The 953 is designed for demanding tasks that require lifting, digging, and hauling materials. Its compact design makes it ideal for working in tight spaces, while its powerful engine ensures that it can handle heavy loads and tough terrains.
Here are some features that make the 953 a versatile machine:
- Powerful Engine Performance
The 953 comes with a 4.4L diesel engine that provides the power needed to lift and move heavy materials. This engine is known for its longevity and ability to perform under heavy loads, making it a reliable choice for various applications.
- Hydraulic System Efficiency
The hydraulic system in the 953 is another reason for its strong reputation. With efficient hydraulic controls, the loader can handle a wide range of attachments, from buckets to grapples, and perform tasks that require precision.
- Durability and Versatility
Built with a robust chassis and powerful undercarriage, the 953 is designed to withstand tough working conditions. Whether it’s handling dirt, sand, or rocks, the 953 can perform various tasks with ease. Its versatility also makes it suitable for both light and heavy-duty work.
While the Caterpillar 953 is known for its durability, like any older piece of equipment, it can have its share of problems. Understanding these common issues can help new owners troubleshoot and fix the machine effectively.
- Hydraulic Problems: Slow Operation and Leaks
One of the most common problems reported by 953 owners is issues with the hydraulic system. If you notice slow operation or a decrease in power while using the loader’s bucket or other attachments, it could indicate a hydraulic leak or an issue with the hydraulic pump.- Solution: Check for visible leaks around the hydraulic lines and connections. Inspect the hydraulic filter and fluid levels as well. Low fluid or dirty filters can impair the system’s function. If the problem persists, it might be necessary to replace the hydraulic pump or valves.

- Engine Overheating
Overheating can be a major concern for any heavy equipment. If the 953 begins to overheat, it could be due to issues with the cooling system, such as a clogged radiator, damaged thermostat, or low coolant levels.- Solution: Regularly inspect the radiator and cooling system for any debris or blockages that could impede airflow. Check the coolant levels and ensure the thermostat is functioning properly. It’s also important to clean the radiator fins to ensure optimal heat dissipation.

- Starting Problems and Electrical Issues
Another common issue with older equipment is difficulty starting the engine, often related to electrical issues. If the 953 struggles to start or if the starter motor fails to engage, there may be an issue with the battery, wiring, or the starter itself.- Solution: First, check the battery voltage and clean the terminals to ensure proper connection. If the battery is fine, inspect the wiring for corrosion or loose connections. The starter motor and solenoid should also be checked for proper functionality.

- Transmission and Undercarriage Issues
The 953’s transmission and undercarriage are vital to its overall performance. Issues such as slipping gears, jerky movements, or difficulty shifting can indicate problems with the transmission or final drive system. Similarly, excessive wear on the undercarriage components can lead to a rough ride or loss of traction.- Solution: Check the transmission fluid for proper levels and quality. If the fluid is dirty or low, replace it. For undercarriage problems, inspect the tracks, rollers, and sprockets for signs of wear or damage. Worn undercarriage components should be replaced to ensure optimal performance.

- Bucket or Attachment Malfunctions
If the loader’s attachments are not functioning as expected—whether it’s a problem with lifting, tilting, or operation—it could be due to issues with the attachment hydraulics, pins, or linkage.- Solution: Inspect the attachment hydraulics for leaks or blockages. Check the pins and linkage for wear, and lubricate them regularly. If the attachment is not operating properly, ensure that the hydraulic lines are not obstructed and that the flow rates are sufficient.

Regular maintenance is key to extending the life of the Caterpillar 953 and avoiding costly repairs. Here are some maintenance tips to keep your 953 running smoothly:
- Oil Changes and Engine Maintenance
Regularly change the engine oil to keep the engine running smoothly. Follow the manufacturer’s guidelines for oil change intervals, usually every 250 hours of operation. Also, inspect the air filters and replace them as necessary to ensure that the engine is getting enough clean air for combustion.
- Hydraulic System Maintenance
Keep the hydraulic fluid at the proper levels and change it regularly to prevent overheating and damage to the hydraulic components. Check the hydraulic filters for contamination and replace them periodically. Flushing the hydraulic system at regular intervals can prevent build-up and ensure optimal performance.
- Undercarriage Inspection
Since the 953 is a tracked machine, it’s essential to regularly inspect the undercarriage for wear. Check the tracks for tension and proper alignment. Ensure that the sprockets, rollers, and idlers are in good condition. Replace worn components promptly to avoid further damage.
- Cooling System Checks
Overheating is a common issue with older machines, so maintaining the cooling system is essential. Regularly check the radiator for blockages and clean the fins to allow for better airflow. Ensure that the coolant levels are sufficient and that the system is free of leaks.
- Tire and Track Care
If your 953 has wheels, inspect the tires for proper inflation and wear. For tracked machines, ensure that the tracks are properly aligned, and check for excessive wear. Uneven wear on the tracks can affect the loader’s stability and performance, so regular maintenance is critical.
