317-6539 127.13 mm OD Engine Lip Seal
Cat® engine lip seal prevents fluid leakage and maintains proper lubrication between the crankshaft gear and the engine block.
Description
The crankshaft seal is used to retain engine oil and prevent external contaminants from entering the engine oil system.
Seals for dry applications (air-to-oil interface) typically include a primary sealing lip that prevents engine oil leakage and a dust lip. In wet applications (oil-to-oil interface), the dust lip is replaced with an auxiliary lip that can pump external fluid away from the engine. Some seals have a plastic sleeve to assist with the installation process.
Features
Cat® crankshaft seals are precisely engineered for the most demanding applications and withstand high speeds, high temperatures and frequent axial movement.
Cat® sealing systems go through a robust design, testing and validation process. Protect your investment with the latest Genuine Cat® seals.
Applications
The crankshaft seal is used on engine crankshafts and in other high-speed rotating applications, such as some water pumps.
