FAQ
Q: How do I know if this seal fits my engine? A: Check the part number stamped on your existing crankshaft oil seal. If it matches 8-98334339-0, 8-98334482-0, 8983343390, or 8983344820, this seal is a direct fit for your Isuzu 4HK1, 6HK1, or 6HH1 engine. You can also cross-reference your engine model and serial number with our compatibility list.
Q: What is the recommended installation procedure? A: Ensure the crankshaft surface is clean and free of burrs. Lubricate the seal lip with clean engine oil before installation. Use a proper seal driver tool to press the seal evenly into the housing until it seats flush. Avoid hitting the seal directly with a hammer, as this can damage the sealing lip.
Q: How long does this seal typically last? A: As a genuine Isuzu part, this crankshaft oil seal is designed to last as long as the original factory component—often exceeding 100,000 miles or several thousand operating hours under normal conditions. Proper installation and maintaining proper engine oil levels will maximize its service life. If you notice leaks, inspect the seal and crankshaft surface for wear.
