478777 Volvo D16 Compressor Gear Replacement

What does a compressor gear do?

This compressor gear serves as the critical drive component that allows the air brake compressor to receive rotation directly from the engine. By meshing with the engine's timing gear train, it transfers the necessary rotary motion to the compressor crankshaft, which subsequently drives the piston assembly to generate compressed air for the braking system.

Compatibility with Volvo engines

This specific gear is designed for use in Volvo TAMD162 D16 engines. It provides a reliable solution for maintaining air pressure stability in heavy commercial vehicle pneumatic systems. For precise fitment, always verify the tooth profile and hub connection against the existing unit.

Installation and maintenance guidance

When performing maintenance or repairs, technicians should inspect the gear teeth for signs of uneven wear or pitting. Proper installation ensures that the compressor speed and air output remain within the required technical parameters. It is recommended to follow the service manual for specific torque and clearance values during assembly.

Troubleshooting and selection

Selecting a high-strength component helps prevent sudden loss of air pressure and ensures long-term reliability in demanding heavy-duty operating environments.

OE cross-reference
