3477073 XCMG GR2605 motor grader spring

Technical Parameters

• Model: 3477073
• Type: Cylindrical helical compression spring
• Material: 60Si2Mn / 55CrSi alloy spring steel
• Heat treatment: Quenching + medium temperature tempering, spring strengthening process
• Surface hardness: HRC 42–48
• Load feature: Constant stiffness linear compression spring
• Working stroke: Matches standard brake / control mechanism stroke
• Operating temperature: -40℃～120℃
• Surface treatment: Blackening / electrophoretic rust prevention
• Features: High fatigue life, stable elastic force, no permanent deformation, oil and corrosion resistant

Application Scenarios

• Brake caliper piston return, brake shoe return mechanism
• Transmission shift fork, control valve core return
• Clutch release mechanism, hydraulic valve group pressure compensation

  Adapts to frequent action, vibration impact and oil immersion working conditions to ensure timely component return and stable clearance.

Common Faults & Troubleshooting

• Elastic attenuation: Elasticity decreases due to long-term fatigue, slow brake return. Replace 3477073 spring.
• Fracture failure: Caused by high-frequency reciprocating or overload impact. Replace with new spring and check mechanism for sticking.
• Rust and seizure: Spring jams due to mud and impurities. Clean and replace spring, improve sealing protection.
• Deformation & skew: Caused by eccentric installation or lateral force. Reinstall alignedly and replace with new spring.
