This thrust washer is a critical engine component designed to manage axial loads and maintain proper clearance between rotating and stationary parts within the engine's crankshaft assembly. Manufactured from hardened steel with a specific bearing surface, it provides a low-friction interface, unlike a worn washer that has lost its surface integrity and may cause excessive play. Operators might notice increased engine noise, particularly a knocking sound under load, or a drop in oil pressure if this washer fails.

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.
The first indication of a failing thrust washer is often an audible knocking or rattling sound from the engine, especially when accelerating or under load. If ignored, this noise can become more pronounced, and the increased crankshaft play may lead to a noticeable drop in oil pressure. Continued operation with worn thrust washers risks severe damage to the crankshaft and main bearings.
Ensure all oil passages are clean and clear before installing new thrust washers; debris can impede lubrication and cause premature wear. Always install thrust washers in matched pairs and verify proper crankshaft end play after installation.
Inspect the crankshaft journals and main bearings for any signs of scoring or wear when replacing thrust washers.
