Product Description
The genuine OEM Toyota 90311-58007 crankshaft oil seal (SEAL, TYPE T OI) is a premium-quality radial shaft seal that plays a crucial role in hermetically sealing the engine lubrication system. This specially engineered seal prevents engine oil leaks at the rotating ends of the crankshaft while providing effective protection against the ingress of external contaminants, dust, and moisture.
Technical Features and Characteristics:- Type: Type T OI – oil seal featuring a specialized running surface design and optimized sealing lip geometry.
- Material Composition: High heat- and chemical-resistant elastomer (typically fluoroelastomer / FKM or polyacrylate / ACM) that reliably withstands engine oil, additives, and high operating temperatures.
- Design: Equipped with an integrated auxiliary dust lip and a garter-spring-tensioned sealing lip for a precise fit and minimal shaft wear.
The crankshaft oil seal is in direct contact with the high-speed rotating crankshaft. Its function is to maintain oil retention inside the engine block. The precise manufacturing tolerances of genuine Toyota parts ensure an optimal seal with minimal frictional resistance, reducing shaft wear and maximizing engine efficiency.
Typical Symptoms of Wear and Failure:- Oil leaks or oil mist appearing on the lower engine block or around the crankshaft pulley.
- Continuous drop in engine oil level.
- Clutch slippage (in case of a rear crankshaft seal leak if oil reaches the clutch disc).
- Physical hardening, cracking, or loss of elasticity of the sealing material due to aging and thermal stress.
When replacing the oil seal, using genuine OEM-quality parts, thoroughly cleaning the mating surfaces, and utilizing suitable specialized tools are always recommended to achieve maximum service life and dependable operation.
