When it comes to maintaining tracked construction machinery like excavators and bulldozers, the undercarriage is one of the most expensive and essential components. A well-maintained undercarriage not only ensures smooth operations but also significantly reduces costly downtime and repairs. In this newsletter, we delve into critical issues, from track adjustment failures to choosing the right track shoes and measuring undercarriage wear.
The Hidden Costs of Incorrect Track Adjustment
Improperly adjusted tracks are a common issue in tracked excavators, track-loaders and bulldozers, often overlooked by operators. Tracks that are too tight accelerate wear on bushings, sprockets, idlers, and even the bearings in final drives. This can lead to premature failure of components, despite other parts, like rollers and track links, still being in good condition.
For excavators in the 15–30-ton range, track sag is critical and should generally be set between 3-5 inches (7-10 cm). A track chain that is too tight not only shortens component life but also risks cracking bushings. Too lose chains can to jump over the idler centre rim or the sprocket during drive operation. On uneven ground track rollers are no longer guiding the chain in line.
Tip: Always refer to your machine’s manual for specific guidelines or consult your local dealer for advice.
Corrosion and Seized Track Links: A Costly Problem
A significant issue seen in hydraulic excavators is the seizing of track links due to water—especially saltwater—penetration. Damaged seals allow water to corrode internal components, locking bushings and pins in place. Attempts to restore mobility with oil or grease are rarely successful, as the damage is inside the pins and bushings, not the visible chain links.
For minor issues, riding the machine on hard surfaces may restore some mobility. However, in severe cases, replacement of the chain is unavoidable.
Finding the Right Track Shoe Width: Striking the Balance
Choosing the correct track shoe width is a balancing act. Narrow track shoes provide sometimes better traction but may cause the machine to sink into soft ground. Narrower machines are easier to transport. On the other hand, extra-wide track shoes (LGP) distribute ground pressure more evenly but introduce increased torsion forces on drive components when operating on uneven terrain, leading to faster wear.
For every application, it’s essential to select the track shoe width that minimizes both wear and operational inefficiencies. Consult an expert or dealer to determine the best fit for your machine’s typical working environment.
Precision Measurement: Know Your Undercarriage’s Remaining Life
The undercarriage accounts for a substantial portion of a machine’s value—take the Caterpillar D8T, for example, where the undercarriage value can reach €25,000. Misjudging the remaining life by even 30% can result in a financial loss of €7,500.
Proper measurement ensures accuracy. MEVAS-trained inspectors recommend using tools like:
Track Gauges: To ensure the correct track spacing.
Track Roller Callipers: To assess roller diameter and wear.
Shoe Height Gauges: To check track shoe condition. By using these tools, operators can determine wear levels and predict replacement timelines accurately.
Avoiding Roller Sequence Errors
In Caterpillar or Komatsu XL bulldozers, proper track roller sequencing is crucial. These machines typically use a mix of single and double flange rollers, but inexperienced fitters sometimes install rollers in the wrong sequence—or worse, entirely single-flange rollers. Such errors can compromise performance and accelerate wear. Always cross-check roller configurations with manufacturer specifications.
Key Inspection Points for Used Machines
When inspecting a used bulldozer or excavator, pay special attention to:
Equalizer Bar and Bearings: This component connects undercarriage frames and facilitates horizontal movement. Any excessive play in joints and pivots can indicate expensive repairs ahead.
Thorough inspections can save thousands in repair costs. If you’re unsure about measurements or need a detailed guide, MEVAS offers step-by-step instructions and video tutorials.
Maintaining Undercarriage Health: Best Practices
Monitor Track Tension Regularly: Adjust sag based on manufacturer recommendations.
Choose Track Shoes Wisely: Match the width to the terrain for optimal performance.
Schedule Regular Measurements: Use proper tools to assess wear and address issues proactively.

