This crankshaft is a critical component of the air compressor, converting rotational motion into the reciprocating movement required for compression. Manufactured from high-strength forged steel, it provides superior durability and resistance to fatigue compared to a worn or cracked crankshaft. Operators may observe a significant drop in air pressure, unusual noises emanating from the compressor unit, or a complete failure of the air system to build pressure.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing crankshaft may initially manifest as increased noise and vibration from the air compressor unit. If ignored, the wear can progress to cause significant pressure loss, leading to unreliable air brakes and auxiliary systems. Continued operation risks complete compressor seizure, potentially disabling the vehicle's air supply.
Ensure the crankshaft journals are meticulously cleaned and lubricated with assembly oil before installation to prevent initial wear. Never reuse old connecting rod bolts; always use new ones with the correct torque specification.
Inspect the connecting rod bearings and cylinder assembly for wear or scoring when replacing the air compressor crankshaft.
