3349903 XCMG GR2605 motor grader adjustment shim 0.15

The 3349903 adjusting shim is an ultra-thin adjusting shim used in the precision assembly of construction machinery. With a nominal thickness of 0.15mm, it is mainly used for mechanism clearance compensation, fine-tuning of assembly precision, and leveling of stress surfaces. It is widely used in gearboxes, hinged parts, bearing housings, and other precision-fitting positions to ensure reasonable operating clearances and smooth operation.

Technical Parameters

Model: 3349903
Thickness: 0.15mm
Material: High carbon steel / Stainless steel
Hardness: High hardness, wear-resistant, not easily crushed or deformed
Applicable Temperature: -40℃～120℃
Precision: Small thickness tolerance, suitable for precision clearance adjustment

Suitable Scenarios

Suitable for drive axles, gearboxes, balance boxes, hinge pins, bearing housings, and other parts requiring precision clearance control in construction machinery such as loaders, graders, and road rollers; used to eliminate assembly clearances, correct coaxiality, compensate for wear, and ensure smooth, jam-free operation of the mechanism.

Common Faults and Troubleshooting

Excessive clearance, abnormal operating noise: Often caused by missing, worn, or mismatched thickness adjusting shims. Replace with 0.15mm adjusting shims and reassemble.

Shim crushing/deformation: Caused by overload or uneven assembly stress. Replace with new adjusting shims and check the flatness of the mounting surface.

Shim displacement/falling off: Caused by improper positioning or insufficient tightening during installation. Clean the mounting surface, correctly place the shims, and tighten.

Matching surface jamming: Caused by too many shims or incorrect thickness. Use 0.15mm single shims or combinations for adjustment according to the original manufacturer’s standards.
