Danco Belly Mower PTO Pulley Removal

[AL Farmall Boy]

Is it me or was this pulley installed "backwards" ? We had a time getting it off and was wondering my the center "collar" wasn't coming loose from the pulley. After trying the holes for the built in puller and using a brass hammer and heat, I finally put a jaw puller on it to try (being ever so careful to not pull to hard an break it) to get it moving and she slid right off. Once it was off I noticed it was installed in this orientation. A small jaw puller took the center collar off with no problem. This looks backwards to me! No wonder it gave a hard time coming off!

( in the pictures, the PTO pulley was installed as you see it, with that flange to the outside)

Definitely backwards.

Both the hub and the pulley have tapers that are intended to match when installed. And no doubt you are familiar with the two threaded holes in the bushing flange that are used with two 1/4" bolts to push the pulley off the bushing.
It is good that nothing broke when using the pullers. Putting the bushing flange nearer the tractor end of the PTO is OK but shorter bolts for removal may be necessary. Be sure that all of the bushing bore is on the PTO shaft-- no overhang.

This video illustrates the process. Perhaps others can find a better video.

Here is a video that shows how it's done on a Cub.

Maybe I'm misreading this but your last statement says the " the bushing was instaled as shown...with the flange to the OUTSIDE but it looks like the pictures show the bushing flange to the inside as Bus Driver describes...Sometimes it takes me awhile to catch on!! Oh well, the good part is you got it off without breaking anything. One possible reason this was installed the way it was is to achieve the best belt alinement with the idlers on the mule drive.

I have encountered several installed this way. I believe, as Stan said, that it was to gain the best belt alignment. So far, I have not had one that I didn't have room to thread bolts into the flange and remove the pulley. It does not leave a lot of room to work but it can be done.

Whichever way it is installed, the trick is to "push" the pulley portion off the hub, using the two 1/4"-20 threaded holes provided. If you were trying to pull the center hub off the shaft with the pulley still on, then it would be difficult to impossible.

I've seen them installed this way too. Another possibility for putting it on backwards is to get a better bite on the pto shaft, especially if the hub is worn at the outside edge. Some pto's shafts are especially worn on the outer end and a p/o was trying to keep the pulley from working loose. My pto shaft is that way and I believe it was because of the original drive pulley from the sickle mower. That pulley (original clamp style) was so worn and eroded I'm surprised it wasn't slipping on the shaft.

There is a raised portion in the center of the pulley only on one side. That is the "flange" I was referring to. I wasn't referring to the center collar/flange/bushing that locks it all in place.

Oh, OK I was looking at the "flange" of the bushing. Remember I said sometimes it takes me a while to catch on.

I think this is a glass half full or half empty kinda thing if what I think happened. The pulley IS facing the normal/correct way, the HUB was turned the wrong way. If you put the HUB on the wrong way then you need to be consistent and put the pulley on the wrong way as well. I guess there are some people that can screw up screwing up

If you have a set of calipers I'd measure the hub at the end and near the flange, and measure both sides of the hole in the pulley. I think there should be a slight difference in the two hub measurements and equally different measurements in the pulley hole. These differences give you a taper so the pieces fit together (just like two Styrofoam coffee cups stacked together). In your case somebody tried to put the two small ends together.
