Dealing with a busted lift cylinder pipe on a CAT 953C loader can be a challenging task, but understanding the symptoms, potential causes, and how to repair or replace the damaged parts can make the process smoother and more efficient.
Identifying the Problem
A common issue with the CAT 953C loader is a busted or damaged lift cylinder pipe. This problem usually results in hydraulic fluid leaks, reduced lifting capacity, and potentially unsafe operation. When this issue arises, the loader may show signs of a weak or slow lifting action, or you may notice hydraulic fluid pooling around the cylinder area.
Common Causes of Pipe Damage
Repairing a busted lift cylinder pipe on a CAT 953C requires a thorough understanding of the machine’s hydraulic system. By diagnosing the problem, taking the necessary steps to repair or replace the pipe, and performing regular maintenance, you can extend the lifespan of the loader and ensure it operates efficiently for years to come.

Common Causes of Pipe Damage
- Hydraulic Pressure Fluctuations
The hydraulic system of the CAT 953C operates under high pressure, and fluctuations in pressure can cause stress on the lift cylinder pipes. Over time, this stress can lead to cracking, bending, or complete failure of the pipes.
- Corrosion
Exposure to the elements, particularly if the loader is frequently used in harsh conditions, can cause corrosion of the hydraulic pipes. Saltwater, chemicals, and dirt can accelerate the rusting process, leading to pipe degradation and eventual failure.
- Mechanical Impact or Stress
If the loader is involved in heavy lifting or is subjected to harsh impacts, the lift cylinder pipes can be bent or broken. This could be the result of using the machine improperly or pushing the loader beyond its capacity.
- Diagnose the Exact Location of the Damage
The first step in repairing the busted pipe is to locate the exact damage. Inspect the lift cylinder and the associated pipes for visible cracks or leaks. It's important to check the connections and seals around the pipe to determine if the damage is isolated or if there’s a larger issue within the hydraulic system.
- Drain the Hydraulic Fluid
Before performing any repairs, ensure that the hydraulic fluid is safely drained from the system. This prevents further contamination or spills during the repair process and ensures that no pressure is on the damaged pipe when you begin work.
- Disassemble the Affected Components
To replace the busted pipe, you’ll need to disassemble the hydraulic components connected to the lift cylinder. This includes removing any hoses, fasteners, and components blocking access to the pipe.
- Replace or Weld the Damaged Pipe
If the pipe is severely damaged or cracked, the best solution is to replace it with a new one. In some cases, the pipe may be able to be welded or patched if the damage is minor. Ensure that any replacement parts meet the exact specifications of the original parts to maintain the loader’s performance.
- Reassemble and Test the System
After replacing or repairing the damaged pipe, carefully reassemble all the parts. Make sure that all connections are tight and that no leaks remain. Refill the hydraulic system with fresh fluid and test the loader to ensure that the lift cylinder is functioning correctly.
- Regular Inspections
To prevent future issues with the lift cylinder pipes, it’s essential to perform regular inspections of the hydraulic system. Look for signs of wear, leaks, or corrosion, and address these issues promptly.
- Avoid Overloading the Machine
The CAT 953C is a powerful loader, but overloading it can put undue stress on the lift cylinders and pipes. Always follow the recommended weight limits and guidelines for the loader’s operation.
- Use High-Quality Hydraulic Fluid
Using the right hydraulic fluid helps reduce wear and tear on the system, keeping the pipes and cylinders functioning smoothly.
