Ball bearing crankshaft -BGM PRO 613912 C3- (25x62x12mm) 9 balls -machined for Vespa Wideframe VM, VN, etc

BGM Pro special crankshaft bearing with narrow bearing shoulder width for Vespa Wideframe engines

These bearings should be used if the high-quality shaft seals from Corteco are to be installed at the same time. The Corteco oil seals have a greater material thickness than the previously used oil seal carriers (0.8mm instead of 0.5mm plate thickness). The narrower bearing shoulders of the BGM PRO bearings compensate for the thicker sheet metal and prevent the bearings from sitting tightly in the housing. The crankshaft can therefore be mounted as specified ex works.

TIP: Also available as a set with Corteco shaft seals (BGM1112)
