Maintaining the New Holland L185 Cab with a Jack Kit

[MikePhua]

The New Holland L185 is a popular skid steer loader used in a variety of construction and agricultural settings. One of its most important features is its cab, which provides protection for the operator and houses essential controls for the machine’s operation. Over time, however, like any heavy machinery, the cab may require maintenance, including raising it for servicing or repair. This is where a cab jack kit comes in. A cab jack kit is an essential tool that helps operators and maintenance personnel lift and stabilize the cab of the New Holland L185 safely. This article explores the role of the cab jack kit, its importance in maintaining the machine, and best practices for its use.

What is a Cab Jack Kit?
A cab jack kit is a specialized tool designed to lift and hold the cab of a skid steer loader or similar equipment off the frame, providing access to the engine, hydraulic components, and other essential systems. The New Holland L185, like many skid steer models, has a heavy cab that houses the machine’s control system, air conditioning, and other vital components. Lifting the cab is often necessary for deep maintenance tasks, such as engine repairs, hydraulic system servicing, or cleaning components like the radiator or air filters.
The cab jack kit typically consists of adjustable jacks or hydraulic lifts, which provide controlled lifting capabilities. These jacks are placed beneath the cab, allowing the operator to raise it to a sufficient height for easy access while ensuring safety during the process.

Why is a Cab Jack Kit Important?
Using a proper cab jack kit is crucial for several reasons:

1. Safety
   Lifting a heavy cab without the proper equipment can be dangerous. A jack kit ensures that the cab is lifted securely and can be held in place while maintenance is performed. This prevents accidents caused by the cab unexpectedly falling or shifting.
   
2. Efficiency
   Using a jack kit simplifies and speeds up the process of raising the cab. Instead of relying on manual lifting, which may be slow and ineffective, a jack kit provides a stable platform for the cab to rest on while the technician works. This minimizes downtime, especially on busy worksites.
   
3. Preventing Damage
   Improper lifting techniques or using the wrong equipment can result in damage to the cab, frame, or components under the cab. A dedicated jack kit is designed to distribute weight evenly and prevent unnecessary strain on the machinery.
   
4. Access to Critical Components
   The L185’s engine and hydraulic systems are located beneath the cab. Regular maintenance of these systems is essential to the longevity and functionality of the loader. The jack kit allows operators to access these components with ease, ensuring better upkeep and performance.
   

How to Use a Cab Jack Kit
Using a cab jack kit for the New Holland L185 requires care and attention to detail. While the exact procedure may vary slightly depending on the specific model of the kit, the general process is as follows:

1. Prepare the Work Area
   Ensure the loader is parked on a flat, stable surface. Engage the parking brake and place the machine in a neutral position to prevent any movement during the lifting process.
   
2. Position the Jack Kit
   Carefully position the jack kit beneath the cab in the designated lifting points. These points are typically marked in the user manual or service guide of the loader and are designed to bear the weight of the cab without damaging it.
   
3. Lift the Cab
   Gradually lift the cab using the hydraulic jacks or manual cranks provided in the jack kit. Ensure that the lifting process is even, with both sides of the cab being raised at the same time to maintain balance.
   
4. Secure the Cab
   Once the cab is at the desired height, secure it using the safety locks or support struts included in the kit. These will prevent the cab from shifting or lowering unintentionally during maintenance.
   
5. Perform Maintenance
   With the cab securely lifted, technicians can now access the engine, hydraulic pumps, fuel systems, or any other critical components that require attention.
   
6. Lower the Cab
   After the work is complete, carefully lower the cab back into place using the jack kit. Ensure that all safety locks and mechanisms are disengaged before lowering the cab.
   

Common Issues and Troubleshooting with the Cab Jack Kit
While cab jack kits are generally reliable tools, they can face issues from time to time. Here are some common problems and solutions:

1. Hydraulic Leaks
   Over time, hydraulic jack kits can develop leaks, leading to loss of pressure and ineffective lifting. Regularly inspect the hydraulic lines and seals for wear and tear. If a leak is detected, replace the damaged components and top up the hydraulic fluid to ensure proper operation.
   
2. Worn or Damaged Jacks
   The lifting mechanism of the jack kit can wear out over time. If the jacks are not lifting the cab evenly or are struggling to hold the weight, it may indicate internal wear. Inspect the jacks for any signs of damage or rust, and replace them as needed.
   
3. Unstable Cab
   If the cab becomes unstable after lifting, it could be due to improper positioning of the jack kit or incorrect lifting points. Always ensure the lifting points are properly aligned, and check that the jack kit is stable before lifting the cab.
   
4. Slow Lifting Speed
   A slow lifting process can indicate low hydraulic fluid levels or internal issues with the jack kit’s pump. Check the hydraulic fluid levels and top up as necessary. If the issue persists, consult the manufacturer for advice on repairs or replacements.
   

Tips for Extending the Life of the Cab Jack Kit
To ensure that your cab jack kit remains effective over time, it is essential to perform regular maintenance:

1. Clean the Equipment
   After each use, clean the jack kit to remove dirt, debris, and oil buildup. This will help prevent rusting and ensure smooth operation for the next use.
   
2. Store Properly
   When not in use, store the jack kit in a dry, cool environment. Avoid exposing it to extreme temperatures or direct sunlight, as these conditions can cause wear on the materials.
   
3. Lubricate Moving Parts
   Apply lubrication to the moving parts of the jack kit regularly to prevent friction damage. This will help the kit function smoothly and extend its lifespan.
   

Conclusion: The Importance of Proper Equipment for Skid Steer Maintenance
A New Holland L185 skid steer loader is a valuable piece of machinery for any worksite, and keeping it in optimal condition requires regular maintenance. The cab jack kit is an essential tool for servicing the loader’s critical components and should be a part of every operator’s toolkit. By following proper procedures, maintaining the jack kit, and addressing any issues promptly, operators can ensure the longevity of their equipment and minimize downtime. Properly maintaining the cab and its systems will keep the New Holland L185 running efficiently for many years to come.
