This sale is for ONE bearing. Replacement bearing for the end of the mainshaft where it fits into the 1st motion gear (4th) on 4 synchro A series gearboxes only. Essential to replace this bearing when rebuilding the gearbox due to their small size they suffer from failure more frequently than the later gearboxes which have larger bearings. Note does not fit 3 synchro or A+ gearboxes.
