Does anyone know where I could locate an engine for a John Deere 644 b loader?
It is a 6cyl turbo I believe 531 ci.

Someone told me that they are buying JD combines with engines that will drop into JD loaders. Just sharing.

I dont think you have a 531 engine. If its an a or b its probably a 404, the later ones had a 466. If you had a 531 you could tell by the fact it didnt have enough power to get out of its own way and it would have had a ring cast on it where they attatched a chain when used as an anchor.

It is a 644 B, I'm not sure what year it is though. As for th 531 c.i. I was going by a manual I found online. As for the power it has never had much, it's my Father-Inlaws machine and he has never been happy with it. The engine locked up on it the other day but he tried it again yesterday and it started, but might have spun a bearing. I'm not sure if we will be rebuilding it this winter or find a donor as Cat suggested. If you come accross something that would work please let me know.

I stand corrected, the 644 & 644a had a 404 the 644b had the 531 and everythng from the b on up had the 466, so you are correct that is the engine you have, which is unfortunate becasue its a huge pig and expensive to overhaul. I would look for a 466 out of a junk yard if I was you a better motor and it had the ability to get out of its own way.

531's are kinda hard to find, find a combine  404 or 466, but you will probabbly need mounts belhousing etc from another machine that had that engine in it
