FAQ

Q: How do I confirm this thrust washer fits my Komatsu 6D140 engine?
A: Verify your engine serial number and original part number. The 6210-21-8050 is standard for 6D140 engines in PC200 excavators and FD series forklifts. Measure the crankshaft journal width (90mm ID) to ensure compatibility. If unsure, contact us with your equipment model and year.

Q: What is the installation procedure for this thrust washer?
A: During engine reassembly, apply clean engine oil to the thrust washer surface. Install it with the oil grooves facing the crankshaft. Ensure the thrust washer is seated properly in the engine block recess. Check crankshaft end-play using a dial indicator (spec: 0.10–0.30 mm). Torque main bearing caps to factory specifications.

Q: How does this compare to aftermarket alternatives?
A: Our thrust washer is manufactured to OEM tolerances using superior materials (copper-lead alloy) for better heat dissipation and wear resistance compared to generic aftermarket parts. It is a direct drop-in replacement, reducing the risk of premature failure due to incorrect clearances.
