFE + FKM 22.7-47-7/7.5 PTFE + FKM When overhauling an engine, it is mandatory to replace both the oil seals and the main bearings as they support the crankshaft and rotate at high speeds. This is why, for a better and specific overhaul of the crankshaft for the most popular scooter, Vespa and moped models, Polini has created a special kit. The Polini kit is complete with oil seals and bearings and is perfectly interchangeable with the original spare parts. The bearings for the crankshaft are made of steel with a C4 nailed cage. The oil seals are made of FKM (fluorocarbon rubber) to resist the highest thermal stress, they have the sealing lip covered in PTFE (polytetrafluoroethylene); this feature, in addition to ensuring a longer life compared to the standard ones, means that they have a significantly lower friction coefficient, thus guaranteeing less dispersion and at the same time maintaining lower temperatures. The Polini crankshaft overhaul kit is perfect for the original engines but also adapts perfectly to the more powerful engines.
