3477083 XCMG GR2605 motor grader pin
3477083 is a high-strength pin / locating pin for construction machinery braking systems, shift mechanisms and articulated joints. Precision forged from alloy steel with quenching and tempering treatment, it features high shear strength and wear resistance. It is mainly used for articulation limit, clearance control and torque transmission, maintaining dimensional stability under heavy load and frequent swinging.
Technical Parameters
- Model: 3477083
- Type: Cylindrical pin / locating pin
- Material: 40Cr / 42CrMo high-strength alloy steel
- Heat treatment: Quenching and tempering + surface hardening
- Surface hardness: HRC 45–55
- Tolerance: h6 / h7 precision fit
- Surface treatment: Blackening / phosphating for rust prevention
- Operating temperature: -40℃～120℃
- Load performance: Shear resistant, extrusion resistant, fatigue resistant
- Lubrication: Grease lubrication, oil hole optional
Application Scenarios
Suitable for heavy construction machinery such as loaders, graders, rollers and forklifts. Mainly used in brake calipers, shift links, fork mechanisms, rocker supports and clutch linkages. It provides articulation positioning, clearance control and force transmission, adapting to harsh working conditions with heavy impact, frequent movement, dust and muddy water.
Common Faults & Troubleshooting
- Wear and looseness: Surface wear and increased clearance caused by long-term movement. Replace 3477083 pin and check mating bushings.
- Bending deformation: Caused by overload impact or misalignment. Replace with new pin and correct component position before assembly.
- Rust and seizure: Due to water intrusion and poor lubrication. Replace pin, clean bore and apply grease.
- Shear fracture: Caused by excessive impact or fatigue. Replace high-strength 3477083 pin and check mechanism for abnormal loading.
