Valve Tappet Adjusting Screw
Item Name Code (INC) 33266
![]() |
An externally threaded screw-like device with a hexagon, square, slotted or any other type drive end. The other end may have a spherical ball, socket or other type of machined surface. It may have a concentric hole along the longitudinal centerline and a hole perpendicular to the axis joining the concentric hole for lubrication. It is specifically designed to be used as a means for adjusting engine poppet valve tappet clearances and may be furnished with a lock nut.
Additional Information for Valve Tappet Adjusting Screw
Valve tappet adjusting screws, also known as valve lash adjusters or valve clearance adjusters, are components used in internal combustion engines to adjust the clearance between the valve stem and the rocker arm or camshaft.
The valve tappet adjusting screw is typically located on top of the valve lifter or tappet, which is responsible for transmitting the motion from the camshaft to the valve. By adjusting the position of the adjusting screw, the clearance between the valve stem and the rocker arm or camshaft can be increased or decreased.
Proper valve clearance is important for the efficient operation of the engine. If the clearance is too small, the valve may not fully close, leading to poor engine performance and potential damage. On the other hand, if the clearance is too large, it can cause excessive noise, reduced power, and increased wear on the valve train components.
Valve tappet adjusting screws are typically adjusted during routine maintenance or when there are symptoms of valve clearance issues. The adjustment process involves measuring the clearance using a feeler gauge and then turning the adjusting screw to achieve the desired clearance.
It's important to consult the specific manufacturer's guidelines or a service manual for your engine to ensure proper adjustment procedures and specifications for your particular vehicle.
