MF-50
Hello,

I'm adding a MF-101 Loader to my MF-50. I ordered the pulley below and my crank pulley has what appears to be three holes with 3/8" threads. What bolts are supposed to be used? The bushings in the pulley I ordered are much larger (probably 1/2"). I've looked for shoulder bolts or other bushings, but can't find anything to work.
Maybe I need a different crank pulley? IDK. Any feedback would be a appreciated.

Thank you! I checked my crank and they are 3/8-16 UNC RH and it lines up, but bushings are 1/2" and bolts are 3/8".

I use to have a 9n and I love the M-50 with power steering. It's so much more of a tractor. Here's a pic of mine and the loader I'm adding.

Very nice M-F 50 looks like You did allot of work to her. I'm hoping too do a respray on mine this year hard to do when your doing work with the tractor most of the time. Here is a picture of my 50 working with my newer 2018 M-F 1526, & dump truck. Sorry I couldn't help You.IMG_20201003_134009.jpg

Just an update if anyone else needs help. I used Tee-Nuts from Tractor supply which worked perfectly to take the play out of bolt going through pulley spacers.
