The MF 70 backhoe loader, a versatile and reliable piece of equipment in the construction industry, is frequently used for digging, lifting, and material handling tasks. Known for its robust performance, the MF 70 has been a staple in many fleets. However, like any piece of machinery, it can encounter mechanical problems from time to time. One of the more common issues operators face with the MF 70 backhoe is a malfunction in the swing cylinder travel, which affects the machine's ability to rotate and position the boom effectively. This article delves into the potential causes of this issue, provides detailed troubleshooting steps, and outlines solutions to get your MF 70 backhoe working optimally again.
Understanding the Swing Cylinder System on the MF 70
The swing cylinder is a crucial component of the MF 70 backhoe, enabling the machine’s boom to rotate horizontally. This hydraulic system allows the operator to swing the boom from side to side, increasing the backhoe's versatility in tight spaces. The swing cylinder is powered by hydraulic fluid, and its proper functioning is essential for the smooth operation of the backhoe.
The MF 70 backhoe is typically equipped with two swing cylinders that work in tandem to provide the required motion. These cylinders are connected to the swing frame and are responsible for moving the boom in a controlled arc. They rely on hydraulic pressure to provide the necessary force to rotate the backhoe’s boom, making them vital to the machine's performance.
Causes of Swing Cylinder Travel Issues
Several factors can contribute to issues with the swing cylinder's travel on the MF 70 backhoe. These include hydraulic issues, mechanical failure, and wear and tear. Below are some of the common causes of swing cylinder problems:
1. Low Hydraulic Fluid Levels
One of the primary causes of poor swing cylinder performance is low hydraulic fluid levels. Hydraulic systems rely on sufficient fluid to generate pressure and provide the necessary force for movement. If the fluid is low, the swing cylinder may not operate smoothly, resulting in sluggish or uneven boom rotation.
2. Contaminated Hydraulic Fluid
Hydraulic fluid contamination is another common issue that can affect the swing cylinder’s performance. Contaminants such as dirt, debris, and water can compromise the fluid's ability to lubricate and provide consistent pressure to the hydraulic components. Over time, contaminated fluid can cause wear to the hydraulic seals, valves, and the swing cylinder itself, leading to reduced functionality or even failure.
3. Faulty Hydraulic Pump
The hydraulic pump is responsible for creating the pressure necessary to operate the swing cylinder. If the pump is faulty or not producing adequate pressure, the swing cylinder may not have enough power to rotate the boom effectively. A weak pump may result in slow or erratic movement of the backhoe's swing arm, making it difficult to position the boom accurately.
4. Leaking Hydraulic Hoses or Fittings
Another common issue is leaking hydraulic hoses or fittings. Hydraulic fluid leaks reduce the overall pressure in the system, preventing the swing cylinder from receiving the full force it requires. Leaks can occur at various points in the hydraulic lines, including the hoses, fittings, and connections, and they must be addressed promptly to restore proper functionality.
5. Damaged Swing Cylinder Seals
The seals inside the swing cylinder play a critical role in maintaining hydraulic pressure and preventing fluid leaks. If these seals become damaged or worn, they can allow fluid to escape, resulting in reduced pressure and poor swing cylinder performance. In some cases, this can also lead to hydraulic fluid contamination, exacerbating the issue.
6. Worn or Damaged Swing Cylinder Components
Over time, the internal components of the swing cylinder, such as the piston, rod, or bearings, can wear out. This wear can cause uneven movement, difficulty in fully extending or retracting the cylinder, and in some cases, total failure of the cylinder. Regular maintenance and inspections are necessary to catch these issues before they cause significant damage.
Troubleshooting the Swing Cylinder Travel Issue
If your MF 70 backhoe is experiencing issues with swing cylinder travel, it’s important to perform a thorough inspection to pinpoint the cause of the problem. Here’s how you can go about troubleshooting the issue:
1. Check the Hydraulic Fluid Levels
Start by checking the hydraulic fluid levels in the machine. If the fluid is low, top it up with the recommended fluid type. Ensure that the fluid is clean and free from contaminants. If the fluid appears dirty or discolored, it’s best to drain and replace it with fresh fluid.
2. Inspect the Hydraulic Fluid for Contamination
Examine the hydraulic fluid for any signs of contamination. If the fluid contains dirt, debris, or water, this can lead to issues with the swing cylinder. You can inspect the fluid by removing the fill plug and visually examining it, or by using a fluid test kit to detect the presence of contaminants.
3. Examine the Hydraulic Pump and Pressure
Check the hydraulic pump to ensure it is functioning correctly and generating the proper pressure. If the pump is malfunctioning, it may need to be repaired or replaced. A pressure gauge can help measure the output pressure of the hydraulic pump and determine whether it is within the specified range.
4. Inspect for Leaks in the Hydraulic System
Inspect the hydraulic hoses, fittings, and connections for any signs of leakage. Look for wet spots or drips around the hydraulic lines. Leaks can be difficult to spot, so it may be helpful to use a pressure test to identify the source of the leak. If you find any leaking hoses or fittings, replace or repair them as necessary.
5. Check the Swing Cylinder Seals
Inspect the seals inside the swing cylinder for any signs of wear, damage, or leakage. If the seals are compromised, they will need to be replaced. This may involve disassembling the swing cylinder, so it’s recommended to consult the manufacturer’s service manual or a qualified technician if you are unfamiliar with this process.
6. Examine the Swing Cylinder for Internal Damage
Finally, check the swing cylinder for any signs of internal damage, such as worn or damaged components. If the piston, rod, or other internal parts are worn out, the entire cylinder may need to be replaced. If the cylinder appears to be functioning improperly despite the external components being in good condition, internal damage may be the cause.
Solutions to Resolve the Swing Cylinder Travel Issue
Based on the findings from your troubleshooting, there are several possible solutions to fix the swing cylinder travel issue:

• Refill or replace hydraulic fluid: Ensure that the hydraulic fluid is at the correct level and is free from contaminants. Replace the fluid if necessary.

Engine RPM (revolutions per minute) plays a critical role in the performance, fuel efficiency, and hydraulic responsiveness of diesel-powered construction equipment. Whether you're operating a backhoe, loader, or excavator, fine-tuning the idle and high-speed RPM settings can improve machine behavior, reduce wear, and optimize productivity.
Why RPM Adjustment Matters
Diesel engines in heavy equipment are designed to operate within a specific RPM range to balance torque output, fuel consumption, and hydraulic flow. If the idle RPM is too low, the engine may stall under load or struggle to maintain hydraulic pressure. If it's too high, it can cause premature wear, excessive fuel use, and overheating.

• Low Idle RPM: Typically set between 800–950 RPM depending on engine model
  
• High Idle RPM: Often ranges from 1800–2200 RPM for full hydraulic performance
  
• Hydraulic Flow Dependency: Many machines use engine-driven pumps, so RPM directly affects hydraulic speed and power
  

• Mechanical Throttle: RPM is adjusted via a cable or rod connected to the governor lever on the fuel injection pump.
  
• Electronic Throttle: RPM is controlled by an electronic actuator receiving signals from the operator’s throttle lever or pedal.
  

1. Warm up the engine to operating temperature
   
2. Locate the governor housing on the injection pump
   
3. Identify the idle stop screw (usually spring-loaded and mounted externally)
   
4. Turn clockwise to increase RPM, counterclockwise to decrease
   
5. Use a tachometer to verify RPM accuracy
   
6. Adjust high idle screw if needed, typically located near the throttle linkage
   
7. Secure all locknuts and recheck throttle response
