5298564 | Cummins ISX .020 Inch Thickness Liner Shim, New DOHC / SOHC

A diesel engine shim is a thin piece of metal that is inserted between the engine block and the cylinder head to adjust the clearance between the valve train components. The function of a shim is to ensure that the valves open and close at the correct time and with the correct amount of lift.

 

Shims should be replaced when the clearance between the valve train components becomes too large or too small. If the clearance is too large, the engine may experience a loss of power and increased emissions. If the clearance is too small, the engine may experience valve damage or a loss of compression. It is important to follow the manufacturer's recommended maintenance schedule and replace shims as needed to ensure proper engine performance and longevity.
