71915 XCMG GR2605 motor grader pin
71915 pin is a general positioning and fastening pin for construction machinery. It is mainly used for positioning, anti-rotation and axial limit of shafts, gears, bearings and housing components, bearing shear and compression loads. It features simple structure and high fitting accuracy, maintaining reliable positioning under vibration conditions, widely used in drive axles, gearboxes, wheel reducers and other parts.
Technical Parameters
- Model: 71915
- Type: Location Pin / Cylindrical Pin
- Material: High-quality alloy steel with heat treatment strengthening
- Surface Treatment: Blackening for rust prevention
- Hardness: High shear strength, wear-resistant and not easy to deform
- Operating Temperature: -40℃～120℃
- Structure: Solid cylindrical structure with smooth surface and stable assembly clearance
Application Scenarios
Suitable for drive axles, gearboxes, planetary mechanisms, bearing seats, end covers and support components of construction machinery such as loaders, graders, rollers and forklifts. Used for precise positioning, anti-rotation and axial fixing, suitable for heavy-duty, vibration and continuous working conditions.
Common Faults & Troubleshooting
- Wear looseness and positioning failure: Increased fitting clearance caused by long-term load. Replace 71915 pin and inspect mounting holes.
- Bending deformation: Caused by impact load or eccentric installation. Replace with a new pin and adjust assembly position.
- Breakage or loss: Caused by vibration fatigue or locking structure failure. Replace with a new pin and check locking parts such as retaining rings and circlips.
- Rust and seizure: Caused by damp and oily environment. Replace directly if unusable after cleaning.
