FAQ
Q1: How do I confirm this seal fits my Isuzu 4HG1 engine? A: First, locate the original part number on your old seal. Common locations include the rubber lip or metal casing. If the number is 8-97602379-0 or BZ4365E, this seal is a direct match. Alternatively, measure the inner diameter (crankshaft size), outer diameter (housing bore), and width of your old seal and compare it to the OEM specifications for the 4HG1 engine.
Q2: What is the correct installation procedure for a crankshaft rear oil seal? A: Installation requires precision. Clean the housing bore and crankshaft surface thoroughly. Lubricate the seal lip with clean engine oil. Use a proper seal driver tool to press the seal evenly into the housing until it is flush. Never hammer directly on the seal, as this can distort the metal casing. Ensure the seal is oriented correctly (spring side facing the engine interior).
Q3: Can this seal be used on a 4HE1 engine if the original part number is different? A: Possibly. The 4HG1 and 4HE1 engines share many internal components, including often the same crankshaft rear seal dimensions. However, we strongly recommend verifying the part number on your existing seal (e.g., 8-97602379-0) or measuring the seal dimensions before purchase. If your original number differs, please contact us with your engine model and serial number for confirmation.
