Are we talking Apex on clutch side?
Your going to have to atleast pull the skid because you have all the pressure of the track pulling back on the axle otherwise.
Under the secondary clutch take out the boldt that holds the speedo sensor in place.Remove the skid.
There will be some torq screw in the bearing on the inside of the tunnel loosen those.Then on the outside of the tunnel loose the boldts the hold the bearing plate on.Now the bearing is free.With the chaincase on you will have to work it off it won't be as easy but you can do it.

Do you have the three nut's holding the bearing flanges off? You will have to take the set screw's completely out or they will not clear the hole to come off. Is the bearing loose on the shaft? I loosen up the track all the way and usually have no problem pushing forward on the shaft and sliding the bearing off.

If both torx screws are loose, you should be able to pry the bearing loose with a flat blade screw driver or pry bar twisting against the track drive & bearing collar. Helps to take the pressure off the drive shaft by pushing up and forward on the shaft. All this is assuming the bearing wasn't worn out, overheated ect... If so, thats a whole different problem requiring skinned knuckles and lots of cursing!

Both torx screws are out skid is out bearing may have been heated. My knuckles Deff show that this is not an easy job. I've loosened it about a 1/4 inch so far. Can't seem to get it any further.
Your going to have to tap it on the inside.Once you can get behind the bearing you can use a puller or pry it off.

Another option is to just shatter the old bearing with a heavy punch and hammer. Bearing races are very brittle. I've done this in the past. Once the outer race is gone I sometimes will cut a slot on the inner race with a cutoff wheel so it shatters even easier.
Just make sure you have safely glasses on!!

I always put anti-seize on the driveshaft before installing the new bearing. I know this doesn't help you now but maybe next time! If you got it to move at all, I would think with more cursing and bloody knuckles you'll get it off. Good luck!

Push the bearing back in towards the drivers, now take a fine scotch brite pad and clean up the shaft, see if that works.

In the future, you do not need to pull the skid to remove that bearing. Just loosen the track and that should be sufficient. Done it dozens of times.

Taking the chain case apart or off may give you a bit more room but the bearing still has to come off from the out side of the tunnel. If you can move it at all I would clean the shaft as said earlier with emery cloth and soak it with Kroils penetrating oil (awesome stuff) and work it back and forth, it should loosen up.
spray some PB-Blaster in the torx screw holes and let it soak for a half hour or so. The stuff works great.
