Common Issues to Consider When Buying a Used CAT 236 Skid Steer
While the CAT 236 is a reliable piece of equipment, purchasing a used machine requires vigilance. Several common issues could arise with a pre-owned skid steer, and addressing these concerns upfront can prevent expensive repairs in the future.
1. Hydraulic System Problems
Hydraulic system issues are one of the most common concerns in used skid steers. Problems in the hydraulic system can manifest as slow or unresponsive operation of the loader arms, boom, or bucket. Key components to check include:

• Hydraulic Hoses: Look for signs of wear, cracks, or leaks in the hydraulic hoses. Even small leaks can significantly impact performance.
  
• Hydraulic Fluid Levels: Low hydraulic fluid levels can lead to inefficient performance or even cause system failure. Always check the fluid levels and ensure there is no contamination.
  
• Hydraulic Pump: The hydraulic pump is critical for powering attachments and lifting. A failing pump can result in reduced lift capacity or sluggish operations.
  

2. Engine and Transmission Health
The engine and transmission are the heart of the skid steer, and any issues in these areas can lead to costly repairs. When inspecting the used CAT 236, pay attention to:

• Engine Performance: Start the engine and listen for any unusual noises. Smoke or sputtering could indicate underlying engine problems, such as worn-out valves or poor combustion.
  
• Oil Leaks: Inspect the engine and transmission for any oil leaks. Leaking oil can lead to significant damage over time and may indicate seal or gasket issues.
  
• Transmission Functionality: Test the machine in both forward and reverse gears to ensure the transmission is functioning smoothly. Hesitation or slipping could be a sign of worn-out gears or hydraulic issues.
  

3. Undercarriage and Track Condition
The undercarriage is essential for the stability and mobility of the skid steer. A damaged or worn-out undercarriage can lead to expensive repairs. Check the following components:

• Tracks or Tires: Depending on whether the machine has tracks or wheels, check for signs of wear or damage. Worn-out tracks or tires can affect the machine’s performance, leading to poor traction or uneven movement.
  
• Rollers and Idlers: Inspect the rollers and idlers for damage or excessive wear. These components help support the weight of the machine, and any damage could lead to further complications.
  

4. Electrical System Issues
Electrical problems can be challenging to diagnose, but they can cause erratic behavior or complete failure of the machine’s systems. Pay attention to:

• Battery Condition: Ensure the battery is in good condition and properly charged. A weak or dead battery can cause starting issues or erratic electrical performance.
  
• Wiring and Fuses: Inspect the wiring for any exposed, frayed, or damaged wires. Check the fuses to ensure the electrical system is functioning properly.
  

5. Cab and Operator Controls
The operator’s experience is critical for ensuring safety and productivity. When inspecting a used CAT 236, ensure that:

• Operator Comfort: The cab should be free of excessive wear or damage. Check that the seat, controls, and visibility are up to standards.
  
• Control Functionality: Test the controls to ensure that the joystick, pedals, and switches respond smoothly without sticking or malfunctioning.
  

What to Look for During the Inspection Process
When inspecting a used CAT 236 skid steer, it’s essential to take a methodical approach. Below is a checklist of things to review during the inspection:

1. Exterior Condition: Check for any visible signs of damage, rust, or cracks in the frame and body. These issues can affect the machine’s structural integrity.
   
2. Engine and Hydraulic Performance: Start the engine and test all hydraulic functions. Ensure that the machine operates smoothly and there are no unusual sounds or slow movements.
   
3. Fluid Levels and Leaks: Check all fluid levels, including engine oil, hydraulic fluid, and coolant. Look for signs of leaks around hoses, pumps, and the engine.
   
4. Track or Tire Condition: Inspect the tracks or tires for wear. Worn-out tires or tracks will require replacement and can add significant costs.
   
5. Undercarriage Inspection: Look for damage to the rollers, idlers, and other undercarriage components. Any excessive wear should be noted, as these parts can be expensive to replace.
   
6. Cab Condition: Check the operator’s cab for cleanliness and functionality. Ensure all controls are working and there are no issues with the seat, visibility, or air conditioning.
   

Real-World Case Studies and Operator Experiences
Several operators have shared their experiences with the CAT 236 skid steer, noting both positive and negative aspects of the machine. One operator, who purchased a used CAT 236 for a landscaping business, praised the machine for its compact size and maneuverability. They were particularly impressed with how well the skid steer handled in tight spaces and soft terrain, making it a valuable tool for residential landscaping projects.
On the other hand, another operator shared their experience with purchasing a used CAT 236 that had been neglected. They faced numerous hydraulic issues, which required expensive repairs. The operator highlighted the importance of thoroughly inspecting the machine’s hydraulic system and engine before making a purchase, as these components can be costly to repair or replace.
Maintenance Tips for the CAT 236 Skid Steer
To keep your CAT 236 in top condition, regular maintenance is essential. Here are some tips to ensure long-lasting performance:

1. Change Fluids Regularly: Regularly change the engine oil, hydraulic fluid, and coolant to prevent system degradation and ensure smooth operation.
   
2. Monitor the Undercarriage: Regularly inspect the tracks or tires, as well as the rollers and idlers, for wear and damage. Proper maintenance of the undercarriage helps prolong the life of the machine.
   
3. Clean the Air Filter: Check and replace the air filter as needed to ensure the engine receives clean air for optimal performance.
   
4. Grease Moving Parts: Keep all moving components well-lubricated, including the bucket pivot points, arms, and lift cylinders.
   
5. Inspect and Replace Wear Parts: Regularly check parts such as the bucket, hydraulic hoses, and filters for wear. Replace them before they cause major damage to the machine.
