3327713 XCMG GR2605 motor grader spring
3327713 is a special return spring for clutches, gearboxes and hydraulic control mechanisms of construction machinery. Made of high-quality spring steel with precise coiling and heat treatment, it features stable elastic force, good fatigue resistance and impact resistance. It is mainly used for clutch piston return, valve reset, gear locking and pressure compensation, ensuring reliable performance under frequent reciprocating conditions.
Technical Parameters
- Model: 3327713
- Type: Cylindrical helical compression spring
- Material: High-quality spring steel (65Mn or 55CrSi)
- Surface Treatment: Blackening / electrophoretic anti-rust treatment
- Heat Treatment: Quenching + medium temperature tempering for stable elasticity
- Load Characteristic: Constant stiffness design with even return force
- Operating Temperature: -40℃～120℃
- Structure: Equal-pitch spiral structure with flat ends and even stress
Application Scenarios
Suitable for gearbox clutch assemblies, shift pistons, hydraulic control valves, brake mechanisms and other parts of construction machinery such as loaders, graders, rollers and forklifts. Mainly used for piston return, friction plate set separation reset, pressure buffer and locking mechanism reset, suitable for frequent operation, high pressure and vibration conditions.
Common Faults & Troubleshooting
- Elastic attenuation and slow return: Caused by long-term fatigue or overheating. Replace 3327713 spring.
- Fracture failure: Resulted from impact overload or material fatigue. Replace with new spring and check for jamming in assembly space.
- Deformation and skew: Caused by eccentric installation or lateral force. Reinstall positioning and replace spring.
- Rust and seizure: Caused by damp and oily environment. Replace directly if elasticity is abnormal after cleaning.
