Case 2290 hub bushing fight

Heiden · Aug 5, 2017

Tried to remove the hub bushing from a cast wheel of a 2290. Didn't work out, and wasted the bushing. :evil: Want to remove the cast wheel anyway. Any ideas? Haven't tried heat yet...

Lite on the heat and kroil oil. Oxidation got you. CM

After you applied pressure from the bolts which should have been done progressively in a circle in the threaded extraction holes, you should have got out your old trusty 10# maul and applied some persuasion to the wheel with it to break it loose. Looks like your only alternative now is the trusty smith wrench. You screwed yourself.

My brother had similar problem with a 4430. Made a puller with 2 big drawbars, 7/8 threaded rod
and a sleeve which would push the wedge and pull on the wheel.. Tightened. Beat with maul.
Tighten. Stripped rods. He ended up sawing off the wheel with a gas powered cut off saw. Hope
you don't have to do that. Not a pretty operation. The shop was black for years. Being cast iron
you can't gas axe it.

Build a fixture to push the hub out from the inside.

the Wedge is junk any way = why not Drill some Holes in it to Re leave the Pressure so you can get it apart with out Damaging the Wheel or the Axal ?

I made a puller / pusher fixture to push te wedge out from the inside of the wheel. Used six 5/8UNC rods. No luck. Drilled a hole in the inside of the weel into the wedge. I fitted a hydraulic fastener, filled with WD40 and connected a hydraulic pump to press oil/WD40 in to wheel/wedge mating surface. Still no luck.
Any other ideas? Torch is the last option i want to use...

Heiden, You are going to have use something round that pushes on the wedge only. The flat stock is self defeating. Glad I have not had this problem. Tom

That's what I've done. It's not visible in the pictures, but i've made a kind of collar between the fixture and the wedge, which pushes the wedge.

Got the b@sterd out. Added some extra threaded rods to pull on the wedge. Heated the b*tch. Finally came loose. Yeah.

Purposely waded back to find this post as I was curious if you got the wedge out and how you did it. Been down the same road with a yellow one. Ugly. Glad to hear you did!!
