449-7113 Exhaust Valve Rotator
Cat® Exhaust Valve Rotator is used to distribute heat load across the valve face
Description
The exhaust valve rotator is a spring-loaded device installed on top of the exhaust valve. Each time the valve opens and closes, the rotator turns the valve slightly. It helps distribute the heat load evenly across the surface of the valve, which helps prevent it from warping or burning.
Attributes
- Improves engine performance by reducing heat
- Rotates when loaded from 785 N starting load to 1763 N at 900 IPM
- Prevents premature valve failure
- More durable, with longer service life
Applications
This exhaust valve rotator helps hold the spring in place and rotates the exhaust valve in the cylinder head, distributing heat transfer evenly across the valve face.
