Engine Crankshaft for BYD Song Pro DM-i, OE 12841504-00

This one covers a wide spread of BYD models, so the model name on its own will not settle it. Go to the fitment table on this page and match the exact variant and year. The reliable check is the OE number 12841504-00, or the alternative reference 472QA-1005101, read from the unit coming out. An engine is far too much work to open twice, so if neither number is legible on your old part, send a photograph of the old part and its label through the quote route and let us confirm it before anything is ordered.

Both can be. If the number on your invoice, your old part or your workshop's quotation matches either of them, you are on the right page. If it matches neither, send it to us with a photograph of the old part and its label through the quote route instead of assuming that a near match will be close enough. Keep the old crankshaft until the new one is fitted, in case the two need comparing.

Delivery takes 8 to 28 days from your order to your door. For work of this scale the sensible order is part first and workshop booking second. There is nothing to gain from having an engine in pieces while the parcel is still travelling. If your dates are tight, ask through the quote route before ordering so you are working from a real answer.

This crankshaft travels as a standard box rather than anything a letterbox will take. The packaging details are shown on this page. Give a delivery address where somebody can receive it and move it safely, and have a bench or a trestle ready before it turns up. Look the outer box over for transit damage while the driver is still with you, and open it at working height so the part is never lifted off the floor.

This crankshaft is made of metal. It is a solid, heavy component, and it will not forgive being knocked against a bench edge or dropped, so decide where it is going to sit before you lift it clear of the box. Handle it on a flat, stable surface rather than balancing it on an edge. Check it against the old crank and against the fitment table on this page before it goes near the engine, since crankshafts can vary between similar engines.

This part sits in the engine bay, and it falls under the engine itself. That is the practical point. Reaching it means engine work under the bonnet, not a job done from beneath the car with the wheels off. There is no left or right side for this one, so a given car takes a single version and there is no handed pair to pick between. Plan the job around everything that has to come off first, and confirm your variant on the fitment table before you order.

BYD is held as the manufacturer of the Original/Genuine version, and the aftermarket manufacturer is empty against OE number 12841504-00, so this page carries a single tier and the price belongs to the genuine part. On an engine component that is not a bad position to be in. If you would still like us to look under the alternative reference 472QA-1005101, use the quote route with a photograph of the old part and its label and we will come back with whatever we can source.
