Who Actually Builds the Engine? Komatsu, New Holland, and Hyundai Excavators Compared

Pop the hood, or the engine access panel, on a Komatsu, a New Holland, and a Hyundai excavator, and you'll find three genuinely different answers to the same question: who actually builds the engine running your machine? It's not a question most contractors ask before buying, but it shapes parts availability, warranty service, and long-term maintenance costs in ways that are worth understanding before you sign a financing agreement. Here's what's actually under the hood of each of these three approved manufacturers' excavator lineups, based on their own published specifications, and why the answer matters more over a five-year ownership period than it does on delivery day.

Komatsu: Fully In-House, Top to Bottom

Komatsu builds its own diesel engines in-house across its excavator lineup, including the SAA6D107E-3 that powers mid-size machines in the PC220LC-12's weight class. This is a genuinely different model than most of the industry: Komatsu designs, engineers, and manufactures the engine block itself, rather than sourcing it from an outside diesel supplier and integrating it into the machine. The practical upside for a contractor is a single point of accountability. When something goes wrong with a Komatsu engine, there's no finger-pointing between the equipment manufacturer and a separate engine supplier about whose warranty covers what.

New Holland: CNH Industrial's Own Engine Division

New Holland Construction's excavator lineup runs on CNH-badged engines built by FPT Industrial, CNH Industrial's dedicated engine manufacturing division. A mid-size New Holland crawler excavator, the E265EL, is documented running a CNH 667TA/EEG six-cylinder diesel rated at 186 horsepower. Like Komatsu's approach, this is an in-house arrangement rather than a third-party engine supplier relationship, since FPT Industrial sits inside the same corporate parent as New Holland Construction. The practical difference from Komatsu is organizational rather than functional: the engine comes from a sister division within CNH Industrial rather than from New Holland Construction's own direct manufacturing, but the warranty and parts-support chain still runs through one corporate umbrella rather than across separate companies.

Hyundai: A Mix of Cummins Partnership and a Growing In-House Push

Hyundai Construction Equipment's engine sourcing is genuinely the most mixed of the three. For years, Hyundai excavators across multiple size classes, including older-generation 210-class machines, ran Cummins diesel engines under a long-standing supply partnership between the two companies. More recently, Hyundai's newest-generation HX-series excavators have shifted toward engines badged under the Hyundai corporate family's own engine designation rather than Cummins, reflecting a broader push toward in-house engine sourcing on new-generation models. Exactly how that corporate engine-branding picture fits together across Hyundai Construction Equipment's full current lineup, including machines like the HW210A wheeled excavator BFC finances, isn't something we're going to try to definitively map out here, since Hyundai's engine sourcing and corporate engine-branding details vary by model generation and aren't uniformly published across every current machine. What's consistent either way is that Hyundai Construction Equipment stands behind its own excavator warranty regardless of which engine supplier built the specific block under the hood.

Why This Actually Matters to a Contractor, Not Just an Engineer

Engine sourcing isn't trivia. It affects three things a contractor genuinely cares about: parts availability in a given region, who you call when the engine itself (not the hydraulics or the undercarriage) needs warranty service, and how resale buyers in the used market perceive the machine's long-term reliability. An in-house engine, whether it's Komatsu's own design or CNH's FPT Industrial unit, generally means dealer parts networks are built around a single, predictable supply chain. A third-party engine supplier relationship, like Hyundai's historical Cummins partnership, can actually be an advantage in some respects, since Cummins parts and service networks are extremely widespread in North America, often more so than a single equipment manufacturer's own dealer network in certain rural areas.

None of This Changes What BFC Finances or How

Engine sourcing philosophy doesn't change BFC's underwriting approach to any of these three brands. A Komatsu, Hyundai, or New Holland excavator is financed the same way regardless of what's under the hood: based on the equipment's value as collateral and your business's ability to support the payment. This is really a maintenance-planning and long-term-ownership question more than a financing one, and worth factoring into which brand you choose precisely because it affects your total cost of ownership over the life of the loan, not because it changes your approval odds today.

Emissions Compliance Looks Different Depending on Who Built the Engine

Tier 4 Final emissions compliance (the current EPA standard for off-road diesel engines) gets handled somewhat differently depending on who engineered the block. An engine builder with full in-house control, like Komatsu or CNH's FPT Industrial, can design the emissions-control hardware, the diesel particulate filter, the selective catalytic reduction system, and the engine itself as one integrated package from the start. A manufacturer sourcing engines from an outside supplier has to integrate someone else's emissions solution into their own machine design, which historically has occasionally meant a slightly different service procedure or a different diagnostic tool requirement than the rest of the machine uses. In practice, all three brands covered here are fully Tier 4 Final compliant and this rarely causes a real-world problem, but it's part of why some contractors have a strong preference for one engine-sourcing philosophy over another based on past experience.

Parts Lead Time: The Question That Actually Matters Most

Ask any contractor who's had a machine down for two weeks waiting on an engine part what they actually care about, and it isn't corporate structure, it's lead time. A fully in-house engine program, where the equipment manufacturer controls its own parts inventory and distribution for the engine as well as the rest of the machine, can mean faster turnaround on a dealer-stocked common part. A third-party engine supplier with its own massive, independent parts network, like Cummins, can sometimes actually turn around a part faster specifically because that supplier's distribution footprint is larger and more geographically dense than any single equipment manufacturer's own network. Neither model wins universally; it depends heavily on your specific region and which dealer or service network is actually strong near your jobsites.

What This Means for Resale Value Down the Road

Used equipment buyers, and the lenders financing them, do factor engine reputation into resale value, even if it's rarely the headline consideration. A machine with a widely trusted, widely serviced engine tends to hold value slightly better in the used market than a comparable machine with a less familiar engine, all else being equal. This has historically worked in Cummins-powered equipment's favor in some used markets, precisely because so many buyers already know and trust that engine from other equipment entirely. It's a real factor, but a secondary one behind hours, maintenance history, and overall condition, and not something that should override the brand and model decisions that actually fit your daily work.

Choosing a Brand Based on More Than the Spec Sheet

A contractor deciding between these three brands for a first-time or next excavator purchase should weigh engine sourcing alongside, not instead of, the factors that usually drive the decision: dealer proximity, attachment compatibility, operator familiarity, and purchase price. A contractor in a region with strong Cummins service infrastructure but a thin Hyundai dealer network, for example, might find that engine-level service is actually easier to access than hydraulic or undercarriage service would be. Asking your local dealer directly how engine warranty claims are actually handled, who you call, how long parts typically take, is a more useful question than assuming any one sourcing model is automatically better across the board. None of the three approaches here is objectively wrong; they're different tradeoffs that suit different operations.

Talking to Your Mechanic, Not Just Your Salesperson

A sales conversation about a new excavator purchase tends to focus on bucket capacity, reach, and sticker price, and rarely gets into engine-service specifics unless the contractor asks directly. Before financing a specific machine, it's worth a short, separate conversation with whoever will actually be servicing it, your own mechanic if you run one in-house, or the dealer's service department if you don't, about what engine warranty and service actually look like in practice for that exact model. That conversation surfaces practical details a sales brochure won't: typical turnaround time on a warranty claim, whether loaner or rental coverage is available while a machine is down, and how far the nearest engine-certified technician actually is from your usual jobsites.
