Inspecting a Used Track System

A sequence, not a verdict

None of the three manufacturers in view publishes a wear limit. Not a lug-height minimum, not a service life, not an hours-to-replacement figure, not a list of what fails first. Camso publishes a break-in schedule and inspection intervals; Kimpex publishes an installation time and a swap time. Neither publishes the number you would need to hold a worn part against and say the word finished. That absence is catalogued with the rest of them on what nobody publishes.

So you are comparing rather than measuring: this unit against the other three, this tooth against the one beside it, what the seller says against what the hardware shows. What follows is the order to look in — some of it becomes unreadable once the set is unbolted and stacked against a wall — and the questions worth asking, because the most expensive facts about a second-hand system are held by the seller rather than visible on the steel.

Which is the one thing this page cannot hand you. Every judgement in the sequence below is a comparison, and the reference the comparison would be made against is not published by a manufacturer and has not been photographed here.

One structural fact governs the whole exercise, and everything below is arranged around it: the mount kit is machine-specific. The tracks are the generic part. The steel that joins them to a hub is not, and it is why a used system rarely moves from one quad to another as-is.

Steps 1 to 5: before you drive anywhere

Every one of these is answerable in a message, and any one of them can end the conversation before you have spent a tank of fuel on it.

1. Which machine did it come off?Make, model, model year, trim, and the exact wording on the fender badge rather than what the advert calls it. A great deal of this site’s Identify section exists because one machine is filed under several names, and a seller quoting a marketing name is not giving you a model.
2. What was that machine’s rear suspension — rigid axle or independent? Ask it in those words. This is the field the mounting hardware is selected against, and it is the fastest way to find out whether the hardware in the sale is the hardware your machine takes. Sellers frequently do not know; a seller who does is telling you something about how the set was looked after.
3. Which system is it, and what is on the plate? Ask for a photograph of the plate rather than a number typed into a message. A transcription with one transposed character resolves to a different generation of the same system, and two generations of Camso ATV system share one serial family with only the model year separating them — a 6622 serial is ambiguous is that problem in full. If there is no plate and no paperwork, an unmarked system in a barn is what to measure instead.
4. Is the mount kit included, and is it the kit for the machine it came off? Two questions in one sentence, and they have different answers more often than you would expect — a set that has already moved once may be carrying hardware for the machine before last.
5. Who installed it, and does the seller still have the machine? Dealer installation is a published warranty condition on the Camso systems, so the answer has consequences beyond curiosity. And if the machine is gone, everything in answer 1 and 2 is a claim rather than something you can verify by walking round the back of the shed.

Steps 6 to 13: at the hardware

Take the photographs before anything is moved. A set that has been unbolted and stacked has lost the two things hardest to reconstruct: how the mount kit sat on the hub, and which unit was front and which was rear.

6. Confirm it is a complete set, and mark it. Four units, front pair and rear pair, and they are not interchangeable. Masking tape and a marker pen on each unit, before they come off, is worth more later than any photograph on the phone.
7. Count the drive sprocket teeth, front and rear separately. Tape on the first tooth, count twice. The Camso rows publish the sprocket as a pair per application — 11 distinct pairs in the catalogue, and on 129 rows the front and rear tooth counts are different figures. The pair on a used set is the pair its original application specified, which is a fact about the machine it came off and not necessarily about yours. The Kimpex rows publish no pair at all, so on that system there is nothing to check a count against.
8. Look at the sprocket teeth themselves, not just their number. The set in front of you is its own comparison: four units, so run a finger down the tooth profiles on each and look for one that is hooked, thinned or worn on one flank where its neighbours are not. Uneven wear between units is worth asking about — it points at alignment or tension rather than at age.
9. The belts. Run a hand along the inside face and look at four places: the base of the lugs, where cracking starts; the outer edges, where a belt that has run out of alignment frays; the drive holes the sprocket engages; and any previous repair. Ask what the hour-meter reading was when the set went on and what it is now, and ask it as two numbers rather than one. Nobody publishes a figure that turns those two numbers into a verdict, and you are collecting them so that the comparison exists at all.
10. Every wheel that turns. Spin each road wheel and idler by hand, one at a time, and listen. Rock each one against its axle for play. Count them on one front unit and one rear unit and confirm the other side matches — a missing mid-roller is a part, and a part is an order.
11. Whether the belt runs on wheels or on a plastic slide, and if there is a slide, whether it runs the full length and how much of it is left. This also happens to narrow which family the set belongs to, which matters if the plate is gone; the discriminators are in the unmarked-system page.
12. The frames and the pivots. Anything welded, bent, ground or drilled, on any of the four units. Then ask what it was — not to catch the seller out, but because a repair with a story is a different thing from a repair without one.
13. Tensioners, fasteners and anti-rotation hardware, photographed in place. The anti-rotation arrangement is the part most likely to be incomplete on a set that has been off a machine for two winters, and the part least likely to be noticed missing until the day it is needed.

Two things this sequence cannot reach, so a clean inspection is not read as more than it is. Internal belt condition is not visible from the outside and there is no published method for assessing it without running the set. And a mount kit that is complete, correct and undamaged still says nothing about whether it was torqued correctly on the machine it came off — that is a question about an install, not about a part.

The mount kit is the part that decides it

This is the section worth the drive. Everything above is condition; this is compatibility, and it is where used systems mostly come apart as purchases.

