The Deere 710D backhoe is a powerful and versatile machine used in construction, agricultural, and utility applications. One of the critical features of the 710D is its Extendahoe system, which allows the backhoe’s digging arm to extend for deeper reach and enhanced digging capabilities. However, over time, components in the Extendahoe system may experience wear, particularly the shims that provide necessary clearance and help the system operate smoothly.
In this detailed guide, we’ll explore how to replace the Extendahoe shims on the Deere 710D, the importance of proper shim replacement, and common issues that can arise when shims are worn or incorrectly installed. We’ll also cover essential terms and best practices to ensure your machine remains in peak condition.
What is the Extendahoe System?
The Extendahoe is an extendable arm system designed to increase the reach of the backhoe. This feature is particularly useful when the operator needs to reach further without moving the machine or adjusting its position. The Extendahoe system typically consists of an extendable boom arm that can slide out and lock in place to provide additional digging depth.
The system is operated hydraulically, with cylinders that control the extension and retraction of the boom. The shims within this system play a crucial role in maintaining the proper alignment and clearance between moving parts, ensuring smooth operation and preventing excessive wear.
Importance of Shims in the Extendahoe System
Shims are small, precision-made pieces of metal that provide the necessary clearance between two moving parts. In the case of the Deere 710D Extendahoe, shims are used in several places to ensure that the extendable boom and other hydraulic components move smoothly without binding or excessive friction.
As the backhoe operates, the shims gradually wear down due to the constant movement and pressure. If these shims wear out too much or become damaged, it can cause issues such as:

As the backhoe operates, the shims gradually wear down due to the constant movement and pressure. If these shims wear out too much or become damaged, it can cause issues such as:
- Excessive play in the Extendahoe arm, leading to reduced precision and control.
- Hydraulic system inefficiency, as worn shims can cause improper alignment, reducing the effectiveness of the hydraulic cylinders.
- Premature wear of other components, such as the cylinders and bushings, due to increased friction or misalignment.
Symptoms of Worn Extendahoe Shims
Before diving into the replacement process, it's essential to identify when the shims in your Deere 710D Extendahoe need replacing. Some common signs of worn or damaged shims include:
- Excessive Movement or Slack:
- If the Extendahoe arm has excessive movement or slack, this may indicate that the shims have worn down. The arm might wobble or feel less stable during operation, which can lead to decreased precision when digging or reaching.

- Uneven or Jerky Extension/Retraction:
- When the backhoe's arm extends or retracts unevenly or jerkily, it can signal that the shims are no longer providing smooth guidance. The system may struggle to operate, requiring more force to move the arm, and could cause uneven wear on other parts.

Replacing the shims in the Extendahoe system of the Deere 710D requires careful attention to detail and some mechanical expertise. Here is a step-by-step guide to help you replace the shims properly:
1. Preparation and Safety
Before beginning any repair work on your Deere 710D backhoe, make sure to follow proper safety protocols:
- Turn off the engine and ensure the machine is on a flat, stable surface.
- Engage the parking brake and use wheel chocks to prevent the machine from moving during the repair.
- Wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and steel-toed boots.
To replace the shims, you will need to access the Extendahoe’s sliding components. This may involve:
- Raising the backhoe arm: Extend the arm to its maximum length to gain access to the areas where the shims are located.
- Support the boom: Use a jack or other suitable support to ensure that the arm is stable while you work on the shims.
- Remove any covers or panels: Depending on the design of the Extendahoe, you may need to remove covers or panels to expose the shims and the internal components.
Once you have access to the shims, carefully inspect them for signs of wear, cracking, or damage. If the shims appear to be worn down or are causing issues, it’s time to replace them.
- Use a wrench or appropriate tools to remove any bolts or fasteners holding the shims in place. Be mindful of the surrounding components and ensure that you don’t cause any damage while removing the shims.
- If the shims are stuck or difficult to remove, use a soft mallet to gently tap them loose.
Before installing new shims, thoroughly clean the areas where the shims sit. Removing any dirt, debris, or old grease is essential to ensure that the new shims fit correctly and work efficiently. Use a brush and rag to clean the shim surfaces, and apply a light coat of lubricating grease to the surfaces where the shims will sit.
5. Install New Shims
- Install the new shims in the same position as the old ones. Be sure to align the new shims carefully and ensure they fit snugly in place.
- Secure the shims by reattaching the bolts or fasteners that were previously removed. Tighten them according to the manufacturer’s torque specifications to avoid any loose components.
Once the new shims are in place, reassemble any panels or covers that were removed. Ensure that all fasteners are properly tightened and that everything is secure.
- Test the Extendahoe system by extending and retracting the arm several times. The movement should be smooth, and the arm should operate with the correct precision.
- Check for any signs of friction, excessive noise, or other issues that may indicate the new shims are not functioning as intended.
While replacing the shims is generally straightforward, there are some common issues that may arise:
- Misalignment: If the new shims are not properly aligned, the system may not work correctly. Always double-check the alignment before securing the new shims.
- Incorrect Shim Size: Ensure that the new shims match the manufacturer’s specifications in terms of size and material. Using the wrong size can lead to poor performance or damage to the Extendahoe system.
- Damaged Hydraulic Components: If the Extendahoe system continues to have issues after shim replacement, the problem may lie elsewhere in the hydraulic system. Check the hydraulic fluid, filters, and cylinders for damage or leaks.
To extend the life of your Deere 710D Extendahoe and reduce the need for frequent shim replacements, follow these maintenance practices:
- Regular Inspections:
- Periodically inspect the Extendahoe system, paying close attention to the shims, hydraulic lines, and seals. Look for signs of wear or damage early to prevent more severe issues.
