Track Wheels: Pressed on Bearing?

'97 VMAX 600 SX: I am replacing some spent bearings on a couple of roller wheels that ride on the bottom of the track attached between the sliders. One was still intact, but the bearings were obviously needing replaced, and the other was separated and the wheel was dangling loose. I have tried prying, hammering, twisting, and chiseling, but can't get the old bearing halves off the shaft or from inside the wheel. Are these pressed on/in? Or am I dealing with corrosion? Whether or not helpful, pics are included. Any help would be greatly appreciated!

Forgot to mention I have both circlips off on each of the wheels. Even the bearing that is still intact (w/ wheel) won't budge... I am soaking now w/ liquid wrench, and was going to apply heat tomorrow if it wasn't pressed on. Thinking of buying complete shaft/wheels if it was!
 
It looks like corrosion, you might have to cut the one off the shaft. Try a puller if you get one. If you can get it off the shaft and it's still in the wheel, press it out. If you don't have a press use a socket and a bench vice.

I can cut it off the shaft (Dremel, cutting wheel, etc.), but you can't press it out of the wheel. The wheel only allows the bearing to go into one side, and is smaller on the other side to act as a "stop" for the bearing. Prying is about the only option, as using a punch or a chisel is difficult at best due to the angle (you have to line the tool up at about a 45 degree angle on the small end / opening of he wheel).
I am solving this problem for now by purchasing the whole setup used from Viperkings' SRX partout, but may putt around with it to see if I can make it work again. I bought the replacement bearings, I might as well put them to use!
 
i would cut that race off as you mentioned being careful not to damage the shaft.

when lacking availability to a press, what has worked for me in the past is a the vice, wood blocks, a piece of steel pipe and a sacrificial bolt. vice when both wheels are on, pipe when one wheel is on.

find a bolt that you wont be using again with matching threads to the shaft. thread it in and use the bolt as a strike point for your hammer. you wont harm the shaft if done properly. line the wheel up over some 2x4's atop the vice and strike away.

same applies with the pipe method. select a length suitable to the shaft with room for fallout and a diameter close to the inside portion of the wheel. be sure and stuff some shop rags or similar in the bottom of the pipe to catch the shaft and protect it from the floor.

once your shaft is cleaned up and smoothed with some emery, reverse the procedure for the install. access to a press is best.
 
You could try what I used to do to get stubborn bearing races out of wheel hubs. With a mig welder, weld a bead on the inside of the race. When it cools the race should fall right out.

Now that's something I had not considered/thought of. Thanks!
 
I have time to work on this now that I have bought a used replacement, but want not only the experience but be able to use it again in a pinch.
