7200 922 012 Compressor Crankshaft for Detroit Diesel

What does a compressor crankshaft do?

This compressor crankshaft serves as a critical component within the air brake compressor system, facilitating the conversion of engine rotary motion into the reciprocating motion required for the compression stroke. Manufactured with heavy-duty grade materials, it is engineered to withstand the intense pressures and thermal cycles found in commercial air brake systems.

Vehicle and engine compatibility

This specific crankshaft is designed for use in Detroit Diesel Series 60 engines. It is compatible with various heavy commercial vehicle models including Freightliner (Argosy, Cascadia, Century Class, Classic XL, FLD120, Coronado, Columbia), Kenworth (T600, T800, W900), International (9200, 9400), Western Star (4964, 4900), Sterling (AT9500, A9500, LT9500), and Peterbilt (378, 379) trucks. It also fits Bendix systems.

Installation and maintenance

When performing maintenance or an overhaul, technicians should inspect the crankshaft for any signs of scoring or uneven wear. Proper installation is vital to ensure smooth rotation and prevent premature failure of the connecting rod bearings or seals. Checking the crankshaft alignment during assembly helps maintain long-term air pressure stability.

Troubleshooting and selection

Regular inspection of the crankshaft and its supporting bearings can help prevent sudden air pressure loss in the braking system. Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
