3501723 XCMG GR2605 motor grader piston
3501723 piston is a core pressure-bearing component in hydraulic clutches and transmission shift mechanisms of construction machinery. It is driven by hydraulic oil to push the friction plate set for clutch and shift operations. Made of precision forged steel or aluminum alloy with high surface finish and excellent pressure resistance, it features sensitive action and reliable sealing under frequent reversing and high-pressure impact conditions, ensuring quick response of the transmission system.
Technical Parameters
- Model: 3501723
- Type: Clutch hydraulic piston
- Material: High-strength forged steel / lightweight aluminum alloy
- Surface Treatment: Precision grinding and polishing, anti-rust and wear-resistant treatment
- Fit Accuracy: High dimensional accuracy with uniform clearance with cylinder bore
- Seal Structure: With seal ring grooves for O-ring or combined seal
- Working Pressure: Suitable for standard hydraulic pressure of construction machinery transmissions
- Operating Temperature: -40℃～120℃
- Structure: Disc-type integral structure with flat end face and even stress
Application Scenarios
Suitable for transmission shift clutches, steering clutches, hydraulic brake cylinders and other parts of construction machinery such as loaders, graders, rollers and forklifts. Installed inside the clutch cylinder to compress or release the friction plate set, realizing power engagement, disconnection and gear shifting, adapting to frequent operation, vibration and heavy-duty conditions.
Common Faults & Troubleshooting
- Pressure loss and slipping: Caused by damaged seals or piston surface scratches. Replace 3501723 piston and seal kit.
- Seizure and no return: Resulted from oil impurities, rust or deformation. Clean cylinder and replace piston.
- Slow engagement: Caused by excessive wear clearance. Replace with new piston to restore oil pressure response.
- Oil leakage: Due to damaged seal grooves or uneven end face. Replace piston and check cylinder bore accuracy.
