In the earthmoving business, keeping machines operational is a top priority. Downtime isn't just an inconvenience — it's money lost. Whether you're running a fleet of 20-tonne excavators or managing a single machine on a tight job schedule, every breakdown hits your bottom line. So, when a track adjuster fails, the natural instinct is to source a replacement — fast.
But what if your usual supplier doesn't have the exact part in stock? Or what if you're trying to save money by buying a high-quality used part instead of splurging on a brand-new OEM option?
That’s where one of the most frequently asked questions comes in:“Can the track adjuster of a Volvo EC210 fit on a Hyundai Robex 210?”
At Vikfin, we get this question all the time. Let’s break it down.
First, What Is a Track Adjuster and Why Is It So Important?
The track adjuster — also known as the recoil spring or tensioner — is a vital component of the undercarriage of any tracked excavator. Its job is to maintain the correct tension of the steel tracks. Too loose? The track risks jumping off during operation. Too tight? You're putting unnecessary strain on your undercarriage components, leading to accelerated wear and higher fuel consumption.
The adjuster is made up of:
A grease cylinder
A tension rod
A recoil spring
Mounting brackets and guide plates
It’s one of those “out of sight, out of mind” parts… until it fails. Then suddenly, you’re stuck in the middle of a jobsite with an immobilized machine and a ticking clock.
Volvo EC210 vs Hyundai Robex 210: Same Weight Class, But Are Their Parts Interchangeable?
On the surface, both the Volvo EC210 and the Hyundai Robex 210 belong to the same class of excavators — 20-tonne workhorses that dominate in construction, mining, and plant hire fleets across South Africa.
In fact, these machines often share undercarriage components from third-party suppliers like Berco, ITM, and DCF. So, you might assume the track adjusters are identical or at least close enough to swap.
But here’s where it gets tricky.
The Challenge of Interchangeability
Even within the same model line, part compatibility can vary significantly based on:
Production year
Sub-model (e.g., EC210B, EC210CL, Robex 210LC-7 vs 210LC-9)
OEM design changes
Regional specifications
Key Differences That May Affect Compatibility:
Mounting Points: The bolt pattern, plate alignment, and frame fit must match exactly. Even 10mm off can be a deal breaker.
Grease Cylinder Length and Stroke: This determines how much the track can be extended or retracted.
Recoil Spring Strength: The force exerted by the spring must be appropriate for the machine’s track load.
Track Frame Profile: Even slight design changes in the track frame can mean the adjuster won’t slide in correctly.
At Vikfin, we've seen firsthand that not all 20-ton adjusters are created equal — even when they look similar. That’s why we don’t just go by looks. We go by measurements, part numbers, and experience.
The Only Way to Know: Compare the Specs
So, can you fit a Volvo EC210 track adjuster on a Hyundai Robex 210?
The answer is: maybe — but only if the specifications line up. Here's what we recommend:
1. Check OEM Part Numbers
Always the first step. If the part numbers match or are listed as interchangeable in parts databases, it’s a green light. If not, don’t assume anything.
2. Physically Compare Dimensions
When in doubt, pull out the tape measure. Measure:
Cylinder length (compressed and extended)
Mounting bolt distance
Spring diameter and housing size
If these dimensions line up and the recoil force is appropriate, then with some mechanical ingenuity, the part might be adaptable.
3. Ask a Parts Expert at Vikfin
Let’s face it: you don’t always have time to cross-reference specs or measure every component. That’s where our experience comes in. At Vikfin, we’ve stripped hundreds of excavators across brands like Volvo, Hyundai, Komatsu, Doosan, Hitachi, and Sumitomo. We know from real-world experience which parts can swap — and which can’t.
We won’t just sell you a part. We’ll make sure it works.
Why Used OEM Track Adjusters Are a Smart Choice
Whether you’re replacing a failed adjuster or proactively servicing your undercarriage, you’ll face a critical decision: New vs. Used.
Here’s why used OEM adjusters from Vikfin are a smart move:
1. OEM Quality at a Fraction of the Price
Our used parts are taken from working machines, fully tested, and pressure-checked. You get original factory quality without the original factory price tag.
2. Faster Availability
Ordering a new part can take weeks — especially for machines out of production. At Vikfin, we stock a wide variety of adjusters on-site, ready to ship.
3. Support for Older Machines
If your EC210 or Robex 210 is more than 10 years old, there’s a good chance OEMs have stopped producing some components. Used is often the only realistic option.
4. Sustainable Earthmoving
By using reclaimed OEM parts, you reduce waste and contribute to a circular economy. It’s good for your budget — and the planet.
Real Talk: When to Adapt a Part and When Not To
In some cases, fitting a used EC210 adjuster onto a Robex 210 might require:
Minor bracket adjustments
Welding new mounts
Shimming components to achieve the right preload
We’ve helped clients do this before — but it’s only worth the effort if the savings outweigh the labour. If you’re looking for a plug-and-play solution, you’re better off asking us to find a direct match.
We’ve got a massive inventory of used OEM track adjusters, and we’re confident we’ll have the right one for your exact machine.
What If We Don’t Have the Exact Part?
Here’s the difference with Vikfin: We don’t just sell parts — we solve problems.
If we don’t have your exact adjuster on the shelf, we’ll:
Cross-match other compatible adjusters from similar machines.
Call our network of suppliers and scrapyards across South Africa.
Offer a temporary solution, like a rebuild or retrofit option, to get you back in business.
And we always guarantee the best price. If you find the same quality used part cheaper somewhere else? We’ll beat it.

We get it. There are a lot of used parts floating around the market — some legit, some barely held together with duct tape and hope.
At Vikfin, we have a strict inspection process:
No visible cracks or deformities
Pressure-tested grease cylinders
Clean, lubricated springs
Mounting points intact and true
Every part we sell is something we’d trust in our own machines.
