33T Steel Idler Gear, chassis spare part

This 33T steel idler gear is a dedicated spare part for selected RC chassis and brings a precise transmission component into repair and maintenance work. Supplied as 1 piece, it is intended for use with the BB-01, TD2, TD4 and XV-01 chassis, where the stated 33-tooth specification matches the required internal gear position. The part is used in place of MA27, identified in the source data as the green gear in the reference image. That direct replacement note matters during servicing, because it points to the exact gear position rather than leaving fitment to guesswork. The steel construction suits a mechanical role inside the drivetrain, while the compact gear form with central hub and slot reflects its function as a transmission component rather than an external accessory. For chassis owners keeping a running model in service, a clearly specified spare like this helps restore the intended internal setup with the named tooth count and platform compatibility. It fits naturally into workshop tasks such as replacing a worn transmission gear during a rebuild, refreshing a used chassis, or keeping a matching spare on hand for BB-01, TD2, TD4 or XV-01 maintenance. The single-piece format keeps the scope clear when one exact idler gear is needed.
