Understanding the Lift and Tilt Mechanism
Before delving into troubleshooting, it is essential to understand how the lift and tilt functions operate on the Bobcat T200.
- Lift Function
- The lift function is powered by the hydraulic system, allowing the arms of the skid steer to raise and lower. The hydraulic pump delivers pressurized fluid to the lift cylinders, enabling them to lift and lower the boom arms and the attached load.

- Tilt Function
- The tilt function, which controls the bucket's angle, is also hydraulically driven. It allows the operator to tilt the bucket forward or backward to scoop, dump, or level materials. This is a crucial function for various tasks like grading or material handling.

Common Causes of Lift and Tilt Failures
Several factors can cause the lift and tilt functions on the Bobcat T200 to stop working. These issues can range from minor fixes to more complex mechanical repairs. Below are the most common causes of such failures:
- Low Hydraulic Fluid Levels
- Cause: One of the most common causes of hydraulic system malfunctions is low hydraulic fluid levels. If the fluid is below the required level, there won’t be enough pressure in the system to power the lift and tilt functions.
- Symptoms: The lift and tilt may move slowly, jerk or not function at all.
- Solution: Check the hydraulic fluid reservoir for the correct level. If it’s low, top it off with the manufacturer-recommended hydraulic fluid. If low fluid levels persist, check for leaks in the system that might be causing the fluid loss.
- Cause: One of the most common causes of hydraulic system malfunctions is low hydraulic fluid levels. If the fluid is below the required level, there won’t be enough pressure in the system to power the lift and tilt functions.
- Hydraulic Fluid Contamination
- Cause: Contaminants such as dirt, water, or metal particles in the hydraulic fluid can clog filters and affect the performance of hydraulic components, including the lift and tilt cylinders.
- Symptoms: The lift and tilt functions may become sluggish, noisy, or unresponsive.
- Solution: If contamination is suspected, change the hydraulic fluid and replace the filters. Clean or flush the hydraulic lines to remove contaminants. Ensure that the fluid is of the proper type and clean when refilling.
- Cause: Contaminants such as dirt, water, or metal particles in the hydraulic fluid can clog filters and affect the performance of hydraulic components, including the lift and tilt cylinders.
- Faulty Hydraulic Pump
- Cause: The hydraulic pump is responsible for delivering pressurized fluid to the hydraulic cylinders. A malfunctioning or damaged pump can result in inadequate pressure, causing the lift and tilt functions to fail.
- Symptoms: The machine may make a whining or grinding noise when the lift or tilt is operated. There may also be a noticeable decrease in hydraulic power.
- Solution: Check the hydraulic pump for damage or wear. If the pump is faulty, it may need to be replaced. Be sure to consult the user manual for the correct specifications and procedures when replacing the pump.
- Cause: The hydraulic pump is responsible for delivering pressurized fluid to the hydraulic cylinders. A malfunctioning or damaged pump can result in inadequate pressure, causing the lift and tilt functions to fail.
- Damaged Hydraulic Cylinders
- Cause: The hydraulic cylinders that control the lift and tilt functions are essential for transferring the pressure needed to operate the arms and bucket. Damage or wear in these cylinders, such as leaks or bent rods, can result in a loss of hydraulic power.
- Symptoms: The lift or tilt movements may be uneven, weak, or entirely non-functional.
- Solution: Inspect the hydraulic cylinders for any signs of external damage, leaks, or bent components. If the cylinder is damaged, it may need to be replaced or repaired. Ensure that seals are intact to prevent fluid leaks.
- Cause: The hydraulic cylinders that control the lift and tilt functions are essential for transferring the pressure needed to operate the arms and bucket. Damage or wear in these cylinders, such as leaks or bent rods, can result in a loss of hydraulic power.
- Faulty Control Valve
- Cause: The control valve directs hydraulic fluid to the appropriate cylinders for the lift and tilt functions. A malfunctioning valve can prevent the fluid from reaching the right components, thus hindering movement.
- Symptoms: Unresponsiveness or erratic behavior in the lift or tilt controls.
- Solution: Inspect the control valve and its solenoids for proper function. Ensure that the valve is not clogged or stuck. If faulty, the valve may need to be repaired or replaced.
- Cause: The control valve directs hydraulic fluid to the appropriate cylinders for the lift and tilt functions. A malfunctioning valve can prevent the fluid from reaching the right components, thus hindering movement.
- Electrical or Control Circuit Problems
- Cause: The T200’s lift and tilt functions are controlled electronically by switches and relays. A failure in the electrical system, such as a blown fuse or malfunctioning relay, can prevent the hydraulic valves from being activated.
- Symptoms: The lift or tilt control may not respond, or the machine may display error codes on the display panel.
- Solution: Check the fuses, relays, and wiring that control the lift and tilt functions. Replace any blown fuses and test the relays to ensure they are functioning correctly. Repair or replace any damaged wiring.
- Cause: The T200’s lift and tilt functions are controlled electronically by switches and relays. A failure in the electrical system, such as a blown fuse or malfunctioning relay, can prevent the hydraulic valves from being activated.
- Overloaded System
- Cause: Operating the Bobcat T200 beyond its rated capacity can overload the hydraulic system, causing pressure loss and failure of the lift and tilt functions.
- Symptoms: The machine may struggle to lift loads, and the tilt function may not operate as expected.
- Solution: Ensure that the load being lifted or tilted is within the machine’s rated capacity. If necessary, reduce the load and avoid overloading the machine to prevent damage to the hydraulic system.
- Cause: Operating the Bobcat T200 beyond its rated capacity can overload the hydraulic system, causing pressure loss and failure of the lift and tilt functions.
