Casa Lambretta 46 tooth crown wheel for J50 first version

Casa Lambretta 46 tooth crown wheel for J50 first version

This is the new 46T clutch bell sprocket for Lambretta J50 cc Vers. 1 models and is also adaptable for all other J Range models. Produced exclusively for Casa Lambretta to very high standards, these are superb and a real breath of fresh air as these are always worn out when you go to overhaul or restore an engine.

There are two types of clutch sprocket crown wheel assemblies for J range and Lui Vega Cometa models, with either a bronze bush or with a needle bearing. This clutch crownwheel is for models with a needle bearing (Item: 617). This crownwheel is supplied WITH the steel bush (Item: 976) for the bearing.

This is the complete list of all possible front drive sprocket & clutch crown wheel sprocket combinations for all J-Range and Lui-Vega-Cometa models, complete with the required length chain (with 'live' product links):
