Hello coltom welcome to YT! First off is it leaking engine oil when the engine is being worked or hydraulic oil when hydraulic pressure is being used? I will assume the latter. The Ms obviously did not originally have live hydraulics and the Supers so not show a break down of the pumps. I have attached the manufacturers online parts catalog for a Farmall 400 they use the same pump. In the Hydraulics section, look at subsection 371 and 373. Those sections will help you ID which pump you have. The one version has a block that bolts up under it and it is possible the leak you have is from them. They can easily be replaced with common hydraulic orings. YT has seal kits for them, find your pump number and call them. Just FYI, that link will also allow you to access the parts catalog for your M, just type Farmall M in the search bar. Also FYI Many parts are unavailable and many that are have outrageous prices. Also their site does not work well when viewed on a phone, or at least not an iPhone.
