Frequently Asked Questions: OE 12979910-00
How do I know this sprocket fits my Xia or Song Pro?
Fitment on timing parts depends on the exact engine and build, so checking by eye is not reliable. This one carries OE number 12979910-00, also listed as 472QA-1021013, so start there. Use the quote route on this page and send a photograph of the old part along with that OE number, and it will be checked against your specific vehicle before anything is ordered. That confirms it is the correct sprocket rather than just a likely match.
The number on my old sprocket does not match 12979910-00, what now?
Do not rely on a memory of the number, check the model and the model year exactly as shown on your registration document, since that is what confirms whether this sprocket is right for your car. If the details on the document match what this listing covers, the sprocket is correct even if the marking on the worn part looks different. If you are still unsure once you have checked the document, use the quote route on this page and someone can confirm it before you order.
How long will delivery take on this sprocket?
The delivery time is 8 to 25 days, from order to door. Given that wait, have the old part off the car and in front of you before you order, so you can check it against what you are buying rather than after it arrives. That way, if anything about the old sprocket looks different once you are ordering, you can raise it with us straight away instead of losing time on a wrong order.
What is this sprocket made of?
It is metal. If you want to check it against the part on the bench before you order, this sprocket is also listed under the reference 472QA-1021013, so you can match either number to what you find stamped on the old one. Working from the number, rather than the look of the part, is the safer way to confirm it is the right one, since sprockets from different engines can appear very similar at a glance.
Where does the exhaust camshaft sprocket fit on the engine?
This sprocket fits onto the exhaust camshaft, positioned within the timing drive in the engine bay. It carries OE number 12979910-00, also listed as 472QA-1021013, for the BYD Xia and Song Pro. Only one version is listed, so before ordering, check that number against the marking on your old sprocket to confirm it matches the position and fixings on your own car. It is made of metal.
Is this the only version of this sprocket available, or are there cheaper options?
Yes, only the original is listed for this OE number at present. That is simply what is listed today, not a statement that nothing else exists for this car. If you are after an aftermarket alternative priced up, ask us directly and we will look into it for you. Have the OE number and the details from the fitment table on this page ready when you get in touch, so we can check properly.
