Key Features to Consider

1. Hydraulic System and Performance
   The hydraulic system on the 953 is one of its standout features. It allows for precise control of lifting, digging, and loading operations. The machine’s lift arm design is robust, ensuring high lifting capacity and minimal hydraulic loss.
   • Hydraulic Capacity: The 953 is equipped with strong hydraulic cylinders that enable it to lift substantial loads, making it suitable for a variety of attachments.
     
   • Attachments Compatibility: A wide range of attachments can be used with the 953, enhancing its versatility in different job applications.
     
2. Bucket and Loading Capacity
   The 953 is commonly paired with a variety of bucket sizes, from general-purpose to specialized designs. The bucket’s size and capacity depend on the machine configuration, but it is capable of handling heavy loads with ease.
   • Bucket Capacity: Typically, the 953's bucket capacity ranges from 1 to 2 cubic yards, making it ideal for heavy lifting and moving materials.
     
   • Material Handling: The 953 performs well in tasks that involve handling earth, rocks, and other materials commonly found in construction sites.
     
3. Track System and Ground Pressure
   The track system is one of the major selling points of the 953. It distributes the weight of the machine across a larger surface area, minimizing ground pressure and allowing it to work in sensitive areas without damaging the ground.
   • Traction: The tracks offer excellent traction on slopes and slippery surfaces.
     
   • Ground Protection: The 953 is less likely to compact the ground compared to wheeled machines, which is beneficial for tasks like grading and leveling.
     

Common Issues to Look Out For When Buying a Used 953

1. Track Wear
   Tracks are a critical component of the 953, and they wear out over time, especially when the machine is used on rough or abrasive surfaces. When buying a used 953, it’s important to inspect the condition of the tracks carefully.
   • Check for Cracks and Wear: Look for signs of cracks, excessive wear, or damage to the track links.
     
   • Track Tension: Ensure the tracks are properly tensioned. Loose or too-tight tracks can cause premature wear and reduced efficiency.
     
2. Hydraulic Leaks or Problems
   Hydraulic issues are another concern for used 953 models. Hydraulic systems can develop leaks or lose pressure, leading to poor performance or even complete system failure.
   • Inspect for Leaks: Check the hoses, cylinders, and fittings for any visible leaks.
     
   • Test Hydraulic Functionality: Operate the hydraulic system during the inspection to make sure the lifting arms and other attachments function smoothly without any hesitation or loss of pressure.
     
3. Engine and Cooling System
   The engine on the 953 is built to last, but like any used machine, it can suffer from wear and tear. Pay attention to any signs of overheating or oil leaks during the inspection.
   • Engine Start-Up: A smooth and quiet engine start is crucial. Listen for any unusual noises during start-up, which could indicate an internal problem.
     
   • Coolant Leaks: Check the radiator and coolant system for any signs of leaks or corrosion.
     
4. Transmission and Drive System
   The 953 uses a hydrostatic transmission system that allows smooth and efficient control of the machine. However, wear in the transmission can cause performance issues, including difficulty in shifting or reduced power delivery.
   • Transmission Test: During the inspection, test the machine’s forward and reverse functions. Ensure the transitions are smooth and that there is no hesitation or grinding.
     
   • Check for Slipping or Delays: Any signs of slipping or delays in power transfer should be addressed immediately.
     
5. Cab and Electrical System
   The cab on the 953 should be checked for wear and tear. Look for any damage to the seat, controls, or safety features. Also, inspect the electrical system to ensure that all lights, gauges, and warning systems are operational.
   • Cab Comfort: Ensure that the seat and controls are in good condition and that the cabin is free from debris or damage.
     
   • Test Electrical Functions: Verify that all electrical systems, such as lights and indicators, are functioning properly.
     

Maintenance Tips for the Caterpillar 953

1. Regular Oil Changes
   Like any heavy equipment, the Caterpillar 953 requires regular oil changes to maintain engine health. Follow the manufacturer’s recommended oil change intervals and use high-quality oil to ensure long engine life.
   
2. Hydraulic System Care
   Regularly check hydraulic fluid levels and inspect for leaks. Keeping the hydraulic system in good condition will prevent expensive repairs and maintain the loader’s performance.
   
3. Track and Undercarriage Maintenance
   To extend the life of the tracks and undercarriage, perform routine checks for wear and adjust the track tension as needed. Replacing worn-out parts promptly will help prevent further damage to the track system.
