Cub cadet 100 PTO

[Ewilliams]

I am in the process of rebuilding a K-241 off of a 100. I am having a problem getting the PTO clutch off the crankshaft. I can not get at the 3 set screws because they are under the drive plate. Any help would be greatly appreciated.

Thanks,
Earl

If your strong enough, push the button with your thumbs and turn the PTO until it lines up with the slots, or put a 3-jaw puller on it and crank it SLOWLY untill you can spin the PTO freely. After you line up the holes with the slot, unscrew it and its stuck in place. Also when you get the set screws , there's usually debris down inside, good to flush out with compressed air, and there's not 3, there's 6 total, there one on top of the other so two in each hole!

Yup, just what mstetar said.

I finally got all mine out. I had to drill one though.

You might save yourself some headache if you run a bottoming tap down to the back end of the setscrew and chase the threads to clean up the rust. Once you get her broke loose, it'll come out easy the rest of the way instead of plowing through the rust. You can make a bottoming tap from an old plug tap using a grinder and some patience.

P-Blaster is your friend. Use lots of it, and use a high quality allen wrench. Once you wreck the hex, it's drill time. Use a scribe and dig out to the bottom of the allen socket so your allen wrench gets full engagement. Obviously don't use the ball end type allen wrench. Try tightening a wee bit before loosening, sometimes it helps break it free.

I thought someone posted an image of a cross section of the clutch set screws. If you can find that, it makes it all very clear. The outer set screws are standard flat or cup point. The inner set screws are pointed, and go just past the back edge of the pilot bearing in the clutch. If you drill it, beware on the inner setscrew as your drill bit will break through, catch on the edge of the bearing and wreck it. Been there.

Have fun!

I did as you all told me and I got them out no problem. I had to use the puller because my thumbs weren't strong enough (I'll have to work on that). I love this site. I have a lot of manuals, and I use them, but they do not tell you how to get parts off that have been on for 40+ years. I don't visit this site often, usually only when I need to find something out, and I feel bad about that. I guess when I get older and more experienced I can share the knowledge with someone else. Thanks again for all your help.
