FAQ

Q: Is this thrust washer a direct fit for my Cummins QSX15 engine?

A: Yes, this part (3691445) is manufactured to the exact OEM size for the QSX15 engine. However, we recommend verifying the part number on your old thrust washer or consulting your engine’s service manual to ensure it matches your specific engine configuration (e.g., model year or build specification).

Q: What is the installation process for this thrust washer?

A: Installation requires removing the oil pan and main bearing caps to access the thrust washer. It is a precision-fit part and should be installed with clean hands and a small amount of engine oil to prevent initial scuffing. We recommend replacing all thrust washers (upper and lower halves) simultaneously and checking crankshaft end-play after installation using a dial indicator.

Q: How can I ensure the longevity of this part after installation?

A: Longevity depends on proper lubrication and engine maintenance. Ensure your engine’s oil pressure is within spec and change oil and filters at recommended intervals. Avoid prolonged engine operation at high loads without sufficient warm-up, as this can stress the thrust bearing system. Regular inspection of the oil pressure gauge is also advisable.
