Application Information
The CAT 282-7944 Valve Lifter is an integral component of Caterpillar’s electronically controlled unit injector system. As the camshaft rotates, the lifter follows the cam profile and actuates the unit injector, ensuring precise fuel injection timing and consistent engine performance. Accurate injector operation is essential for maintaining combustion efficiency, engine power, fuel economy, and emissions performance.
Manufactured to Caterpillar OEM standards, the valve lifter is designed to withstand:
- Continuous camshaft contact
- High engine operating temperatures
- Constant lubrication exposure
- Heavy injector actuation loads
- Severe mining, marine, industrial, and petroleum operating environments
These characteristics help maintain reliable engine performance and long service life.
