Stop oil leaks at the source and safeguard your engine’s driveline with this Genuine Toyota OEM Rear Main Crankshaft Oil Seal (Part # 90311-92010). Engineered to exact factory tolerances, this original equipment seal maintains a secure, long-lasting barrier around the rear crankshaft journal—preventing low oil levels, bellhousing contamination, and clutch slip during transmission or rear-main service.
Whether you are performing a clutch/flywheel replacement, completing a major engine overhaul, or performing preventative maintenance on 1GR-FE, 2GR-FE, 3MZ-FE, 5VZ-FE, or 2AZ-FE engines, fitting a genuine OEM seal ensures factory-grade fitment and peace of mind.
Factory Genuine Quality: Designed specifically by Toyota for maximum thermal resistance, precise elastomeric lip pressure, and optimal dust-exclusion performance.
Leak & Contamination Protection: Prevents persistent oil seepage into the clutch or bellhousing area, preserving clutch disc integrity and maintaining proper engine lubrication.
Exact OEM Dimensions: Direct drop-in replacement measuring 92mm (ID) x 110mm (OD) x 8.5mm (Width) for seamless installation into the rear oil seal retainer housing.
