FAQ

Q1: How do I confirm if ME200280 fits my Mitsubishi 4M40 engine?

A: The ME200280 thrust washer is designed as a direct OEM replacement for the 4M40 engine family. However, due to variations in engine serial numbers and minor design changes, we recommend cross-referencing your original part number against your engine’s service manual. If you have an alternative part number (e.g., ME200281), please contact our technical team for verification before ordering.

Q2: What are the symptoms of a worn thrust washer in a 4M40 engine?

A: Common signs include excessive crankshaft end play (audible knocking or clunking when the clutch is engaged/disengaged), oil pressure fluctuations, and premature wear of main bearings. If you measure more than 0.30mm (0.012 inches) of axial play, replacement is recommended immediately to prevent catastrophic engine damage.

Q3: Can this thrust washer be installed during a routine engine overhaul?

A: Yes, this is a standard replacement part during major engine overhauls. It should be installed with new main bearings and properly torqued to manufacturer specifications. Ensure the crankshaft thrust surfaces are clean and undamaged before installation. We recommend professional installation by a qualified diesel mechanic.
