FAQ

Q: How can I confirm this oil seal fits my engine?
A: Please check the model number on your engine’s nameplate. This seal is specifically for Hino J05E and J08E engines. Also, compare your existing part number to SZ311-79002. If you are unsure, contact us with your engine serial number for verification.

Q: What should I check during installation?
A: Ensure the crankshaft surface is clean and free of burrs or grooves. Lubricate the seal lip with clean engine oil before installation. Use the correct seal driver tool to press the seal in squarely to the correct depth to avoid damage. Incorrect installation is the most common cause of premature seal failure.

Q: What causes a crankshaft oil seal to fail?
A: Common causes include normal wear over time, a clogged positive crankcase ventilation (PCV) system causing excessive crankcase pressure, a worn crankshaft bearing allowing excessive shaft movement, or damage during installation. Replacing the seal as part of regular engine maintenance helps prevent unexpected oil leaks.
