CVT Belt Sizes: A Selection Guide Without a Size Chart

No belt dimensions or fitment chart are published here. Use the checklist in this guide to request identification and compatibility confirmation from the supplier.

Why there is no size chart here

A reader who searches for CVT belt sizes usually wants a chart: a list of belts, with lengths and widths, matched to a vehicle or a unit. This guide does not provide one, and the reason is simple and should be stated plainly. The company parts table, which is the only source for the part pages on this site, lists the CVT belt as a row with a name and a market note, and gives no size at all. No length, no width, no link count, no marking code. A chart built from general knowledge, from another manufacturer's catalogue or from a forum would not be a chart for this supplier's belt, and publishing it as if it were would mislead exactly the reader who needs it most.

Belt size is not something to guess from a name, and it is not something to copy from an unrelated chart. It is something to confirm with the supplier, for the specific row, in writing, before ordering. The rest of this guide explains what that confirmation looks like, so the reader can ask for it precisely.

What belt size even means

For a CVT steel belt, size is not one number. Ask the supplier which dimensions and identifiers are required to identify the belt, including its marking as it appears in the supplier's stock.

None of those dimensions is given in the parts table, so none is given here. The point of listing them is not to provide them, but to show why a single number from a search result is never enough. A reader who asks for the full set of identifiers can check the delivered belt against them on arrival.

The belt-or-chain question comes first

Before any size question, there is a row question: belt or chain? The parts table warns that the market often calls a belt a chain, and the chain row is a separate row for a minority of CVTs. A size inquiry that does not settle the row first is wasted, because belt sizes and chain sizes are not the same measurements, and a supplier cannot answer a size question for the wrong row. State the row in the inquiry, CVT Belt, and ask the supplier to confirm that the belt offered is the belt row and not the chain row.

The same discipline applies to the steel question. The assembly row is described as pulley-and-steel-belt type, and the steel-belt page is the steel sub-category of the belt row. An inquiry that says steel belt should ask the supplier to confirm that the belt offered belongs to that steel family. A supplier answer that only repeats the word steel, without confirming the row, has not answered the question.

Checklist to send with a belt inquiry

The part row, written as CVT Belt, with the steel-belt name where that is the family meant.
The supplier's own identification for the belt, exactly as it appears in the supplier's stock.
The dimensions and marking the supplier uses to identify the belt, and the marking to check on arrival.
The pulley set the belt pairs with, and whether the belt is supplied alone or with its set.
The quantity terms and the lead time for the belt row, confirmed in writing.
The packing details, confirmed in writing, so the delivered belt can be checked before fitting.

Send the checklist as it stands, and keep the supplier's written reply with the order. A reply that answers every line gives the buyer a record to check the delivery against. A reply that answers only part of the list leaves the unanswered lines open, and the buyer should ask for them before payment rather than assuming them.

What to ask the supplier

Ask for the supplier's own part identification for the belt, exactly as it appears in the supplier's stock, not as it appears in a third-party catalogue. Ask for the dimensions the supplier uses to identify the belt, and for the marking to check on arrival. Ask which pulley set the belt pairs with, and whether the belt is supplied alone or with its set. Ask for the quantity terms and the lead time for the belt row. Ask for the packing details in writing.

Ask those questions in writing, and keep the reply with the order. Request the identification, dimensions and packing details in writing. On arrival, compare the delivered belt's marking against that reply before fitting.

What to do with a belt you already have

A reader who already holds a belt, removed from a unit, has a better starting point than a reader ordering from a name alone: the physical belt carries its own evidence. Its marking, where present, is the first thing to record, exactly as written, including any characters that look unimportant. Its general dimensions, measured carefully, are the second. Its construction, steel elements rather than rubber, is the third. Send that record to the supplier and ask whether the supplier's belt row matches it, rather than asking the supplier to guess from a vehicle description.

Do not assume that a belt that looks the same is the same. The marking and the supplier's confirmation are the check, not the eye alone.

Common size mistakes

The first common mistake is ordering by vehicle name alone. This site carries no vehicle fitment list, and a vehicle name is not a belt size. Ask the supplier whether your vehicle information and existing part references are sufficient to identify the requested belt. The second mistake is ordering by a third-party part number without confirming that the supplier uses the same numbering. Ask the supplier whether a part reference from another catalogue matches the supplier's own identification for the belt row. The third mistake is ordering a chain when a belt is meant, or the reverse, because of the market habit noted in the table. The fourth mistake is assuming a set includes the belt, when the set row and the belt row are separate rows, and the set may or may not include it.

Each of those mistakes is prevented by the same habit: name the row, ask for the supplier's identification, and get the answer in writing. That habit is slower than clicking a chart, but it is the only habit that works when no chart exists for the supplier in question.

When a supplier cannot confirm a size

Sometimes a supplier cannot confirm a size from the information given. That is not necessarily a bad sign. It may mean the information is genuinely insufficient, and the supplier is refusing to guess, which is the honest answer. In that case, provide more evidence: the marking from the removed belt, the pulley set it pairs with, photographs of the marking and the belt as a whole, and any supplier identification from a previous order. If the supplier still cannot confirm, do not order on a guess. If compatibility remains unconfirmed, request further clarification before ordering.

The size of the belt you need is the size your supplier confirms, for your row, in writing, before you pay.
