285-4074 Crankshaft Seal

Description

The crankshaft seal assembly is used to retain engine oil and prevent external contaminants from entering the engine oil system.

Seal assemblies for dry applications (air-to-oil interface) typically include a primary sealing lip that prevents engine oil leakage, a dust lip and a wear sleeve. 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.

Features

Cat® crankshaft seal assemblies are precisely engineered to the requirements of the most demanding applications. They must withstand high speeds, high temperatures and frequent axial movement.

The crankshaft seal assembly includes a wear sleeve that protects the crankshaft from wear and provides an optimal contact surface for the lip seal. The wear sleeve also avoids costly crankshaft repair or replacement, making service easier, faster, and more economical.

Cat® sealing systems protect more expensive parts from leakage and contamination. Genuine Cat® seals protect your investment.

Applications

The crankshaft seal assembly is used on engine crankshafts and in other high-speed rotating applications, such as some water pumps.

Note: The entire crankshaft seal assembly should be replaced as a whole and should not be serviced individually.
