Crankshaft Thrust Washer Set for BYD Song Pro DM-i & Sealion 05, OE 12798677-00

This reference covers a broad range of BYD models, so the model name will not settle it. Take the fitment table on this page and match your model with your build year before anything else. Then compare OE 12798677-00 with whatever reference your engine paperwork or old packaging carries, since a washer itself is unlikely to be marked. If your car is not in the table, or you are between variants and cannot tell which you have, send a photograph of the old part and its label through the quote route and let us confirm the reference for you.

Check it against both. Thrust washers rarely carry a legible marking themselves, which makes the number on your paperwork the thing to compare. If what you were given matches neither of ours, do not work it out from the look of the old part. Send us the number with your model and build year and we will identify it here.

Delivery takes 8 to 25 days from your order to your door. Plan the engine work around that. Small parts like these are often the ones holding up a rebuild, so order them at the same time as the larger items rather than last. Ask us if a specific date matters. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.

These washers are metal, without any further specification given. The useful implication is in how they are treated before they go in. They are supplied new, and the bearing faces want to stay untouched by grit or by bare fingers where you can avoid it. The packaging details for them are shown on this page. No thickness or clearance figure is given, so none should be assumed.

The position on record is the engine bay, and within that they belong with the crankshaft and bearing assembly of the engine. Reaching them means the bottom end is already open, which is why they tend to be ordered as part of a planned rebuild rather than on their own. We publish no fitting steps and none are supplied. Do the fitment check on this page before ordering, then let whoever is building the engine confirm what else in the same group they want while the work is under way.

The Original/Genuine item made by BYD is all we offer for OE 12798677-00. Nothing sits in the Aftermarket tier against it, so the page shows a single version at the price shown on this page. That is a matter of what can be sourced for the reference. Where a second source exists for a part, both tiers appear and the decision passes to you. If you would like us to look for an alternative reference that covers the same application, use the quote route with your model and build year included.
