22306613 Connecting Rod & Piston for Volvo FM12

What does a compressor connecting rod and piston do?

The connecting rod and piston assembly is a critical component group within the air brake compressor's compression assembly. The piston compresses air inside the cylinder to generate the necessary pressure sent to the brake reservoirs, while the connecting rod transmits the crankshaft's rotary motion to the piston. These components directly influence the compressor's air output, oil consumption, and overall running noise.

Compatible Volvo FM12 models

This specific assembly is compatible with Volvo FM12 models, including various configurations such as the FM 12H/340, FM 12H/420, and FM 12/380. It is engineered to meet the rigorous demands of heavy commercial vehicle applications, ensuring stable pneumatic performance during continuous operation.

Installation and maintenance guidance

During an overhaul, renewing the piston and rings together is the preferred approach to ensure optimal compression. Technicians should inspect the connecting rod and piston for signs of excessive wear or scoring during every maintenance interval to prevent system failure. Consult your authorized distributor to ensure correct fitment.

Troubleshooting and selection

Maintaining high-strength components helps prevent oil consumption issues and ensures consistent air delivery for the braking system.
