BGM Original Vespa Clutch Shim (34.5x15.5x3.3mm) PX, T5, Rally, Cosa, Sprint
The washer between crankshaft and clutch has three very important functions:
- To create a controlled preload between the crankshaft and the ball bearing
- To provide a sliding bearing surface for the clutch pinion during clutch operation
- To create the correct distance between the clutch and the bearing so that the gearing is aligned with the primary wheel and the correct distance to the clutch cover is maintained.
The BGM Shim is much better made than the Piaggio Original Component allowing it to last longer than other shims on the market.
