3454813 XCMG GR2605 motor grader support

The 3454813 support is a specialized structural support component for construction machinery. It is primarily used for mechanism support, positioning, load bearing, and clearance maintenance, providing stable support for transmission, articulation, and travel systems. It ensures component coaxiality and smooth operation, and belongs to the category of load-bearing basic components.

Technical Parameters

Model: 3454813
Material: Alloy steel / High-quality structural steel
Surface Treatment: Quenching + Blackening / Rust prevention treatment
Hardness: High wear resistance, extrusion resistance, and not easily deformed
Applicable Temperature: -40℃～120℃
Precision: High dimensional accuracy, suitable for precision assembly and positioning

Suitable Scenarios

Suitable for balance boxes, drive axles, gearboxes, articulation mechanisms, wheel assemblies, etc., in construction machinery such as loaders, graders, and road rollers; used for supporting and positioning shaft and gear components, distributing loads, reducing uneven wear, and ensuring concentric operation and uniform force distribution.

Common Faults and Troubleshooting

**Bearer Wear/Uneven Wear:** Caused by uneven stress over a long period or insufficient lubrication. Replace bearing 3454813 and check coaxiality.

**Deformation/Loosening:** Caused by overload impact or improper tightening. Replace bearing and tighten to standard torque.

**Abnormal Noise/Stuck:** Caused by abnormal bearing clearance or surface scratches. Repair the mating surfaces and reassemble.

**Positioning Failure:** Caused by bearing dimensional wear exceeding tolerances. Replace with a bearing of original factory specifications to restore accuracy.
