FAQ

Q1: How do I confirm this thrust washer fits my 6HK1 engine?
A: Verify the part number on your old washer. The numbers 8-97386549-0 or 8-97386548-0 are the direct OEM references for the 6HK1 and 4HK1 series. If your engine serial number falls within the typical range for these models, this part is the correct replacement. Always cross-check with your engine’s parts manual if you are uncertain.

Q2: What is the installation procedure for a thrust washer?
A: Installation requires removing the oil pan and main bearing caps. The old thrust washer is typically located on the center main bearing (or as per your engine manual). Clean the bearing saddle, lubricate the new washer with clean engine oil, and install it with the oil grooves facing the crankshaft thrust face. Torque all main bearing cap bolts to the manufacturer’s specifications using a calibrated torque wrench. We recommend professional installation by a certified diesel mechanic.

Q3: Can a worn thrust washer cause engine damage if not replaced?
A: Yes. A worn or failed thrust washer allows excessive crankshaft end-play. This can lead to severe damage including: clutch disengagement issues, connecting rod misalignment, increased bearing wear, and potential crankshaft or block damage. If you notice a knocking sound during clutch engagement or excessive axial movement of the crankshaft pulley, immediate inspection and replacement are advised.
