A Front Idler Shim is a thin, flat piece of metal that is placed between the front idler wheel and the track roller frame of a tracked machine. It is used to adjust the clearance between the two parts, which is necessary to ensure that the track roller frame rotates smoothly and without excessive wear.

Attributes:
• Withstand the harsh operating conditions
• Reduce noise and vibration from the track roller

Applications:
A Front Idler Shim is used to protect the track roller frame from damage by providing a barrier between the front idler wheel and the frame.
