Removing an excavator track is a demanding but manageable task when approached with planning, the right tools, and a strong focus on safety. Done correctly, it protects both the operator and the machine, while setting the stage for installing quality replacement undercarriage parts that keep equipment productive in Canadian conditions.
How Should You Prepare the Excavator Before Track Removal?
Proper preparation stabilizes the machine, protects personnel, and reduces the risk of sudden movement or tipping during the job. It sets a controlled environment where you can work on heavy components and stored energy systems with much lower risk.
Begin by parking the excavator on firm, level ground that can safely support the machine, jacks, and cribbing over time, not just for a few minutes. Engage the parking brake, lower the blade and boom fully to the ground, and shut off the engine. Remove unnecessary personnel from the work area and establish clear communication with anyone assisting. Use appropriate PPE—gloves, safety boots, eye protection—and ensure the hydraulic system is depressurized and the key is removed so the machine cannot be started accidentally. On larger or busier sites, treating the machine as “locked out” with clear signage and procedures provides an extra layer of protection.
What Tools Are Required to Remove an Excavator Track?
Having the right tools ready before you start prevents improvisation and unsafe shortcuts once the track is loose. The exact setup may vary with machine size, but a few core tools are common across most excavators.
Typically, you will need a grease gun and suitable wrench to work with the track tensioner, along with a pry bar to help move the track off the sprocket and idler. Wooden blocks or stands are important for supporting both the machine and the removed track, helping to avoid damage or instability. For some track systems, especially those with a master pin, a hydraulic pin press or, in some cases, a hammer and drift pins can be used for pin removal. Larger excavators often require lifting equipment such as chain hoists, slings, or forklifts to handle the weight of the track safely and prevent strain injuries.
How Do You Release Track Tension on an Excavator?
Safely releasing track tension is a critical step because the system stores energy that can cause sudden movement or component failure if handled carelessly. The goal is to retract the idler so the track loosens enough to be guided off the undercarriage.
Locate the grease valve on the track tensioner assembly and use the appropriate wrench to carefully loosen or remove it. Then, use a grease gun or other approved method to release or pump grease out of the adjuster, allowing the idler to move back and the track to slacken. This process must be done slowly and deliberately to avoid rapid changes in tension. Keep hands and body clear of the moving idler and track during this step, and monitor the track as it loosens to ensure it does not drop or shift unexpectedly.
How Is the Track Physically Removed From the Machine?
Once tension is released and the track is sufficiently slack, the focus shifts to controlled, mechanical removal. This stage combines leverage, support, and sometimes lifting to ensure the track comes off without damaging components or injuring personnel.
Start by using a pry bar to lift the track off the sprocket teeth, working methodically along the circumference rather than forcing a large section at once. With the track off the sprocket, you can gradually push or pull it off the front idler or guide it away from the undercarriage. Due to the weight of the assembly, this often requires two people on smaller machines and proper lifting gear on larger ones. Support the track with wooden blocks as it comes free, and always keep hands and feet clear of pinch points between the track, sprocket, rollers, and ground. Avoid using the machine’s own power to “walk” the track off in an uncontrolled way.
What Safety Precautions Are Especially Important During Track Removal?
Track removal combines multiple hazards: stored hydraulic energy, heavy components, awkward body positions, and limited visibility. A systematic safety mindset is essential to prevent serious injuries arising from what might seem like a routine task.
Before starting, confirm the machine is stable, the ground is level and firm, and all lifting and support equipment is correctly rated for the loads involved. Wear PPE, use clear verbal signals or hand signals with helpers, and ensure only essential personnel are in the work zone. Never position any part of your body between the track and the undercarriage or under a suspended load. Avoid rushing, even under time pressure, and stop the job if the machine shifts, tools are inadequate, or conditions change. After removal and reassembly, conduct a careful test run at low speed to check tension, alignment, and smooth operation before returning the excavator to normal work.
Why Are Quality Replacement Undercarriage Parts Important?
Once a track has been removed, the choice of replacement components directly affects machine life, reliability, and operating cost. The undercarriage carries a large share of an excavator’s total maintenance budget, so quality has real financial impact over time.
Using durable tracks, rollers, idlers, and sprockets helps reduce premature wear, minimizes the risk of unexpected breakdowns, and keeps the machine working reliably in demanding environments, including Canada’s varying climate and ground conditions. While very low-cost parts may look attractive, they often shorten service intervals and increase downtime, raising total cost of ownership. Industry suppliers like AFT Parts focus on undercarriage components engineered to fit major excavator brands, providing a more predictable service life and performance profile. Choosing well-matched parts also supports smoother operation, reduced vibration, and less stress on related components like final drives.
Which Online Options Exist for Buying Undercarriage Parts in Canada?
For Canadian operators and contractors, access to reliable parts sources is essential to keep fleets running and avoid extended downtime. Online channels have become an important complement to traditional local dealers.
Reputable online stores allow customers to buy undercarriage components compatible with popular excavator brands, often with clear product data to support correct selection. Many Canadian-focused platforms offer competitive deals and occasional options for the best price on high-use items like tracks and rollers. Some suppliers provide free shipping above a certain order value, which can be especially helpful for remote or regional operations. Within this market, AFT Parts is one example of a specialist undercarriage supplier that serves Canada through an online model, giving equipment owners another avenue to shop for critical components when time and availability matter.
How Should Removed Excavator Tracks Be Handled and Stored?
What happens to the track after removal affects both safety on site and the potential for reuse or inspection. Proper handling prevents new damage and keeps the work area orderly and safer for everyone involved.
Once the track is off the machine, set it down on stable wooden blocks rather than directly on the ground or on brittle supports like concrete blocks. This helps avoid deformation and reduces the risk of sudden collapse. Clean the track as needed and inspect it for wear, cracks, cuts, or damaged links and guide surfaces. If it will be stored for future use, choose a dry, sheltered location to limit rust and corrosion. Good housekeeping around stored tracks also reduces trip hazards and makes it easier to manage inventory and plan maintenance.
What Other Important Considerations Are Often Overlooked?
Beyond the basic steps of loosening tension and sliding off the track, there are additional factors that significantly influence safety, warranty, and long-term machine performance. These points are often missed but are critical from a professional maintenance standpoint.
Always consult the excavator’s operator and service manuals before starting, as different models use different undercarriage designs, master pin arrangements, and jacking points. Incorrect methods can cause structural damage or affect warranty coverage. Take site conditions seriously—mud, ice, and loose aggregate can undermine jacks and stands, requiring extra cribbing or relocation to a prepared pad. Give attention to ergonomics by using lifting aids rather than relying solely on manual strength. Finally, ensure that the people performing the work are properly trained and understand the hazards, not just following a guide for the first time. After reassembly, perform a systematic inspection and low-speed test to confirm correct track tension, alignment, and absence of leaks or abnormal noises before committing the machine back to full-duty operation.
