New replacement idler gear for all A+ gearboxes. The A+ idler gear uses .0875" shafts and 37 teeth. These are the most prone to wear in the transverse A-series drop gear system as they constantly shuffle acceleration and decceleration shock between the engine and gearbox, so it is essential that the teeth as well as bearings are in tip-top shape.
 
Not for automatic gearboxes.
