1698678 Volvo FM9 Compressor Connecting Rod

What does a connecting rod do?

This connecting rod serves as the vital link within the air brake compressor, joining the crankshaft to the piston to convert rotary motion into the necessary compression stroke. Manufactured from high-strength components, it is designed to withstand the intense mechanical stresses found in heavy commercial vehicle pneumatic systems.

Compatible Volvo FM9 models

This specific component is compatible with Volvo FM9 models, including the FM 9/260, FM 9/340, FM 9/380, and FM 9/300. It ensures precise movement within the compressor assembly to maintain consistent air output for the braking system.

Installation and maintenance

When replacing this part, technicians should verify the bearing clearances and ensure the piston assembly is properly lubricated. Proper installation is critical to maintaining the air output capacity and preventing premature wear of the crankshaft or piston surfaces.

Troubleshooting guidance

If you notice irregular air pressure or unusual mechanical noise from the compressor, inspecting this rod for wear is recommended. Consult your authorized distributor for more information.
