What to Look for When Buying a Used Bobcat 743 Skid Steer

[MikePhua]

The Bobcat 743 skid steer loader is a classic piece of equipment, known for its efficiency and versatility across construction, agriculture, and various other industries. However, when purchasing a used Bobcat 743, it's essential to pay attention to certain key areas to ensure the machine is in good working condition and will meet your needs. This article outlines the critical factors to consider when buying a used Bobcat 743.
Check the Engine Condition

1. Engine Starting and Running Smoothness
   When purchasing a used Bobcat 743, the first thing to check is how smoothly the engine starts. Difficulty starting or rough running could indicate engine problems. Ensure there are no unusual sounds, such as knocking or rattling, which might suggest internal engine issues.
   
2. Inspect the Engine Oil and Coolant
   Check the condition of the engine oil and coolant. If the engine oil is dirty or discolored, it may signal poor maintenance. Additionally, ensure there are no coolant leaks, as overheating could be a concern for engine longevity.
   

Check the Hydraulic System

1. Hydraulic Fluid and Pressure
   The hydraulic system is one of the most critical components of the Bobcat 743. It’s important to check the color and quality of the hydraulic fluid. If the fluid is black or cloudy, it could indicate contamination or leakage in the system. Performing a pressure test on the hydraulic system is also crucial to ensure the smooth movement of the arms, bucket, and other hydraulic components.
   
2. Inspect the Hydraulic Pump and Hoses
   Make sure the hydraulic pump is functioning properly and check for any oil leaks around the system. The hydraulic hoses should also be intact to avoid loss of hydraulic pressure or system failure.
   

Check the Tracks and Tires

1. Track Wear
   Inspect the wear on the skid steer’s tracks. Excessive wear can affect the machine's traction and stability. Ensure that the track tension is correct, avoiding it being too tight or too loose. Also, check the track’s connection pins for any looseness, as a loose connection can impact performance.
   
2. Tire Wear and Pressure
   For models with tires, inspecting the wear is equally important. Uneven tire wear could be due to suspension issues or improper tire pressure. Ensure that the tire pressure is correct to extend their lifespan.
   

Check the Electrical System

1. Battery and Wiring
   Inspect the battery condition and the integrity of the wiring. An old or worn-out battery, or loose electrical connections, could cause starting problems and lead to electrical system malfunctions. Verify the battery voltage to ensure it's sufficient for starting the engine and powering other electrical components.
   
2. Lights and Gauges
   Ensure that all lights and gauges are working properly. Check the control panel for any abnormal indicator lights, especially those related to hydraulic, oil pressure, or temperature.
   

Inspect the Exterior and Structure

1. Casing and Hinges
   Check the exterior for any cracks, rust, or physical damage. The hinges and locks should also be inspected to ensure they are not loose or damaged. Any structural damage could compromise the safety and stability of the equipment.
   
2. Service History
   Ask for the machine's service history, including any past accidents, maintenance records, and operating environment. If possible, obtain maintenance and repair records to get a clearer picture of the machine's true condition.
   

Conclusion
When buying a used Bobcat 743 skid steer, it's crucial to thoroughly inspect the engine, hydraulic system, tracks and tires, electrical system, and the exterior for any wear or damage. By carefully evaluating these key areas, you can ensure that you are purchasing a well-maintained machine that will meet your needs and avoid expensive repairs in the future. By making a careful selection and verifying the equipment's condition, you'll be able to find a reliable and cost-effective used Bobcat 743 to support your projects.
