FAQ

Q: How do I confirm if this oil seal (90311-99002) fits my Hino engine?
A: The primary identifier is your engine model. This seal is specifically for the Hino W06D engine. Please locate your engine model plate on the engine block. If your engine is a W06D, this part is the correct rear crankshaft seal. For absolute certainty, you can compare the old seal’s dimensions (inner diameter, outer diameter, and thickness) with the OEM part number 90311-99002.

Q: What are the signs of a failing crankshaft rear oil seal?
A: Common symptoms include visible oil leaking from the bottom rear of the engine (between the engine and transmission), a burning oil smell (from oil dripping onto hot exhaust components), and low engine oil levels. If you notice these signs, the seal should be replaced promptly to prevent damage to the clutch and transmission.

Q: Is installation of this seal difficult?
A: Replacing a crankshaft rear oil seal is a complex job that typically requires removing the transmission and flywheel. It is recommended to be performed by a qualified diesel mechanic. Proper installation is critical to avoid damaging the new seal. We advise lubricating the seal lip with engine oil before installation and using the correct seal driver tool to seat it evenly.
