133-7029 42 mm Head Diameter Exhaust Valve Stem
Cat® 42 mm Head Diameter Exhaust Valve Stem for Cylinder Head
Description
The exhaust valve stem is an important component of an internal combustion engine. The valve stem is typically made of high-strength material that can withstand the high temperatures and pressures generated by the engine. It is designed to fit tightly in the valve guide, a cylindrical sleeve pressed into the cylinder head.
Features
- Includes two retainer grooves to hold the valve retainer in place
- Withstands wear between the valve stem and the guide
- Features a 45.75° valve seat face, which reduces carbon buildup on the valve and seat and helps improve engine performance
Applications
The exhaust valve stem controls the flow of exhaust gas leaving the engine combustion chamber during the exhaust stroke of the engine cycle.
