1. Introduction
This manual provides essential instructions for the proper installation, operation, and maintenance of the Morgan Maxon 266037-01 OEM Cylinder Assembly. This hydraulic cylinder is designed for specific liftgate applications, including models S204T-3785 and S204T-3795. Adherence to these guidelines is crucial for ensuring safe and efficient performance and extending the product's lifespan. Please read this manual thoroughly before attempting any procedures.
2. Safety Information
Always observe the following safety precautions to prevent injury to personnel and damage to equipment:
- Professional Installation: Installation and maintenance should only be performed by qualified personnel with experience in hydraulic systems.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses, gloves, and protective clothing, when handling hydraulic components.
- System Depressurization: Before performing any work on the hydraulic system, ensure all pressure is relieved. High-pressure fluid can cause severe injury.
- Fluid Handling: Hydraulic fluid can be hazardous. Avoid skin contact and follow manufacturer's guidelines for safe handling and disposal.
- Correct Components: Use only genuine OEM replacement parts to ensure compatibility and system integrity.
- Secure Mounting: Ensure the cylinder is securely mounted according to the liftgate manufacturer's specifications to prevent accidental detachment.

Key Features:
- OEM quality for direct fit and reliable performance.
- Durable construction suitable for demanding liftgate operations.
- Designed for compatibility with Maxon liftgate models S204T-3785 and S204T-3795.
4. Setup and Installation
Installation of the hydraulic cylinder assembly requires specialized knowledge and tools. It is strongly recommended that this procedure be performed by a certified technician or authorized service center.
4.1 Pre-Installation Checks:
- Verify that the received cylinder assembly matches the required part number (266037-01) for your Maxon liftgate model.
- Inspect the cylinder for any signs of shipping damage. Do not install damaged components.
- Ensure all necessary tools, hydraulic fluid, and safety equipment are available.
4.2 Installation Steps (General Guidelines):
- Prepare the Liftgate: Safely support the liftgate platform in a secure position. Depressurize the hydraulic system completely.
- Remove Old Cylinder: Disconnect hydraulic lines and mounting pins from the old cylinder. Collect any spilled hydraulic fluid.
- Mount New Cylinder: Position the new 266037-01 cylinder assembly and secure it using the appropriate mounting pins and hardware. Ensure proper alignment.
- Connect Hydraulic Lines: Carefully connect the hydraulic lines to the cylinder ports. Ensure all connections are tight and free from leaks. Use appropriate thread sealant if required by the liftgate manufacturer.
- Fill and Bleed System: Refill the hydraulic reservoir with the recommended fluid type. Bleed air from the hydraulic system according to the liftgate manufacturer's instructions.
- Test Operation: Slowly cycle the liftgate through its full range of motion, checking for smooth operation, leaks, and correct functionality. Monitor fluid levels.
5. Operating Principles
The 266037-01 cylinder assembly operates as part of the liftgate's hydraulic system. Hydraulic fluid, pressurized by a pump, is directed into the cylinder to extend or retract the piston rod, thereby moving the liftgate platform. Proper operation relies on:
- Clean Hydraulic Fluid: Use only the type and grade of hydraulic fluid specified by the liftgate manufacturer. Contaminated fluid can damage seals and internal components.
- Correct System Pressure: The hydraulic system must operate within the pressure range specified by the liftgate manufacturer. Excessive pressure can lead to component failure.
- Smooth Movement: The cylinder should extend and retract smoothly without jerking or unusual noises.
6. Maintenance
Regular maintenance is essential for the longevity and reliable operation of the cylinder assembly. Refer to your liftgate's specific maintenance schedule for detailed intervals.
6.1 Routine Checks:
- Visual Inspection: Periodically inspect the cylinder for external leaks, corrosion, or physical damage to the barrel, rod, and mounting points.
- Hydraulic Fluid Level: Check the hydraulic fluid level in the reservoir regularly and top up as needed with the specified fluid.
- Hose and Fitting Integrity: Inspect hydraulic hoses and fittings for wear, cracks, or leaks. Tighten connections as necessary.
- Mounting Hardware: Ensure all mounting pins and bolts are secure and properly torqued.
6.2 Cleaning:
Keep the exterior of the cylinder clean to prevent dirt and debris from entering the seals. Use a mild detergent and water, avoiding harsh chemicals that could damage seals or paint.
7. Troubleshooting
This section provides general guidance for common issues. For complex problems, consult a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Cylinder not extending/retracting | Low hydraulic fluid level, air in system, faulty pump, clogged filter, control valve issue. | Check fluid level and add if necessary. Bleed the system. Inspect pump and filter. Consult liftgate manual for control valve diagnostics. |
| Slow or erratic movement | Low fluid level, air in system, worn seals, incorrect fluid viscosity, partial blockage. | Check fluid level and bleed system. Inspect for external leaks indicating worn seals. Verify correct fluid type. |
| External fluid leaks | Damaged seals (rod or piston), loose fittings, cracked hose. | Identify source of leak. Tighten fittings. Replace damaged seals or hoses. This often requires professional service. |
| Unusual noises (e.g., grinding, squealing) | Air in system, cavitation, worn bearings in pump, mechanical interference. | Bleed the hydraulic system. Inspect for proper mounting and clearance. Consult a technician for pump inspection. |
