The 2003 Volvo EC35 is a compact excavator that is widely used in construction, landscaping, and utility projects. Known for its durability, compact size, and maneuverability, this machine has made a name for itself in tight spaces where larger equipment would struggle to operate. However, like many pieces of heavy machinery, the EC35 can experience mechanical issues that affect its performance. One of the more common problems reported with this model is excessive vibration when the machine is moving, particularly when using the tracks. This issue can significantly affect the machine’s efficiency, and in some cases, may even pose safety risks to the operator.
In this article, we will explore the potential causes of heavy vibration in the Volvo EC35, focusing on track and roller issues, as well as the steps that can be taken to diagnose and address these problems.
The Volvo EC35: An Overview
Volvo Construction Equipment, a leading global manufacturer of construction machinery, has long been recognized for producing reliable and high-performing machines. The Volvo EC35 compact excavator, introduced in the early 2000s, became a popular choice for small-to-medium-scale jobs due to its powerful yet compact design. With a weight of approximately 3.5 tons, the EC35 offers a good balance between power and size, making it suitable for a wide range of applications, including digging, trenching, and lifting in confined spaces.
Powered by a reliable diesel engine, the EC35 features a fully hydraulic system for its boom, arm, and bucket, as well as a robust undercarriage that includes track rollers and a suspension system designed to provide stability and smooth movement. However, as with any machine, certain components of the EC35’s undercarriage and track system can experience wear and tear over time, leading to mechanical problems such as vibrations.
Understanding Track and Roller Issues in the Volvo EC35
The track and roller system on any tracked vehicle, such as the Volvo EC35, is critical for its mobility and stability. The tracks distribute the weight of the machine evenly over a larger surface area, which helps the machine move smoothly across rough and uneven terrain. Rollers, on the other hand, support the tracks and ensure smooth rotation while maintaining proper tension.
Several factors related to the tracks and rollers can contribute to excessive vibration when the machine is moving. Identifying these causes and addressing them is key to resolving the issue and preventing further damage.
1. Worn or Damaged Track Rollers
Track rollers are crucial components that support the weight of the machine and help guide the tracks along the ground. Over time, these rollers can wear out due to regular use, exposure to dirt and debris, or insufficient lubrication. If a roller becomes worn or damaged, it can cause the track to move unevenly, resulting in vibrations during operation.
Causes of Roller Issues:
To address worn or damaged track rollers, it’s essential to conduct regular inspections. Check for signs of wear such as cracks, dents, or visible damage. If a roller is showing significant wear, it should be replaced to prevent further damage to the track system and reduce vibrations. Regularly greasing the rollers during maintenance can also extend their lifespan.
2. Track Misalignment or Damage
Misaligned or damaged tracks can cause the machine to vibrate, especially when moving at higher speeds. Tracks can become misaligned due to improper installation, wear, or damage to the sprockets or rollers that guide the track. Additionally, if the track is damaged (e.g., a broken link or missing tread), it can cause uneven movement and significant vibrations.
Causes of Track Damage:
If track misalignment is suspected, it’s crucial to check the alignment and tension of the tracks. Use a track alignment tool to ensure that the tracks are centered properly and adjust the tension if necessary. If the track itself is damaged, replacing the damaged links or the entire track may be required. Clearing debris from the tracks regularly can help avoid obstruction and further damage.
3. Worn Track Shoes
The track shoes are the individual metal components that make up the track and come into direct contact with the ground. Over time, the track shoes can wear down, resulting in uneven track movement and vibrations. Worn track shoes reduce the contact area between the track and the ground, which can affect stability and cause shaking or vibrations while moving.
Causes of Worn Track Shoes:
Inspect the track shoes for excessive wear. If the track shoes are heavily worn, they should be replaced to restore proper contact and reduce vibration. Depending on the operating environment, using track shoes designed for specific terrains can help prevent premature wear.
4. Loose or Damaged Track Tensioners
Track tensioners are responsible for maintaining the correct tension on the tracks, ensuring that they remain taut during operation. If a tensioner is loose or damaged, it can cause the track to become too tight or too loose, leading to vibrations while moving. In some cases, a malfunctioning tensioner can also lead to premature wear of the track system.
Causes of Tensioner Issues:
Regularly check the tension of the tracks and adjust the tensioners as necessary. If the tensioner is damaged or malfunctioning, it may need to be repaired or replaced. Ensuring proper hydraulic pressure within the tensioner system is also essential for maintaining the correct track tension.
Preventative Measures to Minimize Track Vibrations
To prevent vibrations and extend the lifespan of the track and roller system, regular maintenance and proper operation are essential. Below are some key tips for maintaining the Volvo EC35’s tracks and rollers:
The Volvo EC35 is a reliable and powerful compact excavator, but like all heavy equipment, it is not immune to mechanical issues. Heavy vibration while moving, particularly when using the tracks, is a common issue that can often be traced back to problems with the track rollers, track alignment, or tensioning system. By conducting regular inspections, maintaining proper lubrication, and replacing worn components promptly, operators can minimize vibrations and ensure the continued performance of the machine.
Addressing these track-related issues not only improves comfort and efficiency but also prolongs the life of the Volvo EC35, ensuring it remains a valuable tool for any project.

If a tensioner is loose or damaged, it can cause the track to become too tight or too loose, leading to vibrations while moving. In some cases, a malfunctioning tensioner can also lead to premature wear of the track system.
Causes of Tensioner Issues:
- Hydraulic system failure
- Wear of the internal components of the tensioner
- Insufficient or excessive hydraulic pressure
Regularly check the tension of the tracks and adjust the tensioners as necessary. If the tensioner is damaged or malfunctioning, it may need to be repaired or replaced. Ensuring proper hydraulic pressure within the tensioner system is also essential for maintaining the correct track tension.
Preventative Measures to Minimize Track Vibrations
To prevent vibrations and extend the lifespan of the track and roller system, regular maintenance and proper operation are essential. Below are some key tips for maintaining the Volvo EC35’s tracks and rollers:
- Routine Inspections: Regularly inspect the tracks, rollers, and tensioners for signs of wear, misalignment, or damage. Early detection of issues can prevent more serious problems down the road.
- Proper Lubrication: Ensure that the rollers and other moving parts in the track system are adequately lubricated. Lack of lubrication can accelerate wear and increase the likelihood of vibration.
- Adjust Track Tension: Keep track tension within the recommended range to avoid excessive slack or tightness, both of which can contribute to vibrations.
- Clear Debris Regularly: Keep the tracks and undercarriage free from debris, dirt, and rocks, which can obstruct movement and cause damage to the tracks and rollers.
- Replace Worn Components Promptly: If any parts of the track system are worn or damaged, replace them promptly to prevent further issues and vibrations.
