The Role of Blade Stability in Dozer Performance
A dozer’s blade is its defining feature—responsible for pushing, grading, and shaping terrain. Whether it’s a straight blade (S-blade), universal blade (U-blade), or semi-U hybrid, the blade must maintain tight mechanical control to deliver precise cuts and efficient material movement. Excessive play or “slop” in the blade undermines grading accuracy, increases wear on hydraulic components, and can lead to operator fatigue due to constant correction.
Blade movement is controlled by a combination of hydraulic cylinders, pivot pins, bushings, and structural bosses. Over time, these components wear due to vibration, impact, and abrasive material exposure. When the blade begins to rock or shift during operation, the root cause is often mechanical—not hydraulic.
Common Causes of Blade Looseness
Sloppy blade behavior typically results from:

• Worn pivot pins at the blade trunnions
  
• Elongated holes in the blade boss or push arms
  
• Cracked welds or fatigued gussets
  
• Missing or undersized shims
  
• Excessive clearance between bushings and pins
  
• Improper lubrication or dry joints
  

• Measure lateral and vertical movement at full extension and retraction
  
• Use calipers to check pin diameter and boss hole roundness
  
• Inspect welds around the push arm and blade mount for cracks
  
• Check for missing shims or spacers
  
• Evaluate bushing wear with feeler gauges
  

• Pin-to-bushing clearance should be under 0.010" for tight control
  
• Boss hole roundness should not deviate more than 0.015"
  
