About This Part
Timing chain tensioner rail assembly for the BYD Song Pro DM-i Champion (2023-2025), Song PLUS DM-i Champion (2023-2024), Seal DM-i (2023-2024) and more. This curved plastic guide, also known as a chain tensioner guide or timing chain slipper, rides against the timing chain in the engine bay to hold tension and keep the chain quiet. It carries OE 12798717-00 alongside reference 472QA-1021140. A grooved or cracked rail lets the chain slap, so inspect it during any timing service.

Frequently Asked Questions: OE 12798717-00
Which reference should I be matching against my old tensioner rail?
The OE number here is 12798717-00, and the same rail also carries the reference 472QA-1021140. A part carrying either marking is this part. Mouldings pick up oil and heat, so the number on the one you have removed may be hard to read, and it is worth cleaning before you conclude the numbers differ. If neither reference appears, look your car up in the fitment table on this page first. Where doubt remains, send a clear photograph of the marking through the quote route and we will match it for you.
How far ahead should I order this rail?
Delivery takes 8 to 25 days from your order to your door. Work to the total when you are deciding whether to strip the engine now or later. If the car is your only transport, order the rail and wait for it to land before booking any workshop time, rather than the other way round. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What is the tensioner rail made from?
This tensioner rail is plastic, in black, and supplied new. Store it flat and in its box until the engine is open. No fitting sequence or tension figure is published by us for this rail, so use the manual for your own engine. Check the OE number 12798717-00 against the old one first.
Where does the tensioner rail sit?
This rail sits in the engine bay, under Engine in the Timing Drive group, so the job is done under the bonnet on the engine itself. How much has to be removed to reach it depends on the build and is not something we publish, so follow the manual for your own car. Confirm the build in the fitment table on this page before you order, and once the old rail is out, hold the OE number 12798717-00 against it so you know the new one matches.
Why is there just the one version of this rail?
Only one version of this rail is offered, the Original/Genuine part from BYD, at the price on this page. There is no Aftermarket line for it because no aftermarket source has been taken on against this reference, so the tier question does not arise. If you have seen something quoted elsewhere under 472QA-1021140 and want our view, use the quote route with your car details. We will tell you whether an equivalent can be sourced for your build or whether the genuine rail remains the only option.
