The belt pulley on the M and the MD will be the same. You need to get yourself a parts catalog and you can see exactly what you need. It's fairly easy to the pulley shaft out. You just take the three bolts on the flange loose and the shaft two bearings, gear and seal all come out with the flange. You'll need a bearing press to get the bearings and gear off the shaft. I had mine out a couple years ago and decided only to replace one bearing. Don't do that shortcut. I'm going to have to take mine out again. These bearings go bad because of neglect. Water from condensation accumulates in the belt pulley oil sump (which is supplied from the transmission). The oil overflows back to the transmission, but there is a sump up at the pulley with no drain. If you never run the pulley the water eventually corrodes and ruins the bearings. Whenever the transmission oil is changed be sure to loosen the pulley flange bolts and pull out the flange to let the oil (and water) drain out. Then put a quart of so of transmission oil back in through the fill hole on top of the pulley housing.

To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
