7200 851 014 Compressor Crankshaft for Heavy Duty

What does a compressor crankshaft do?

The compressor crankshaft is a critical component that transfers rotary motion from the engine to the piston through the connecting rod, directly determining the compressor's compression performance. This part is essential for maintaining stable air pressure within the pneumatic braking system of heavy commercial vehicles.

Compatible vehicles and engines

This crankshaft is fitted to various heavy commercial vehicle models including Kenworth, Peterbilt, Freightliner, and Volvo, specifically supporting engines such as Cummins ISL9, ISC, and ISB. It is also used in buses from brands like Blue Bird, International, and Thomas Built Buses to ensure reliable braking performance.

Installation and maintenance

When performing an overhaul, technicians should verify that the crankshaft meets exact dimensional tolerances to prevent vibration or oil leakage. Installation requires careful alignment with the connecting rod and bearing assembly to ensure smooth operation under high pressure. Check the compatibility list before replacement.

Troubleshooting and selection

If the compressor exhibits unusual noise or a drop in air pressure, inspecting the crankshaft and associated bearings is a recommended troubleshooting step. This component works in tandem with WABCO systems to maintain system integrity.
