3327663 XCMG GR2605 motor grader feedback disc
3327663 is a key signal feedback component in transmission and hydraulic shift control systems of construction machinery. It is mainly used to sense clutch engagement status, gear position or oil pressure feedback, converting mechanical displacement signals into hydraulic or mechanical feedback signals to achieve smooth shifting, pressure adjustment and precise clutch control. Made with precision stamping and heat treatment, it features high rigidity and fast response, working stably under frequent shifting and vibration conditions.
Technical Parameters
- Model: 3327663
- Type: Shift feedback disc / Pressure feedback disc
- Material: High-quality alloy structural steel
- Surface Treatment: Blackening anti-rust treatment, flat end face
- Precision: High position feedback accuracy, sensitive response without delay
- Operating Temperature: -40℃～120℃
- Structure: Disc type with positioning grooves / bosses, linked with control valve or piston
- Features: Deformation resistant, impact resistant, stable linear feedback
Application Scenarios
Suitable for power shift transmissions, hydraulic control valve assemblies and clutch servo mechanisms of construction machinery such as loaders, graders, rollers and forklifts. Installed on the shift piston or control valve end to real-time feedback clutch engagement stroke and oil pressure status, improving shifting smoothness and preventing shock and slippage.
Common Faults & Troubleshooting
- Shift shock and hesitation: Caused by feedback disc deformation or wear leading to inaccurate signal. Replace 3327663 feedback disc.
- Slow gear engagement: Due to feedback disc seizure or boss wear causing control failure. Clean and replace feedback disc.
- Abnormal noise and looseness: Caused by worn or broken mounting parts. Replace with new part and check installation clearance.
- Feedback failure: Resulted from surface fatigue damage or positioning failure. Replace directly to restore shift control accuracy.