• Lateral blade movement should be under 0.5" under load
  

• Replace worn pins with OEM or custom-machined units
  
• Weld and re-bore boss holes to restore roundness
  
• Install new bushings with press-fit tolerances

Excavators are crucial machines in the construction, demolition, and mining industries. Their ability to rotate or “slew” helps them perform a variety of tasks, from digging trenches to loading materials. However, like any complex machine, excavators can experience performance issues. One common issue operators may face is a failure of the slew function at low engine revolutions per minute (RPM). This can manifest as an inability to rotate the boom or the machine seeming to catch or jerk when trying to slew at low RPMs. In this article, we will explore the causes of such issues, potential solutions, and best practices for maintaining excavator slew systems.
Understanding Excavator Slew Systems
An excavator’s slew system consists of several key components that allow the machine’s upper structure (the cab, boom, and arm) to rotate around the undercarriage. The slew motor, hydraulic system, slew ring, and control valves work together to enable the rotation of the excavator. These systems are powered by hydraulic fluid, which is pressurized by the hydraulic pump and controlled through various valves.
When you face an issue where the slew mechanism fails or hesitates at low RPM, it is important to understand the mechanics behind how the hydraulic system works. The hydraulic system relies on engine power to generate sufficient flow to operate various functions, including the slew motor. At low RPMs, the engine may not produce enough hydraulic flow or pressure to operate the slew motor efficiently, which can lead to poor performance or failure to rotate.
Common Causes of Slew Problems at Low RPM
Several factors can contribute to problems with an excavator’s slew system, particularly when operating at low engine RPMs. Some of the most common causes include:
1. Low Hydraulic Pressure or Flow
One of the primary reasons for an excavator’s slew function to fail at low RPM is insufficient hydraulic pressure or flow. Hydraulic systems are dependent on the engine to drive the pump, which then pressurizes the hydraulic fluid to perform tasks such as lifting, digging, and slewing. When the engine runs at a low RPM, the pump may not generate enough flow to drive the slew motor, especially if the pump is worn out or has been poorly maintained.
Solution: Check the hydraulic fluid levels and ensure that the hydraulic filter is clean. Low fluid levels or dirty filters can reduce pressure. Additionally, inspect the hydraulic pump and motor to ensure they are in good working condition and that no air is trapped in the system.
2. Faulty Slew Motor or Components
The slew motor is the component that directly powers the rotation of the upper structure of the excavator. If the motor is malfunctioning, it may cause sluggish or incomplete slew motion, particularly at lower RPMs. Internal damage or excessive wear in the slew motor’s components, such as gears or seals, can restrict the motor’s ability to rotate the machine’s upper structure.
Solution: Perform a visual inspection of the slew motor and its components. If the motor is damaged, it may need to be repaired or replaced. Additionally, check for signs of leaks around the motor, which could indicate damaged seals.
3. Hydraulic Control Valve Malfunctions
The hydraulic control valve is responsible for directing hydraulic fluid to various parts of the system, including the slew motor. If there is an issue with the valve, such as dirt or debris blocking it, or if the valve is faulty, it may prevent the proper amount of hydraulic fluid from reaching the slew motor.
Solution: Inspect the hydraulic control valve for damage or blockage. Cleaning or replacing the valve may resolve the issue. Additionally, ensure that the valve is properly adjusted to allow the correct flow of hydraulic fluid.
4. Low Engine RPM or Insufficient Power
In some cases, the issue may not be directly related to the hydraulic system but rather to the engine's performance. If the engine is not running at the correct RPM, it may not be able to provide the necessary power to drive the hydraulic pump efficiently. This can cause issues with several functions, including the slew.
Solution: Verify the engine is operating within the manufacturer’s recommended RPM range. If the engine is struggling to reach sufficient RPMs, it could be a sign of an underlying issue such as a fuel delivery problem, a clogged air filter, or poor engine maintenance. A thorough inspection of the engine and its components is recommended.
5. Worn or Damaged Slew Ring
The slew ring, also known as a swing bearing, supports the upper structure and allows it to rotate on the undercarriage. If the slew ring becomes worn or damaged, it may cause the upper structure to rotate unevenly or fail to rotate smoothly. This can result in the machine seeming to “catch” or hesitate during rotation.
Solution: Inspect the slew ring for signs of wear, damage, or contamination. If the bearing shows signs of wear, it may need to be replaced. Ensure that it is properly lubricated to reduce friction and wear.
Steps for Troubleshooting and Fixing Slew Issues
If your excavator is experiencing slew issues, here are the steps you should take to diagnose and address the problem:
1. Inspect Hydraulic Fluid and Filters
Start by checking the hydraulic fluid level and quality. If the fluid is low, top it off with the appropriate type of hydraulic oil. Also, inspect the filters for blockages or contamination. Dirty or clogged filters can prevent proper fluid flow to the slew motor.
2. Check the Hydraulic Pump and Motor
Next, inspect the hydraulic pump and motor for any signs of damage or excessive wear. If the pump is underperforming, it may need to be rebuilt or replaced. Similarly, check the slew motor for signs of leakage, wear, or internal damage.
3. Test the Hydraulic Control Valve
Inspect the hydraulic control valve to ensure it is functioning correctly. Look for any visible blockages, leaks, or signs of wear. In some cases, flushing the valve or cleaning its components may be sufficient to restore proper function.
4. Verify Engine Performance
Ensure that the engine is operating at the correct RPM. Low engine power or issues with the fuel system can affect the hydraulic pump's performance. Perform a diagnostic check to identify any engine-related issues and address them promptly.
5. Examine the Slew Ring
Finally, inspect the slew ring for damage or wear. If the slew ring is excessively worn, it may be causing the hesitation or uneven rotation. Lubricate the slew ring regularly to reduce friction and prevent unnecessary wear. If the damage is severe, consider replacing the slew ring.
Prevention and Best Practices
To avoid future slew-related issues, follow these best practices for maintenance and operation:

• Regular Maintenance: Perform routine inspections and maintenance on the hydraulic system, including checking fluid levels, filters, and seals.
  
• Lubrication: Regularly lubricate the slew ring and other rotating components to reduce wear and friction.
  
• Monitor Engine Performance: Ensure that the engine is running at the correct RPM, and address any issues with power delivery promptly.
  
• Avoid Overloading: Avoid overloading the machine, as excessive stress on the slew motor and hydraulic system can lead to premature failure.

• Volvo G990C: The G990C is known for its comfort and advanced technology. While it’s a top-tier machine, the C110 offers a more cost-effective solution with comparable performance in terms of grading and efficiency. Volvo’s model, however, is more geared toward larger projects and larger fleets.
  
• John Deere 670GP: John Deere is another strong contender in the road grader market. The 670GP provides similar features to the Champion C110 but often comes with a more premium price tag. For those looking for an entry-level grader with strong features, the C110 offers great value without compromising on performance.
