The Rear Crankshaft Oil Seal (OEM Numbers: 8-97602379-0 / 8976023790) is a premium-quality, direct replacement sealing component designed for Isuzu FVZ34 heavy-duty trucks equipped with the 6HK1 diesel engine.

Function: Rear crankshaft oil seal (rear main seal) prevents engine oil from leaking out of the rear main bearing area, between the crankshaft and the engine block. Ensures oil retention and protects the flywheel/clutch from contamination.

• OE Quality: Manufactured to Isuzu dimensional and material specifications for perfect leak-proof fit
• High-Temperature Resistant: Elastomer lip withstands engine heat and oil exposure without hardening or cracking
• Garter Spring: Integrated spring maintains constant lip pressure on the rotating crankshaft
• Corrosion-Protected Metal Case: Prevents rust and ensures secure press-fit into the engine housing
• Restores Oil Containment: Eliminates rear main oil leaks that can damage the clutch
• Direct Replacement: Easy installation with proper tools
• Cost-Effective: Affordable alternative to genuine dealer seals without compromising reliability

This rear crankshaft oil seal is specifically designed for Isuzu FVZ34 trucks with 6HK1 engine.

• ISUZU FVZ34 (heavy-duty truck, 6HK1 engine)
• May also fit other Isuzu models using the 6HK1 engine (e.g., FVR, CXZ) - verify compatibility

• 6-Cylinder, Inline Diesel, Common Rail
• Displacement: 7.8L (7790cc)

Installation steps (typical for rear main seal):

1. Remove the transmission, flywheel, and clutch (if equipped)
2. Clean the rear of the engine block and the crankshaft flange
3. Remove the old seal using a seal puller, being careful not to scratch surfaces
4. Inspect the crankshaft sealing surface for grooves or damage
5. Lightly lubricate the new seal's lip with clean engine oil
6. Position the new seal squarely into the housing bore
7. Using a seal installer, press the seal evenly until properly seated
8. Reinstall the flywheel, clutch, and transmission
9. Refill engine oil if drained
10. Start engine and check for leaks
