What to Consider When Buying a Used 955L
While the CAT 955L is known for its durability, like any used equipment, it is essential to carefully evaluate the condition of the machine before making a purchase. Here are a few important factors to assess:
1. Engine Condition and Hours
The engine is the heart of any heavy machinery, and in the case of the 955L, the CAT 3306 engine has proven to be a reliable workhorse. However, as with any diesel engine, it's crucial to check for signs of wear or excessive hours. A well-maintained engine should have a smooth start, consistent power delivery, and minimal emissions. Look at the engine hours, and if possible, request a service history to verify how well the engine has been maintained.
Additionally, check for signs of oil leaks, unusual engine noise, and check the oil levels to ensure they are within normal ranges. If the machine has had a lot of hours or hard use, you may want to budget for an engine overhaul in the near future.
2. Hydraulic System
The 955L's hydraulic system is crucial for its performance, especially when lifting and operating various attachments. Check for any signs of leaks in the hydraulic hoses and cylinders. The hydraulic fluid should be clean, and there should be no visible signs of contamination. If the hydraulic system is sluggish or unresponsive, it could indicate worn components or leaks that would require costly repairs.
3. Track and Undercarriage Condition
Being a track loader, the undercarriage is an area that requires particular attention. Inspect the tracks for wear, cracks, or excessive stretching. The undercarriage components such as the rollers, idlers, and sprockets should also be checked for damage or signs of excessive wear. If the tracks are in poor condition, you’ll need to factor in the cost of replacement tracks and undercarriage components.
4. Cab and Operator Comfort
The operator’s cabin in older machines like the CAT 955L may not offer the same level of comfort and technology found in modern machines, but it should still provide a safe and functional working environment. Check the seat, controls, and visibility to ensure they are comfortable for long working hours. Additionally, ensure that the air conditioning and ventilation systems work if the machine is equipped with them.
5. Transmission and Steering System
The mechanical transmission in the 955L is designed to be robust, but it’s important to check for smooth shifting and any signs of slippage. In addition, the hydrostatic steering should be responsive and free from any jerking or unusual resistance. If the steering is stiff or the transmission is sluggish, it may indicate the need for repairs or adjustments.
6. Overall Maintenance and Service History
A machine with a well-documented service history is always a safer bet than one with an unclear past. Ask the seller for maintenance records to see if the machine has had regular servicing, including oil changes, hydraulic fluid replacement, and any major repairs or replacements. Machines that have been regularly maintained are likely to have a longer useful life and fewer unexpected breakdowns.
Pros and Cons of the CAT 955L
Pros:

• Durability: The 955L is known for its sturdy build and long-lasting performance, especially in tough working conditions.
  
• Versatility: It is capable of performing a variety of tasks, from lifting and loading to excavation.
  
• Fuel Efficiency: The 3306 engine is relatively fuel-efficient for the power it provides, which can be a major factor in reducing operational costs.
  

Cons:

• Age of the Model: As a model introduced in the 1960s, parts may be harder to find, and some machines may have a lot of wear.
  
• Operator Comfort: Compared to newer machines, the 955L may lack modern features such as improved suspension, air conditioning, and advanced control systems.
  
• Limited Attachment Options: While the 955L can use a variety of attachments, the selection may not be as extensive as more modern track loaders.
  

Conclusion
The CAT 955L remains a popular choice among those looking for a powerful, reliable track loader capable of handling tough jobs. Whether you're considering a used model or looking to learn more about its capabilities, this machine offers a great balance of power and versatility.
When purchasing a used 955L, the most important factors to consider are engine condition, the hydraulic system, undercarriage wear, and the machine's overall maintenance history. By carefully assessing these components, you can make an informed decision and ensure that you’re investing in a machine that will deliver long-term value and productivity. With the right care and maintenance, a CAT 955L can serve you well for many years.
