Gearbox Bearing 1st Motion Internal 3 Sync

Gearbox Bearing 1st Motion Internal 3 Sync

This sale is for ONE bearing. This is the bearing for the end of the mainshaft where it fits into the 1st motion gear (4th) on 3 synchro gearboxes only. Essential to replace this bearing when rebuilding the gearbox due to the small size they suffer from failure more frequently than the later gearboxes, which have larger bearings.
