SHIM (CAT CT0389899)

CT0389899: A worn shim can allow excessive clearance between mating components, leading to accelerated wear or noise. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference part number CT0389899. The shim functions as a thin spacer used to adjust the gap or alignment between two parts in a mechanical assembly. Its plain mechanical role is to fill a precise gap to maintain proper positioning under load. If the shim degrades or is omitted, the resulting looseness may cause vibration or uneven contact over time. The item ships at approximately 0.351 POUNDS.
