FAQ

Q1: How do I verify this thrust washer fits my engine?

A: The most reliable way is to check the part number on your original thrust washer. It should match WP4G95E221. Additionally, ensure your engine is a Weichai WP4G series. If you are unsure, please contact us with your engine model and serial number for verification.

Q2: What are the symptoms of a worn thrust washer?

A: A worn or failed thrust washer can cause excessive crankshaft end-play. Symptoms may include a noticeable knocking or thudding sound from the engine, especially during clutch engagement or gear changes in manual transmissions, and potential vibration. If you suspect failure, immediate inspection is recommended to prevent damage to the crankshaft and engine block.

Q3: Is installation a DIY task?

A: Replacing a thrust washer is an advanced repair that requires engine disassembly (removing the oil pan and possibly the crankshaft). It is strongly recommended to have this work performed by a certified diesel mechanic. Proper measurement of crankshaft end-play is critical after installation to ensure correct clearance.
