8000 704 001 Connecting Rod & Piston for Air Brake Compressors

What does a compressor connecting rod and piston do?

The compressor connecting rod and piston assembly serves as the mechanical core of the pneumatic brake compressor, directly determining air output, oil consumption, and running noise. The connecting rod transmits the crankshaft's rotary motion to the piston, which then compresses air within the cylinder to generate the necessary pressure for the vehicle's brake reservoirs.

Compatible vehicles and engines

These components are widely used in heavy commercial vehicles including Freightliner, International, Peterbilt, Kenworth, Western Star, and Mack trucks. They are specifically designed to work with Caterpillar C15, C16, and 3176 engines. This assembly is also compatible with Bendix systems.

Installation and maintenance

For professional technicians performing an overhaul, renewing the piston and rings together is the recommended approach to ensure an air-tight seal. When inspecting for replacement, check for excessive oil consumption or unusual running noise in the compressor unit. Consult your authorized distributor to verify specific fitment.

Troubleshooting guidance

Maintaining these high-strength components is vital for the reliability of the pneumatic braking system in heavy-duty trucks and construction machinery.
