Help, the hay needs mowed and I am trying to change a bearing on the roll on my hesston 1091 mower-conditioner. I got the collar off, but can't get the bearing off the shaft, is there any methods to try without using a torch which could potentially damage the shaft. Thanks.

You can easily cut the nut off a bolt and not touch the threads. Try one for practice. As the others have said go parallel and its easy.

i agree with the others. torch is the way to go. done carefully you won't hurt the shaft. These bearings are very hard and you can break them cold with a hammer but I don't recomend this method. small pieces can fly out and hit you; penetrate skin; grown men have been killed this way

Don't even use the "blow" element of the torch at all. I've taken I don't know how many bearings off and have yet to "cut" one off. Get a big hammer and a big, freshly ground chisel and lay them very close to hand .Turn the torch up real high and put your hand under the "blow" lever so you lock that funtion out. Heat the inner race good and hot in one spot the width of the race, shut off the torch, grab the chisel and quickly chisel ACROSS the bearing, wedging the diameter apart. When you do this it releases it's grip and at most is a ton easier to tap off with a hammer. Done right the race will be totally loose. The key to this is heating the race quickly, thus not allowing time for the shaft to heat up. Smack that chisel as hard as the shaft structure and your abilities to be safe will allow. Chisel until the race cools enough that it can't be deformed easily, just one might do it but usually more. You guys won't believe how well it works. Loren.

I own a combine, so I own a torch to cut bearings off.....

As others say, cut part way & you can chisel it off.

What works for me is to cut parrellel to the shaft - heat the bearing race, & cut. you are never pushing the heat towards the shaft this way, I haven't damaged any shafts so far.

Just how well do those bearing pullers work? Very little metal to grip on, and don't you need a sleeve for each & every size bearing? Once the bearing is really froze on the shaft....

The torch shouldn't scare you- just turn down the pressure a bit and go slowly. Cut down parallel, not 90 degrees to the shaft. When you get close, let the heat bubble the remaining metal of the bearing, without using the cutting lever. That tiny bit of separation between the bearing and shaft will keep it from burning through to the shaft. Lower oxy pressure will do less blasting of the cut material. Cut through both sides of the bearing if necessary. Over the years I've cut hundreds of bearings off and have yet to ruin a shaft. (Have left a few scars though). Shine it up with emery cloth and it's ready for the new bearing.

Been through that movie myself. I took mine off with the torch, don't cut all the way down to the shaft, but put a big chisel in the torch cut groove and hammer the snot out of it. It helps to slit both sides of the bearing to give to a place to crack. If you're still nervous about the torch, you can also slit it most of the way with a small abrasive disk cutter, commonly called a Whizzer. A Dremel tool is a possibility, but slooooow.

There is also specialty puller that is made to lock on to the collar groove on that type of bearing. I can't remember the name, but I saw them several years ago in Farm Show Magazine. I know they were pretty expensive.

I read an article by a mechanic who routinely got this kind of work from guys who didn't want to cut the bearing off with a torch. He'd take the shaft back into the shop, and cut the bearing off with a torch...

Try a bearing puller.(not a two or three leg puller). This should be available from your local hire shop and is specifically designed for removing bearings from shafts. If you have a reasonable amount of machinery they are a worthwhile investment - also handy for removing tight tractor steering wheels!!
