Bearings and Crankshaft seals Minarelli AM6 Polini

Bearings and crankshaft seals Polini for Minarelli AM6.

This Polini crankshaft bearing and seal kit is designed for maintenance or rebuilding of the engine crankcase on Minarelli AM6 50 geared engines. Developed to replace worn original components, it allows the crankshaft supports to be renewed and proper sealing to be restored in the crankcase area.

It is recommended to replace the bearings and seals during a complete engine rebuild or when symptoms such as play in the crankshaft, abnormal metallic noises, or possible air leaks caused by seal wear are detected. A loss of sealing in this area can affect carburetion and the overall operation of the engine.

The kit includes bearings with C4 internal clearance tolerance and a riveted steel cage, suitable for operation in engines subjected to high rotational speeds. The seals made of PTFE and FKM offer resistance to fuels, oils, and demanding operating temperatures, helping to maintain the sealing of the assembly.
