A Comprehensive Guide to Buying and Maintaining a 1988 CAT 953: A Case Study
#1
When purchasing heavy equipment, especially older models, several factors must be considered to ensure the investment is sound and the machine will continue to perform well for years to come. One such purchase is the 1988 CAT 953, a versatile and well-regarded track loader. This article provides an in-depth look at the purchase and maintenance of a 1988 CAT 953, focusing on the potential challenges and the steps needed to ensure long-term reliability and productivity.
Overview of the CAT 953
The CAT 953 track loader, a popular model from Caterpillar, was built for versatility, strength, and efficiency. These loaders are capable of performing various tasks, including material handling, grading, and digging, thanks to their robust hydraulics and strong undercarriage. Manufactured in the late 1980s, the 953 is powered by a powerful diesel engine, making it suitable for demanding construction and excavation projects. Even though the 953 is nearly 40 years old, it remains an excellent machine when properly maintained.
Buying a Used 1988 CAT 953: Key Considerations
Purchasing any used heavy equipment requires due diligence, especially when the machine in question is several decades old. When buying a 1988 CAT 953, the buyer must consider the following:
  1. Age and Hours
    • The 1988 CAT 953 is a machine with substantial history. Given its age, checking the number of hours the machine has been in operation is essential. Hours indicate wear and tear and help gauge how much work the machine has left before major repairs or overhauls are needed. A well-maintained 953 with fewer hours can still provide reliable service, but higher-hour machines might require more immediate attention.
  2. Condition of the Tracks and Undercarriage
    • The undercarriage and tracks are among the most crucial components of any tracked loader. A worn-out undercarriage can be costly to repair or replace. Buyers should inspect the condition of the tracks, sprockets, rollers, and idlers. In particular, check for signs of excessive wear, cracks, or leaks. Replacing the undercarriage can cost thousands of dollars, so understanding its current condition is key.
  3. Engine and Hydraulics
    • The heart of any loader is its engine. The 1988 CAT 953 is equipped with a reliable diesel engine, but it’s important to verify its operational condition. Buyers should request service records, inspect the engine for oil leaks, check the exhaust system for smoke or unusual sounds, and assess its overall power output.
    • The hydraulic system is another area that requires careful inspection. The 953 uses hydraulics for both lifting and digging operations, and hydraulic failures can quickly reduce productivity. Check for any fluid leaks around the hoses, cylinders, and pumps. Ensure the hydraulic fluid is clean and at the proper level.
  4. Transmission and Steering
    • The transmission and steering systems of the CAT 953 are vital to the smooth operation of the loader. Be sure to test the transmission for smooth shifting and ensure there are no unusual grinding sounds. The steering mechanism should also be responsive, and any play or hesitation should be addressed.
  5. Cab and Operator Comfort
    • The operator’s comfort is essential for long hours of use, so inspect the cab for proper ergonomics. Check the condition of the seat, controls, visibility, and climate control system. Given the age of the machine, the cab may show signs of wear, but the functionality and comfort should not be compromised.
Common Issues with Older CAT 953 Models
Even though the 1988 CAT 953 is known for its reliability, certain common issues may arise as the machine ages. Understanding these potential issues can help buyers make informed decisions and be prepared for maintenance:
  1. Hydraulic Cylinder Leaks
    • As the loader ages, the hydraulic cylinders may develop leaks. This is a common issue in older machines and requires timely repair to prevent loss of power. Rebuilding or replacing the hydraulic cylinders can be costly, but it is crucial for maintaining the loader’s performance.
  2. Engine Overheating
    • Engine overheating can be a concern for older models. The cooling system should be checked regularly for signs of wear, and coolant levels should be maintained. If the engine shows signs of overheating, it may indicate a problem with the radiator or the water pump.
  3. Undercarriage Wear
    • Track wear and undercarriage issues are common in used track loaders. As the 953 is designed for tough work, the undercarriage may need repairs or replacement. Track tension, wear patterns, and the condition of the rollers must be closely monitored to ensure smooth operation.
  4. Electrical Issues
    • As machines age, electrical components may begin to fail. Wiring issues, blown fuses, and malfunctioning sensors are common problems in older CAT 953 models. A thorough inspection of the electrical system can help identify and address issues before they cause significant disruptions.
Maintenance Tips for the 1988 CAT 953
Proper maintenance is the key to keeping any piece of heavy equipment running smoothly, and the CAT 953 is no exception. Regular care and attention will ensure that the loader remains in good working condition for years to come:
  1. Routine Fluid Checks and Changes
    • Regularly check engine oil, hydraulic fluid, and coolant levels. Clean oil is essential for engine and hydraulic health, and routine oil changes will prolong the life of the engine and hydraulic system.
  2. Track and Undercarriage Inspection
    • Inspect the tracks and undercarriage for signs of wear, damage, and leaks. Pay particular attention to the tension of the tracks, as improperly adjusted tracks can cause excessive wear and strain on other components. Consider greasing the undercarriage regularly to prevent rust and ensure smooth operation.
  3. Hydraulic System Care
    • Keep an eye on the hydraulic system, particularly the hoses and cylinders. Leaks should be addressed immediately to prevent further damage. Additionally, ensure the hydraulic fluid is kept at the proper level and replaced at intervals recommended by the manufacturer.
  4. Engine Maintenance
    • The CAT 953's diesel engine requires regular maintenance, including oil changes, air filter replacement, and fuel filter checks. Keep the engine cool by maintaining the radiator and ensuring the cooling system is free from blockages.
  5. Electrical System Checks
    • Inspect the electrical components, including the battery, alternator, and wiring, regularly. Keep the battery terminals clean and free from corrosion. Ensure the charging system is working properly to avoid issues with power during operation.
  6. Operator Training
    • The condition of the machine is directly affected by how it is operated. Ensure that operators are properly trained in how to handle the machine efficiently. Proper operation reduces the risk of damage and extends the machine's lifespan.
The Value of the 1988 CAT 953 Today
While the 1988 CAT 953 is considered an older model, it still holds significant value in certain applications. The machine’s robust build and versatility make it a good choice for smaller construction projects, landscaping, and material handling tasks. Its relatively simple design compared to modern machines also means that it can be repaired and maintained more affordably, making it an attractive option for contractors working on a budget.
Moreover, the CAT 953 has built a reputation for reliability, and many still use it on the job today. As long as it is properly maintained, a 1988 CAT 953 can provide many more years of reliable service.
Conclusion
The 1988 CAT 953 is a powerful and reliable track loader that has stood the test of time. While purchasing an older model requires thorough inspection and maintenance, the CAT 953 remains an excellent choice for operators looking for a solid, versatile machine. By paying close attention to common issues, performing regular maintenance, and addressing problems early, a 1988 CAT 953 can continue to serve effectively for many years. For those willing to invest the time and effort into caring for it, this iconic machine is a valuable asset in the world of heavy equipment.
