FAQ

Q1: How do I confirm this thrust washer fits my Mitsubishi 4G64 engine?
A: Verify your existing part number matches MD351820. Remove the old thrust washer and measure its inner diameter, outer diameter, and thickness. Compare these measurements to the OEM specifications for the 4G64 engine. If you’re unsure, contact our technical team with your engine serial number and equipment model for cross-reference assistance.

Q2: What are the signs of a worn thrust washer in a 4G64 engine?
A: Common symptoms include excessive crankshaft end-play (audible knocking during acceleration/deceleration), reduced oil pressure, metallic debris in engine oil, and vibration at idle. If you detect any of these issues, inspect the thrust washer immediately to prevent catastrophic engine damage. Replace the washer if thickness has decreased by more than 0.1mm from OEM specifications.

Q3: Can I install this thrust washer without special tools?
A: Basic mechanical skills and standard engine tools are sufficient for replacement. However, we recommend professional installation by a qualified diesel mechanic. Critical steps include: (1) properly supporting the crankshaft during removal, (2) cleaning the thrust washer housing thoroughly, (3) applying clean engine oil to the new washer before installation, and (4) verifying correct end-play (typically 0.05-0.15mm for 4G64 engines) after installation. Always refer to the Mitsubishi service manual for your specific engine variant.
