yes they are the same engine both are 12.5 , you can get a reman engine through deere. everything will bot to the engine use the ecu from the engine you are using.
A reman has a 2 year warranty , we have had good luck with them. what happened to the other 12.5 engine.
I hope this helps
I think I would not swap ecu controllers unless you have a code saying there is a problem. You shouldnt get that code but if you do swap ecu controllers.
I am about 173 miles from st louis let me check. you could drive here but the reman has a 2 year no problem warranty. I can see what we get for one if you want to pick it up. I know we will need the other engine for a core. I think the overhaul kit is about. 10,000. I can see what we get on one if you would like..
I know we have just a water pump take pout the whole engine before, bearing went out and tore up every gear in the engine. They block out your number so I can't read it to call. let me know back here and I will try to help.
I checked with the parts man and he said 31 thousand and some change. It had a $5500 core charge . Please excuse my typing in the previous post, when I type on my laptop I think my fingers go numb.
As far as a new complete engine I didn't price one because it would have been higher. Another thing you might consider, with most deere parts if the customer puts it on you have a 90 warranty.
If the dealer puts it on you have a 1 year warranty. The point is, if you are doing this yourself, you might check into the warranty.
