Grade A – perfect repair Product description
The
SIP-BFA crankcases
are equipped with other kinds of bearings and shaft oil seals than original Vespa crankcases. This is mostly due to the substantially more stable crankshaft concept. It is guided on both sides by very generously dimensioned bearings. The fixed bearing is located in the smaller casing half, the roller bearing in the larger section. This led to the shaft oil seal having to be slightly repositioned.
The gearbox bearings remain identical to those compatible with original Vespa PX engines, although the kickstarter shaft is equipped with two extra needle type bearings. It is also kept from leaking with a proper shaft oil seal, instead of the fragile ‘O’-ring found on original engines. We naturally have all these bearings and shaft oil seals available from our shop, separately or in economic sets.

?C TIP: We recommend the ordering of the complete bearing and oil seal sets, whether assembling a new engine or servicing an existing one. Engines that perform on this level deserve completely functional bearings and seals!
