In many cases, asset managers in mining companies find themselves urgently needing spare parts for haul trucks or other mobile equipment. Factors such as cost and convenience often make alternative parts an appealing option.
In an interview with Machinery Maintenance Matters, Marnix Reedijk, Service Market Manager for Africa at Volvo Construction Equipment (VCE), explains the risks of uninformed spare parts procurement to equipment reliability, as well as the often overlooked legal implications in mining operations.

MMM: We have encountered claims in some spare parts vendors’ marketing materials, such as “as good as OEM parts, or even better”. What are the potential flaws or limitations in such assertions
Marnix: We often see these kinds of claims, and while they may sound convincing, they are rarely backed by the same level of engineering, testing, and accountability that goes into genuine OEM parts. At Volvo CE, every part is developed in tandem with the machine itself, using original specifications, premium materials, and stringent validation under a range of operating conditions.
Unfortunately, so-called “equivalent” parts may look similar, but they often fall short in terms of precision, durability, or safety, especially in tough African environments where equipment is pushed to the limit.
It is important to remember that marketing claims are not the same as demonstrated performance backed by data and warranty.
MMM: What are the key differences between OEM parts and manufactured replacement parts?
Marnix: The biggest differences come down to engineering standards, materials, testing, and long-term support. OEM parts, like those from Volvo CE, are built using original designs and go through rigorous quality assurance processes. We know exactly how each component interacts with the machine as a whole. This is something third-party manufacturers simply cannot replicate.
Many replacement parts are built to fit but not necessarily to last. The tolerances may be slightly off, the materials may not withstand high heat or pressure, and the impact on other systems within the machine is often unpredictable. With OEM parts, there is full traceability and support. This makes a major difference in overall cost of ownership.
MMM: Fleet managers sometimes state that they urgently require a part to avoid costly downtime and therefore opt for replacement parts. What is your view on this approach?
Marnix: I completely understand the urgency that fleet managers face. Downtime is costly, especially in mining and construction where project timelines are tight. However, using non-genuine parts as a quick fix often leads to more serious issues later, including unscheduled repairs, system failures, and even safety incidents.
In the long run, this reactive approach usually ends up costing more in repairs and lost productivity. Our Volvo dealer network across Africa is trained to respond quickly and help reduce lead times so customers can keep operations running without compromising on quality.
MMM: Many believe they are reducing costs by choosing third-party parts. What is your perspective on this?
Marnix: It is an understandable mindset, especially when budgets are tight. But the reality is that non-genuine parts often result in hidden costs, such as reduced component life, increased fuel consumption, greater wear on related systems, and more frequent breakdowns.
Over time, those costs add up. Our customers across Africa who invest in genuine Volvo parts consistently report better uptime, lower fuel use, and longer service intervals. While a third-party part may save money today, the true long-term cost is almost always higher.
MMM: What risks are associated with using unvetted third-party replacement parts in your equipment?
Marnix: The risks are significant. They include machine failure, increased safety hazards, reduced efficiency, and environmental issues such as fuel leaks or emissions irregularities. For example, a poor-quality hydraulic seal could lead to fluid loss, overheating, and severe damage to the entire hydraulic system.
In mining operations or remote construction sites, the consequences can be serious. These risks affect not only cost but also operator safety and project timelines.
MMM: Does VCE permit the use of third-party replacement parts? If so, under what specific terms and conditions?
Marnix: Volvo CE does not prohibit customers from using third-party parts. We understand that circumstances vary.
However, we always advise caution. If a third-party part is installed and causes damage to other components, any resulting failure may not be covered under the Volvo warranty.
Our advice is to always consult your authorised Volvo dealer before installing any non-genuine component. They can help assess the risk and recommend the best option.
MMM: Can the use of third-party replacement parts potentially void the OEM warranty if those parts cause equipment damage?
Marnix: Yes, it can. If a non-genuine part causes a machine failure or damages other systems, Volvo CE cannot guarantee support under the standard warranty.
That is why we urge our customers across Africa to protect their investment by using parts that are designed, tested, and guaranteed to work seamlessly with Volvo equipment. It is about safeguarding uptime and long-term reliability.
MMM: Are there any specific considerations or best practices you would recommend for industries in Africa regarding the procurement and installation of spare parts?
Marnix: Yes. I would recommend three key best practices. First, work with authorised Volvo dealers who can provide genuine parts, expert advice, and warranty support. They understand local operating conditions and can help plan preventive maintenance schedules.
Second, avoid stockpiling unverified parts, especially for critical systems such as hydraulics, electronics, or filters. The wrong part can compromise the entire machine. Third, invest in parts planning. We support customers with tailored service agreements and forecasting tools that help manage inventory, avoid stockouts, and reduce downtime.
Africa’s conditions are often extreme, so using the right parts is not just about cost. It is also about performance, safety, and sustainability.
MMM: What is the latest information you can share with our readers about VCE spare parts, particularly any innovations in enhancing wear protection to ensure high equipment availability?
Marnix: We are constantly developing smarter solutions to help our machines last longer and perform better. One recent innovation is the Volvo Tooth System, which features enhanced wear material and an easy change-out design for extreme applications such as mining and quarrying.
We have also improved our filter technology, which allows longer service intervals while maintaining maximum protection. This is essential in dusty or high-humidity African environments.
Additionally, our ActiveCare support packages allow us to monitor component wear remotely using CareTrack telematics. This enables us to recommend part replacements before failure occurs, reducing unplanned downtime. It is all part of our commitment to smart, dependable uptime support tailored for the challenges of African industries.
