478777 Volvo F7 TD70 Air Brake Compressor Gear

What does a compressor gear do?

The compressor gear is a vital drive component that enables the air brake compressor to receive rotation directly from the engine. It mounts onto the compressor crankshaft end or drive flange and meshes with the engine's timing gear train to transfer rotary motion to the piston assembly, which is essential for producing necessary compressed air.

Vehicle and engine compatibility

This specific part is compatible with Volvo F7 trucks equipped with TD70 engines. It functions within the air brake system to ensure consistent pressure delivery for heavy commercial vehicle braking performance.

Installation and maintenance

For workshop technicians, renewing the gear set is often a sufficient solution when wear is detected in the drive mechanism. When selecting a replacement, it is crucial to verify the tooth profile and connection type to ensure proper meshing with the timing gear train.

Troubleshooting and selection

Regular inspection of the drive components can prevent system-wide failures caused by insufficient air pressure. Consult your authorized distributor.
