Rear Crankshaft Oil Seal 8-97049146-0 8970491460 for ISUZU NKR NPR TFR TFS 4JB1 4JG2 4JA1 — Verified OEM Fit 95×118×10 mm NBR/FKM Rear Main Seal
This rear crankshaft oil seal with OEM numbers 8-97049146-0 and 8970491460 is a verified direct-fit replacement for ISUZU NKR/NPR/TFR/TFS/ELF light trucks and pickups, as well as Holden Rodeo/Colorado, Opel Campo/Monterey, and Vauxhall Brava/Monterey models equipped with 4JB1/4JG2/4JA1/4JX1/4ZA1/4FC1/4FG1 diesel engines.
The rear crankshaft oil seal creates a dynamic seal between the rotating crankshaft and stationary engine block/flywheel housing. It retains engine oil within the crankcase while preventing external contaminants from entering the clutch or flywheel area.
The dual-lip design features a primary sealing lip that maintains contact with the crankshaft surface under spring tension, and a secondary dust lip that blocks water, mud, and debris. The NBR (Nitrile Butadiene Rubber) or FKM (Fluoroelastomer) construction provides excellent resistance to engine oil, high temperatures, and compression set.
Replace the rear crankshaft oil seal when any of these symptoms appear:
- Engine oil leakage between engine and transmission — visible oil traces at bell housing or dripping from transmission area
- Oil contamination on clutch disc or flywheel — causing slipping or chatter
- Oil accumulation at bottom of bell housing — indicates seal lip failure
- Low engine oil level without visible external leaks elsewhere — gradual oil loss
- Visible cracks, swelling, or hardening of rubber — indicates aging and loss of elastic properties
