4. Setup and Installation
This hydraulic cylinder is a replacement part. Installation should be performed by a qualified individual familiar with motorcycle lift mechanics.
- Preparation: Ensure the motorcycle lift is fully lowered and disconnected from any power source. Secure the lift to prevent accidental movement.
- Removal of Old Cylinder: Carefully disconnect the old hydraulic cylinder from the lift frame. Be aware of any hydraulic fluid that may leak. Dispose of old fluid and parts responsibly.
- Mounting the New Cylinder: Position the WilTec Hydraulic Cylinder (Model 50799-04) into the designated mounting points on the motorcycle lift. Ensure all bolts and fasteners are correctly aligned and securely tightened according to the lift manufacturer's specifications.
- Connecting Linkages: Reattach any linkages or levers that connect to the cylinder's pumping mechanism.
- Initial Test: Before placing a load on the lift, perform several full lift and lower cycles to ensure smooth operation and proper seating of the cylinder. Check for any leaks or unusual noises.

5. Operating Instructions
Once installed, the hydraulic cylinder operates as part of your motorcycle lift system. Refer to your motorcycle lift's specific user manual for detailed operating procedures. Generally, the operation involves:
- Lifting: Actuate the foot pedal or lever on your motorcycle lift to pump hydraulic fluid, extending the cylinder and raising the lift platform.
- Holding: The cylinder is designed to hold the load at the desired height. Always engage safety locks on your motorcycle lift once the desired height is reached.
- Lowering: Release the pressure valve on your motorcycle lift to slowly retract the cylinder, lowering the lift platform. Control the descent speed carefully.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your hydraulic cylinder.
- Inspection: Periodically inspect the cylinder for any signs of leaks, corrosion, or physical damage. Check the integrity of all connections and mounting points.
- Cleaning: Keep the cylinder clean and free from dirt, dust, and debris. Use a clean cloth to wipe down the exterior.
- Lubrication: Apply a thin layer of appropriate hydraulic oil to the exposed piston rod to prevent rust and ensure smooth operation. Consult your motorcycle lift manual for specific lubrication requirements.
- Hydraulic Fluid: If the cylinder requires refilling or fluid replacement (typically part of the overall lift system maintenance), use only hydraulic fluid specified by the lift manufacturer.
- Storage: When not in use for extended periods, store the cylinder in a dry, clean environment, preferably in a fully retracted position.
7. Troubleshooting
If you encounter issues with your hydraulic cylinder, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cylinder does not lift or lifts slowly. | Low hydraulic fluid level, air in the system, or internal seal damage. | Check hydraulic fluid level and refill if necessary. Bleed air from the system (refer to lift manual). If seals are damaged, professional repair or replacement is required. |
| Cylinder leaks hydraulic fluid. | Damaged seals or loose connections. | Inspect for visible leaks. Tighten connections. If seals are damaged, the cylinder requires professional repair or replacement. |
| Cylinder lowers unexpectedly. | Faulty release valve or internal bypass. | Ensure the release valve is fully closed. If the problem persists, the cylinder may require professional inspection and repair. |
For issues not listed here or if solutions do not resolve the problem, contact WilTec customer support or a qualified service technician.
