Oil Pump Chain for BYD Seal 07 DM-i & Han DM-p, OE 12640662-00

Check your own car against the fitment table on this page rather than going by the model badge. This oil pump chain is listed across a broad spread of BYD models, and a model name on its own does not pin down the build. The OE number 12640662-00 is the reliable check if you can read it on the chain or its packaging. Where the old chain is already out and unmarked, send a photograph of it with the quote request and we will match it against the OE number before anything is agreed.

The chain you have taken off may be marked 476ZQC-1011200 instead of 12640662-00. Those are two references for the same oil pump chain, so a different number is not a mismatch on its own. Compare both against the marking on the old chain or the bag it came in. If neither reads across, do not guess. Send a clear photograph of the marking when you request the quote, and we will confirm the identification before you commit to anything.

Delivery time is confirmed with your quote. When it arrives, check the parcel is intact before you sign for it, and open it somewhere you can lay the old chain alongside the new one for a quick look. If anything about the parcel or its contents does not look right, tell us straight away through the quote route on this page rather than fitting it and raising it later.

The material is metal, which is what you would expect of a drive chain rather than a moulded part. It arrives new and unused. Keep it in its wrapping until the moment it goes on, and check the OE number 12640662-00 on the packaging against the number you asked us to quote. If the two disagree, tell us before it is fitted.

This one is fitted in the engine bay. It is the oil pump chain, so it sits inside the engine on the oil circuit rather than anywhere you can reach with the bonnet simply propped open. That is worth knowing before you plan the work, since it sits inside the engine bay rather than on the underbody. Confirm with your own vehicle which chain you are replacing, then quote the OE number 12640662-00 when you ask us for a price so we send the right one.

Only the Original/Genuine version of this oil pump chain is listed, made by BYD. No Aftermarket equivalent is offered for this reference, so there is a single option to consider and the price on this page belongs to it. Because the part is quoted rather than added to a basket, you will see that figure confirmed in writing before anything is agreed. If you want us to look for another source, say so in the quote request and we will look into it.
