The PC 150-5 is a highly regarded model in Komatsu's range of excavators, known for its robust performance and efficiency in a wide range of construction, mining, and excavation applications. Like any large machine, the PC 150-5 relies on several key mechanical components to function optimally. One of the most critical of these components is the slew bearing.
A slew bearing, also known as a turntable bearing or swing bearing, plays a vital role in enabling the excavator's upper structure to rotate (or "slew") independently of the undercarriage. The mechanics behind this process are complex, and a failure in the slew bearing can result in significant downtime and costly repairs. This article explores how the slew bearing works in the PC 150-5, common issues that can arise, and effective troubleshooting and maintenance strategies.
What is a Slew Bearing?
The slew bearing is a large, circular bearing that allows the upper structure (including the cabin, boom, and arm) of the PC 150-5 excavator to rotate over the undercarriage (or track assembly). It consists of an inner and outer ring, both with grooves or races for rolling elements (typically balls or rollers) that allow smooth rotation.
In simpler terms, it’s the component that allows the boom and bucket to swing in a 360-degree motion while the tracks remain stationary. This rotation is essential for digging, lifting, and loading tasks, which is why any malfunction or failure in the slew bearing can lead to a halt in operations.
How Does the Slew Bearing Work?
The slew bearing is powered by hydraulic motors that drive the rotation. The hydraulic motor’s torque is transferred through gears that mesh with the bearing's teeth, causing the outer ring to rotate with respect to the inner ring. The inner ring remains stationary, fixed to the upper structure, while the outer ring is mounted to the undercarriage.
When the hydraulic motor drives the slew bearing, it essentially acts as the point of articulation between the upper and lower portions of the excavator. This setup allows for smooth and continuous movement in the upper structure, facilitating the efficient operation of the excavator.

The Bobcat T300, like many skid steer loaders, features a “float” function that allows the machine’s arms to lift off the ground and float freely, following the contour of the surface. This function is essential for tasks like grading, leveling, or operating in uneven terrains. However, when this feature fails to work, it can significantly impact the machine’s performance, especially when precision is required for certain tasks.
In this article, we will explore the common reasons why the float function might stop working on a Bobcat T300, how to diagnose the issue, and the steps to fix it. By understanding these potential issues, you can save both time and money by addressing the problem early.
Understanding the Float Function
Before diving into troubleshooting, it’s helpful to understand what the float function does. The float function works by disengaging the hydraulic lift, allowing the loader arms to follow the contours of the ground. In normal operation, the loader arms are powered by the hydraulic system, but when the float function is activated, it allows the loader arms to move freely, following uneven ground without resistance from the hydraulic system. This is especially useful when grading or leveling soil, gravel, or other materials.
Common Causes of Float Function Malfunction
When the float function on the Bobcat T300 stops working, it can be due to several factors. Here are the most common causes:
1. Hydraulic System Issues
The most frequent cause of a malfunctioning float function is a problem with the hydraulic system. This can include:

• Low Hydraulic Fluid: If the hydraulic fluid level is low, the float function will not work properly. Always check the fluid levels and top them up if needed. Low fluid levels can occur due to leaks or regular wear and tear.
  
• Hydraulic Pump Failure: The pump is responsible for circulating fluid throughout the system. If the pump is faulty, the float function will fail. A pump failure may require professional repair or replacement.
  
• Contaminated Hydraulic Fluid: If the hydraulic fluid becomes contaminated with dirt or debris, it can cause the system to malfunction. Flushing the hydraulic system and replacing the fluid may resolve the issue.
  

• Clogged or Sticking Float Valve: The float valve may get clogged with debris, preventing it from functioning properly. This can lead to the float function not engaging. Cleaning or replacing the valve might be necessary.
  
• Damaged Float Valve: If the float valve is physically damaged or worn out, it may need to be replaced. Over time, constant pressure and use can degrade the valve’s performance.
  

• Faulty Switch: If the switch that activates the float function is faulty, it may prevent the system from engaging. This can be checked by testing the switch with a multimeter and replacing it if necessary.
  
• Electrical Wiring Issues: Sometimes the wiring leading to the float function control can become loose or damaged, resulting in a failure to activate the float function. Inspect the wiring for any visible damage or loose connections.
  

• Damaged or Sticking Control Lever: If the lever is physically damaged, the system may not respond as expected. Inspect the lever to ensure it is moving freely and not obstructed.
  
• Misalignment: Over time, the control lever can become misaligned, which could result in the float function not being properly engaged.
  

• Faulty Load Sensor: If the load sensor is not functioning properly, the machine may not be able to properly adjust the float function, causing issues when trying to operate it in float mode. Diagnosing and replacing a faulty load sensor may be necessary.
  

1. Check Hydraulic Fluid Levels:
   • Begin by checking the hydraulic fluid levels. Low fluid can cause a variety of hydraulic issues, including problems with the float function. If the fluid is low, top it up with the correct type of fluid. Make sure to check for any leaks in the system.
     
2. Inspect the Float Valve:
   • If the fluid levels are fine, check the float valve for blockages or damage. The valve should be free of debris and functioning smoothly. Clean or replace the valve if necessary.
     
3. Test the Control Switch:
   • Inspect the electrical control switch for proper operation. Use a multimeter to test the switch’s continuity. If the switch is faulty, replace it.
     
4. Inspect the Control Lever:
   • Check the control lever for any physical damage, misalignment, or obstruction. Ensure that the lever moves freely and engages the float function properly.
     
5. Check Electrical Wiring:
   • Inspect the wiring leading to the float system. Look for loose connections or damaged wires that may prevent the float function from engaging. Repair or replace damaged wiring as needed.
     
6. Check the Load Sensor:
   • If all else fails, inspect the load sensor. A faulty sensor may prevent the float function from working correctly. Consult a professional to diagnose and replace the sensor if necessary.
     

• Regularly Check Fluid Levels: Make it a habit to check your hydraulic fluid levels before each use to ensure optimal performance.
  
• Keep the Hydraulic System Clean: Periodically flush the hydraulic system and replace the fluid to keep it clean and free of contaminants.
  
• Inspect the Float Valve: Clean the float valve and check it regularly for signs of wear or damage.
  
• Check Electrical Components: Inspect switches, wiring, and connections to ensure proper operation.
