Mechanically it should drop right in,providing that the new motor has a wheel Horse oil pan with the threaded mounting holes on the left side. If the new engine has a magneto ignition you should not even have to change much wiring. 4 Share this post Link to post Share on other sites

953 nut 55,394 #4 Posted December 2, 2020 Presuming your replacement engine came from a you can download the wiring diagram for the donor tractor and follow it. If it wasn't a then you can post the engine Spec Number here and we can help find a wiring system that will work. Presuming the replacement engine is a big-block I'm reasonably certain that the K-301 and K-321 block will fit the oil sump from the M-12. 1 Share this post Link to post Share on other sites
