Marshall muckspreader bearing

[Keithy1394]

The bearing on the end of the beam of our marshall muckspreader has collapsed this afternoon i removed most of it but im struggleing the get inner bearing off the shaft if anyboby has any ideas how to remove it with out damaging the shaft

Grinder. Cutting rotational and across it. Then hit it with a hammer and chisel! Eye protection too!
Unless you can get some bearing pullers to fit

As above, I just run slitting disc along opposite sides, obviously don’t cut into the shaft, then just knock a cold chisel along the slit with a club hammer. Bobs your uncle Fanny’s your ant!
MAKE SURE YOU HAVE EYE PROTECTION

That was what i was thinking i was just checking there was'nt something i was missing

Cut curved slots opposite one another and whack one slot with your cold chisel and it will fracture.
Try not to cut the main shaft though.

If you’re worried about cutting into the shaft a slower way is to cut into the bearing horizontally with cutting disc about half way down and cut a piece off then use a grinding disc and grind from top down towards the shaft slowly and stradily intill it becomes very very thin and you will see the outline of the shaft appear. It will knock off with chisel then. Other way is just cut it off with gas, as it’s thinner than the shaft it will heat up quicker and with care and experience you won’t touch the shaft.

It’s the heat I would be worried about.

If you start cutting vertically at front with cutting disc you cannot go all the way across
That collar is quite hard I would be afraid of cutting disc shattering
I would put a few runs of weld around collar

Arc weld around it and it might " fall off"

Ill try that less chance of damaging shaft

I usually grind the inner race rather than cut. No chance of cutting the shaft then. New grinding disc, some ear and eye protection. You’ll see it change colour and go purple as it gets to 1/2mm thick and then it will crack and come off with a good pair of heel bars. Don’t like to see cut marks in a shaft when someone else has been there before me

In which way? Bearings are easy to cut off or out of housings with oxy torch with a little practice, it’s just a matter of concentrating the heat on one point and blowing it through quickly. The bearing race is always thinner/lighter than shaft or housing therefore will accept the heat quicker. I’d have no quibble to burn any bearing off even inside transmissions etc
