Oil Pump Sprocket for BYD Xia & Song Pro DM-i, OE 12798662-00

This sprocket appears against a long list of BYD models, which makes the model name a weak test on its own. Work from the fitment table on this page: locate your model and your build year, then hold OE 12798662-00 against the number on the sprocket you are taking off. Oil circuit parts get revised through a production run more often than buyers expect. If your car is missing from the table, or your year falls near the end of a range, raise it on the quote route before anything is agreed.

The part you have may be marked 472QA-1011011 rather than 12798662-00. Both references point at the same item, so a mismatch with the title is not a reason to walk away on its own. Wipe the face of the sprocket and read the marking properly before you compare, because oil film hides characters easily. If what you find matches neither reference, tell us exactly what is stamped on it together with your model and build year, and we will check it here rather than leave you ordering on a guess.

Delivery time is confirmed with your quote. It is also worth laying the new sprocket alongside the old one before fitting starts, just to confirm the teeth and bore match what came off. If timing matters because the car is off the road, use the quote route on this page and tell us before you order. The shipping cost is confirmed with your quote.

Metal is the material for this sprocket. On a part that runs inside the oil circuit, that mainly affects handling. It arrives new and dry, and it wants to stay clean and free of grit until the moment it goes on. No alloy specification is quoted for it.

The mounting position on record is the engine bay, on the oil circuit side of the engine rather than anywhere you can reach from the cabin. Getting to it means working at the engine with covers off, so it is worth pricing the labour before the part is agreed. We publish no fitting steps and none are supplied with the listing. Confirm your model in the fitment table on this page first, then let whoever is doing the work tell you what access looks like on your particular build.

Not at the moment. Only the Original/Genuine version is listed for this sprocket, made by BYD, and no Aftermarket version is offered against OE 12798662-00. Where two sources exist for a reference, both tiers show on the page and you pick between them. Here there is one version. Since this item also has to move under restricted transport rules, the sensible next step either way is the quote route on this page. Include your model and build year so we can answer on your actual car rather than in general terms.
