Product Descreiption
1. Basic Parameters
- Part Number: 3965966-QSL
- Product Type: Engine valve tappet (hydraulic tappet / solid tappet, standard engine valvetrain component)
- Material: High-strength alloy steel, surface hardened for wear resistance
- Dimension: Standard OEM matching size, precision machined to fit designated engine models
- Design Feature: High precision tolerance, anti-wear, low noise, heat-resistant
2. Installation Position
This tappet is installed inside the engine cylinder head, located between the engine camshaft and the engine valve stem. It sits in the tappet bore of the cylinder head, directly contacting the camshaft lobe on one side and the valve assembly on the other.
3. Main Function
- Transmit the lifting force from the camshaft to open and close the intake and exhaust valves synchronously.
- Maintain proper valve lash (valve clearance), eliminate valve impact and operating noise.
- Buffer mechanical vibration and friction during engine operation, protect camshaft and valves from premature wear.
- Ensure stable and consistent operation of the engine valvetrain to guarantee normal engine power output.