The published application data selects hardware against an attribute of the vehicle, not of the track system. The clearest case is the rear suspension. On the Camso rows, rigid axle and independent are published as separate applications — 406 independent and 250 rigid, read 2026-09-26. No machine title is published under both, so each machine sits on one side of that line and the hardware follows the machine. The 733 Kimpex rows publish no suspension field, which means that on that system the catalogue gives you nothing to check against and the question goes to a fitment desk instead.

Camso’s own parts reference is the strongest available evidence that this is not a formality. It publishes suspension conversion accessories — independent to rigid and rigid to independent — matched against 8 serial families in 6 model-year bands, spanning 2007–2026, read 2026-09-26. A manufacturer does not tool a part for a swap that costs nothing. If the set in front of you came off the other kind of machine from yours, the conversion is a named, separately bought component, and the question to ask is which one and whether it is in the sale.

Two things to know before you try to check a set against that reference yourself:

• The conversion accessories are matched by serial family and year band, and 2 families the accessories name are not published in the serial reference at all. An owner holding one of those has a number the published lookup does not resolve, which is a real position to be in and not a mistake you have made.
• The published application rows name no install kit and no hub bolt kit as read 2026-09-26, so a claimed mount kit cannot be checked against published application data. That has to be established against the hardware and the hub, or by a parts desk with the live catalogue in front of it.

What you can do physically, on the day, is measure the hub interface rather than trust the description of it. The bolt pattern is two diagonals and a tape measure, and measuring your own bolt pattern is the procedure and the figures to write down. A pattern that does not match what your machine carries is not the end of it either — an adapter may exist, and it is a separate line on an order. What matters is establishing which of those two situations you are in before money moves, rather than after the units are in your trailer.

The published conditions follow the machine, not the system

A second-hand set carries no flags. The flags are published against an application — a machine and a system together — so a set that came off a flagged machine tells you nothing by looking at it, and the flag that matters to you is the one published against your machine.

In the application catalogue read 2026-09-26, 117 rows carry at least one published condition, across 6 distinct condition strings, all of them on the 656 Camso rows. The ones that change what a used purchase actually consists of are the ones that imply a second purchase or an alteration:

• Temporary body parts removal — published against 38 applications
• Temporary Vehicle modification — published against 36 applications
• Vehicle with cargo box — published against 19 applications
• Permanent interference — published against 16 applications
• Permanent vehicle modification — published against 14 applications
• Suspension lift kit required — published against 14 applications

Kimpex publishes no per-application condition data at all: every Commander WS4 record in this catalogue has an empty remarks field. The absence of a WS4 entry below means nobody has published a condition for it — not that none exists. Camso is the only manufacturer here that publishes these flags, so this page is necessarily a Camso view of the catalogue.

Two practical consequences. If your machine sits on a row flagged for a suspension lift, the lift components are a purchase the seller’s set may or may not include, and they are worth asking about by name. And if it sits on a row flagged for an alteration the manufacturer calls permanent, that is a fact about your machine that a second-hand system does not change. Camso does not publish what the alteration is, so ask the dealer what it involves on your model year before the money moves. The derived rows for your make are in Machines.

Warranty, on a system with a second owner

Worth settling before rather than after, because the published terms turn on how the system was installed and this is the point at which that history becomes somebody else’s.

Camso publishes one condition in the warranty text itself:

This warranty applies exclusively to parts and components of the track system and is valid when the track systems are installed by an authorized Camso dealer or distributor.powersports.camso.co warranty page, read 2026-09-26

Note what that sentence does and does not say. It states a condition about installation. It says nothing about who owns the machine, and nothing about a system sold on. Whether coverage follows the hardware to a second owner is a question for Camso, and worth asking them in writing before you rely on it. What the sentence does mean is unambiguous: a set you fit yourself in a garage is outside the stated condition, whoever owned it first. Doing it yourself and the warranty is that trade-off in full.

Kimpex is the harder case, because its own pages disagree with each other about the term. All three states were checked on 2026-09-26:

• The Commander WS4 product page published no term of its own, only a link to the warranty page.
• The Kimpex US warranty page published, for Commander track kits, a basic 1 year plus an additional 1 year on registering the product.
• A 3 year figure is in circulation for the same system, and no Kimpex-published page stating it was reached on that date.

Confirm the term in writing with the manufacturer before relying on any of the three. Registration is the detail that matters most to a second-hand buyer: a term that depends on the product having been registered depends on something the first owner either did or did not do, and you cannot see it on the hardware.

The record to walk away with

Whether you buy or not, this is what should be on your phone before you leave, and it is short enough to work from.

• The plate on the system, photographed, both locations if there are two.
• The year, make, model, trim and rear-suspension type of the machine it came off.
• Front and rear sprocket tooth counts, recorded as two figures and not one.
• Your own bolt-pattern measurements, taken from your machine rather than from the advert.
• The mount kit photographed where it meets the hub, from both sides.
• Whatever the seller said about hours, installation and repairs, written down the same day.
• Anything welded, bent or drilled, photographed with a scale in frame.

With those in hand the remaining questions are all of one kind: which parts, for which machine, against which diagram. Those belong to a parts desk with a live catalogue, and handing them over with photographs rather than with remembered numbers is the whole difference between a cheap second-hand set and an expensive one.
