The undercarriage is a critical area to assess, as its condition directly impacts the machine's stability and mobility. Check the tracks, rollers, sprockets, and idlers for wear and damage. The operator cab should be inspected for functionality of controls and instrumentation. It's also important to obtain the machine's maintenance history, if available, to understand how well it has been cared for. Finally, consider the asking price in relation to the machine's condition and market value.
Inspection Checklist for a Cat 235
Before committing to purchase, a comprehensive inspection is crucial. Here's a checklist to guide you:
- Engine: Check for leaks, smoke, unusual noises, and overall performance.
- Hydraulic System: Inspect hoses, cylinders, pumps, and valves for leaks or damage. Ensure smooth and responsive operation.
- Undercarriage: Assess the condition of tracks, rollers, sprockets, and idlers. Measure track wear to estimate remaining life.
- Operator Cab: Verify functionality of controls, gauges, and safety devices. Check for damage or wear to seats and interior.
- Boom and Stick: Inspect for cracks, bends, and wear at pivot points. Check cylinder seals for leaks.
- Swing Mechanism: Evaluate smoothness and stability during rotation. Listen for unusual noises.
- Overall Structure: Look for signs of cracks, welds, or previous repairs on the frame and chassis.

Common Issues and Repairs
Like any machine, the Cat 235 excavator is susceptible to certain common issues and repairs. Hydraulic leaks are a frequent concern, often stemming from worn seals or damaged hoses. Undercarriage wear is inevitable, requiring periodic replacement of tracks, rollers, and other components. Engine problems can arise from lack of maintenance or excessive use, leading to decreased performance or failure. Electrical issues, while less common, can affect the machine's starting system or instrumentation. The boom and stick are also vulnerable to damage from impacts or heavy loads, potentially requiring welding or component replacement. Addressing these issues promptly is crucial to maintaining the machine's productivity and extending its lifespan. Regular inspections and preventative maintenance can help minimize the occurrence of these problems.
Pricing and Availability
The price of a used Cat 235 excavator can vary significantly depending on its age, condition, and location. Generally, older machines with higher hours will be priced lower than newer, well-maintained units. Market demand also plays a role in determining price. Researching recent sales of similar machines can provide a good benchmark for evaluating the asking price. Availability can also fluctuate depending on the region and the current economic climate. Online marketplaces, auction sites, and dealerships are all potential sources for finding a Cat 235 excavator for sale. Be prepared to negotiate the price based on your assessment of the machine's condition and value. Remember to factor in transportation costs when considering machines located far from your job site.
