22306613 Connecting Rod & Piston for Volvo B9R D9B

What does a compressor connecting rod and piston do?

The compressor connecting rod and piston assembly is a vital part of the air brake compressor mechanism. The connecting rod transmits the crankshaft's rotary motion to the piston, which in turn compresses air inside the cylinder to generate the necessary pressure for the pneumatic brake system. This component group directly influences the compressor's air output, oil consumption, and overall running noise.

Vehicle compatibility and engine fitment

This specific assembly is designed for Volvo B9R vehicles equipped with D9B engines. It provides a reliable replacement for worn or damaged internal compressor components, ensuring the pneumatic system maintains required pressure levels for heavy commercial vehicle safety. It is compatible with Volvo OE specifications to ensure precise fitment within the engine's compression assembly.

Installation and maintenance guidance

During maintenance or an overhaul, technicians should inspect the piston rings and pin alongside the connecting rod to ensure optimal performance. Proper installation is critical to prevent excessive oil consumption or irregular air output. For professional workshop technicians, verifying the engine type and compressor model ensures a correct match during service intervals.

OE cross-reference

8000 850 005 (Compressor Connecting Rod & Piston) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 22306613.
