7200 852 013 PACCAR MX13 Compressor Crankshaft

What does a compressor crankshaft do?

The compressor crankshaft serves as the central component in the air brake compressor, responsible for converting the engine's rotary motion into the reciprocating motion required for the compression stroke. This high-strength component is engineered to withstand high-pressure cycles and continuous operation within heavy commercial vehicle air systems.

Vehicle and engine compatibility

This crankshaft is specifically designed for use in vehicles equipped with PACCAR MX13 engines, including models from Kenworth such as the T680, W990, T660, T800, T880, and DAF CF/XF106. It is also compatible with various Peterbilt models like the 567, 389, 386, 384, 367, 579, 365, 589, 388, and 587. These parts are essential for maintaining optimal pneumatic pressure in the braking system.

Installation and maintenance

When performing maintenance or an overhaul of the air brake compressor, technicians should inspect the crankshaft and connected bearings for signs of uneven wear or scoring. Proper installation ensures that the internal piston movement remains synchronized with the engine's timing, preventing air leaks or pressure loss in the braking circuit.

System performance and selection

For systems utilizing WABCO components, ensuring exact fitment is critical to maintaining service life. Consult your authorized distributor to confirm specific application requirements.