When purchasing used construction equipment, especially machinery with multiple previous owners, accurately determining its operating hours can be challenging. Over time, machines may undergo component replacements, have their hour meters swapped out, or even be assembled from parts of other machines. The main components, such as engines, hydraulic pumps, and transmissions, typically have a lifespan of 10,000 to 20,000 operating hours, and replacing them can be costly. Knowing how many hours each component has operated is essential.
Unfortunately, some machines may have had their hour meters replaced or even manipulated to show fewer hours than they’ve actually been used. This can mislead buyers and inflate the machine’s market value. So, how can you ensure that a machine’s recorded hours are accurate?
Verifying Operating Hours: What Are Your Options?
There are several ways to uncover a construction machine’s true history:
Consult Authorized Dealers: The simplest method is to contact an authorized dealer for the machine’s brand. Many manufacturers maintain detailed service records, often accessible through dealer databases. For example, Komatsu stores this data through the Komtrax system.
Access Product Status Reports: Some brands, like Caterpillar and Volvo-CE, offer downloadable product status reports, known as PSR or MATRIS reports. These reports provide insights into fuel consumption, historical temperature and pressure data, and other valuable metrics. Key operational events are time-stamped with specific operating hours, allowing you to verify if the displayed hours align with the machine’s actual usage. For Caterpillar, these reports can even include serial numbers for original components like the engine and transmission.
Send an Inspection Service to Check the Equipment: An experienced technician can perform a thorough inspection to determine the actual condition of the machine. They can determine whether the condition of the drives, the engine exhaust and the machine’s performance match the operating hours.
Who Can Help with This Verification?
If the machine remains in the same country where it was recently used, obtaining data from the local dealer is usually possible, although dealer cooperation can vary. If a dealer is uncooperative, you may need to get creative in finding alternative sources of information.
For larger machines, like quarry dump trucks or open-pit mining excavators, previous users often maintain component history logs. These documents record when major parts, such as engines, gearboxes, or axles, were replaced or overhauled, which can further verify the machine’s operational history.
What measures can you take yourself?
Before you buy a machine or hire an external inspector to carry out the inspection, it is advisable to clarify a few things yourself. Ask the seller for documents that prove the machine’s service history. Ask for pictures of the machine’s and engine’s serial number plates. Consider whether the stated operating hours match the machine’s age. Use Google to see if the machine’s serial number is known, e.g. from an auction. Be especially careful if the deal looks too good.
How MEVAS Can Assist in Verifying Operating Hours
When you choose MEVAS to inspect a used construction machine, you benefit from our industry connections and specialized knowledge. Our inspectors are equipped with diagnostic tools for Caterpillar machines and some Volvo CE models. In cases where we don’t have direct access to a brand’s diagnostic tools, we can reach out to local dealers on your behalf to inquire about available data.
With a MEVAS inspection, you’ll receive an assessment of whether the condition of key components aligns with the machine’s displayed operating hours. As independent inspectors since 2006, we bring both expertise and integrity to every inspection. We can also guide you toward trusted dealers with reputable equipment or, conversely, advise caution when a machine supplier requires extra scrutiny.

Repainted and Incorrectly Labeled Machines
We often inspect machines in China for our customers. We have found many copied or mislabeled machines. For example, we found a CAT 966H wheel loader that was not a real Caterpillar. It had a Cummins engine and an old air brake system. Sometimes, smaller excavators are labeled as larger models, like a Volvo EC290 labeled as a Volvo EC360.
Recommended Machinery Portals
We do not recommend a specific portal. However, it is safest to use websites where the seller’s identity and location have been verified. However, a selection of portals is visible at www.used-equipment.de
Dangerous Places to Buy From
Creating a website and selling construction machinery can be easy and cheap. Some people create fake websites, copy photos from other sites, and offer machines at very low prices. They might ask for a deposit to reserve the machine. Be very careful if a deposit is required before you see the machine.
What to Check When Buying a Used Machine
If you do not know the seller or have not received a recommendation, always send someone to see the machine. Using a professional inspection service like Mevas is a good idea. They will confirm if the machine exists and provide a detailed inspection report with photos and videos. Ask the supplier for maintenance records of the machinery. These records can provide insights into how well the machine has been cared for and if it has had any major repairs.
What to Pay Attention to When Paying
Check the seller’s account number. It should be in the same country as the seller. Call the seller’s accounting department to verify the number. Avoid paying via Western Union or with cryptocurrencies. It is better to spend an hour checking the website and the offer than to lose $10,000.
Secure Transportation and Machine Certification
Ensure that the machinery is transported securely. Hire reputable logistics companies that specialize in transporting heavy equipment to avoid any damage during transit. If you are importing machinery, be aware of the import regulations in your country. This includes understanding any duties, taxes, or restrictions that may apply. In some countries it is required to have a CE certification or to comply with emission regulations.

What means Heavy Equipment Procurement?
Heavy equipment procurement is the process of acquiring the large machinery needed for industries like construction, mining, agriculture, and forestry. This involves identifying the specific equipment requirements, finding qualified suppliers, negotiating the best price and terms, and finally finalizing the purchase.
Here’s a breakdown of the typical heavy equipment procurement process:
Identifying Needs: The first step involves understanding what kind of equipment is needed. This considers factors like project requirements, budget, and existing equipment inventory.
Supplier Research: Once the needs are identified, potential suppliers who can provide the required equipment are researched. This may involve contacting manufacturers, distributors, or even used equipment sellers.
Qualification and Selection: Suppliers are then evaluated based on factors like experience, reputation, pricing, and after-sales support. A shortlist of qualified suppliers is created for further negotiation.
Negotiation and Contract: Negotiations with shortlisted suppliers are conducted to get the best possible price, financing terms, and delivery schedules. Once an agreement is reached, a formal contract is signed.
Obtaining heavy equipment can be a significant investment, so the procurement process aims to ensure efficient use of funds and the acquisition of equipment that meets the project’s needs.
