Application Information
The CAT 574-4543 Engine Valve Lifter is a critical component of the engine valve mechanism. Positioned between the camshaft and the rocker arm, it follows the camshaft profile and transfers motion to actuate the engine valves. The roller-style design helps reduce friction and wear while maintaining precise valve timing and proper valve clearance, contributing to efficient combustion, reliable engine performance, and long service life.
Manufactured to Caterpillar OEM standards, the valve lifter is designed to withstand:
- Continuous camshaft contact
- High valve train loads
- Constant lubrication exposure
- High engine operating temperatures
- Severe mining, construction, marine, petroleum, and power generation environments
