Removing pulley from PTO shaft?

[sgraber]

Quick question: how do you guys normally get a pulley off of the PTO shaft? I had to use a chisel to break it free and slowly pry it off.

Held on by three bolts. Pull those bolts. There are two other holes in pulley that are threaded. Screw two bolts into those holes. Keep turning them and they will push the pulley off the hub

If I'm not mistaken, Barnyard has a video in the how to section on this procedure

Most taper bushings have a second set of tapped holes which you can thread the bolts that hold it together into to separate the bushing from the sheave. It looks like your bushing doesn't have those (maybe it has 1? can't tell from the photo). In lieu of a chisel, I have used thin wedges cut from oak and drive them between the bushing and the sheave/sprocket/whatever. They deform somewhat and can split, but don't mar the surfaces of the bushing or the sheave like a chisel would. Perhaps there's an even better way.

EDIT: Tmays beat me to the punch...

Too late for this time, but here is the video from the How To Forum for the next guy.

If you look closely at the pulley and hub that I have in that picture, there are only three holes in both (all threaded). There are no additional threaded holes in my setup. The pulley was lined up with the hub holes and held onto the hub with three bolts. Looking at that video, I think the previous owner put the hub on backwards as it was flipped 180 and the wide portion of the hub was placed onto the PTO shaft first. I had a heck of a time getting that pulley and hub off!!! I thought I was going to break something with as hard as I was having to hit the chisel to pry it out.

Do you think it would be worthwhile to machine and tap 2-3 additional holes in that hub for easier separation?

Yes, if you think you will ever have to remove it again. I think those bushings for the Cub spline are hard to come by and you don't want to risk breaking one. Adding tapped holes to bushings like this is a common modification. Tap them the same as the bolts you removed and you can use the same bolts for future removal like Barnyard's video shows. I'd go a step further and brush a little anti-sieze onto the PTO splines and bushing taper before reassembly to ease future removal.

Good call. I'll definitely do that! Thank you for your help!

Also, the correct hub is still available.

Good to know. Thanks Dan.

Actually, I may have mis-spoken. The one I was thinking about is the four hole version as seen in Barnyard's video.
