Compatible drive gear for B-MAX4 chassis

The Yokomo BM-504 drive gear supplied with a header card is intended as a compatible replacement for the B-MAX4 input shaft. Supplied in twos, it supports straightforward part swaps during repairs or routine upkeep.

The component mounts to the input shaft and passes motion through the gearbox train; the header card assists with stock control and part recognition. Fitting the gear requires basic gearbox access to remove the existing unit and install the new gear while preserving any original shims and correct orientation.

This item is ideal when worn teeth are identified or when keeping matched spare gears improves readiness for longer running sessions or systematic servicing routines.
