The air compressor drive gear (or compressor gear) is part of the gear train that drives the air compressor on commercial vehicles with pneumatic braking systems. The gear meshes with the engine's auxiliary gear train to drive the compressor at the correct speed. A worn or damaged drive gear causes excessive compressor noise, reduced air output, and contamination of the gear train with metal particles.
Air compressor gear wear produces recognisable symptoms that distinguish it from other gear train failures.
Compressor drive gear replacement requires careful attention to gear backlash, end-float, and torque settings to avoid rapid repeat failure.
