The Gehl 6635 is a versatile skid steer loader used in various construction applications. However, over time, users may encounter issues with the hydraulic system, particularly with the tilt cylinder. For operators with little experience, correctly repacking the tilt cylinder can be a challenge. This article provides essential guidance on repacking the tilt cylinder of the Gehl 6635.
Signs of Tilt Cylinder Failure
Tilt cylinder failure often presents itself through the following symptoms:
If you choose to repack the tilt cylinder on your Gehl 6635, follow these necessary steps:
Repacking the tilt cylinder on a Gehl 6635 skid steer loader, though challenging for an inexperienced operator, is manageable with the right tools and instructions. Addressing tilt cylinder leakage or failure promptly will enhance machine performance and prolong its lifespan.
Signs of Tilt Cylinder Failure
Tilt cylinder failure often presents itself through the following symptoms:
- Oil Leakage: When the seals inside the cylinder wear out or become damaged, hydraulic oil may leak, resulting in a drop in system pressure.
- Stiff or Unresponsive Operation: A malfunctioning tilt cylinder may cause sluggish or uneven tilting of the loader during operation.
- Increased Noise: Leaking hydraulic oil or damage within the cylinder can introduce air bubbles into the system, causing unusual noises during operation.
If you choose to repack the tilt cylinder on your Gehl 6635, follow these necessary steps:
- Prepare Tools and Materials: Ensure you have the proper tools, including wrenches, bolt removal tools, hydraulic oil, and a seal kit specifically designed for the Gehl 6635.
- Remove the Tilt Cylinder: First, shut off the hydraulic system and relieve any built-up pressure. Secure the loader with support equipment to prevent the cylinder from falling during removal.
- Disassemble the Cylinder Components: Use wrenches and other tools to disassemble the various parts of the cylinder. Take special care when removing seals and pistons, ensuring no parts are damaged in the process.
- Inspect Damaged Parts: Check both the internal and external components of the cylinder, including the piston, seals, and cylinder body. If any parts are severely worn or damaged, replace them.
- Install New Seals: Replace the worn seals with the new ones from the seal kit. Make sure the seals are installed correctly to prevent further leakage, and avoid damaging them during installation.
- Reassemble the Cylinder: Reassemble all the parts of the cylinder in the reverse order of disassembly. Ensure all components are tightened securely and that nothing is left loose.
- Reinstall the Cylinder: Place the repacked tilt cylinder back into the Gehl 6635 hydraulic system. Double-check that all connections are tight, and ensure no hydraulic lines are leaking.
- Test and Inspect: Start the hydraulic system and test the cylinder’s operation. Check that the tilt cylinder functions smoothly without any leaks or operational issues.
- Safety First: Always disconnect the power supply and relieve hydraulic system pressure before starting any repair work to ensure safety during the process.
- Professional Help: If you are uncertain about the repair process or encounter difficulties during disassembly, it is advisable to seek professional assistance. Incorrect procedures could lead to further damage or hydraulic system failures.
- Routine Maintenance: To prevent future tilt cylinder failure, regularly inspect the hydraulic system, keep hydraulic oil clean, and replace seals as needed. Proper maintenance ensures long-term performance.
Repacking the tilt cylinder on a Gehl 6635 skid steer loader, though challenging for an inexperienced operator, is manageable with the right tools and instructions. Addressing tilt cylinder leakage or failure promptly will enhance machine performance and prolong its lifespan.
