Bobcat 463 bearing replacement

[Tamim]

Help please Hi, I am new to this forum and glad to see a lot of info, I have 463 the R/H side bearing went so I sent it for repair it cost me $1400 3 days later the other side went, so I decided to have ago, it took me a while because I didn't know what tools to use ,, but I learnt a lot, i took the axle out and got the inner bearing cup out of the axle tube but the outer bearing cup is stuck tried every tool possible, puller, slide hammer ,,, 3 days no luck, I am starting to think it's maybe welded or maybe I am not suppose to pull this thing out please help I can post some photos if needed to help me identify it.

Run a few beads of weld over the cup to try and shrink it to get it out.
Worst case, you can grind through it with a die grinder and a tungsten bur, but that is the very last option.

Thanks Tazza, yes haven't thought of that I will try today, I am having issues posting a picture, how do I tell if this is a cup it's my first time and can't find any pictures of the inside of a tube. it actually has two edges and same width as a cup but very warn, all I found is pieces of metal when I took the axle out. . Cheers

Posting pictures can be a little tough... Look up my profile and send me an email, see if i can sort it out for you.

Sorry for the delay.
Got the pictures, the bearing cups are still in there. Run some welds around it, see if you can get it collapse enough to come out. The inside of the tube should be flat, no ridge like this one has (bearing cup). The axle tube end should essentially look like:
---------_____
Not -------|_________
If that makes any sense

Thanks, very helpful, I finally got it out, welding didn't do it as I am not really good with welding, but I got that grinder you mentioned with a $25 bit which did the trick, I should be ok now to install it , the whole process cost me $300 in tools + $200 parts but still ok as the tools will be very handy and saved $900. I am now trying to make a tool to push the inner bearing into the cup. Thanks again

Glad you got it out.
To pull them in, if you have a mate with a lathe, get him to machine a disc about 1/2” thick or better, just a little smaller than the OD of the cup, drill a hole in the middle and use threaded rod with nuts to pull them into place.
I made mine to accept a pulling porta power ram. But the threaded rod will do the same job.

Just finished yesterday thanks Tazza and its all good, couldn't do without your help, I just noticed that of the RH arm when it's down is very close to the front wheel about 5mm but the LH side is about 70mm. Doesn't look good not sure if it's to do with any hydraulic adjustments, any idea what could be the problem.

No adjustment, but i'd check the tyre diameter first. Get a rope or something like that and warp it around the tryes to ensure they are the same diameter.
If they are, it could be that the arms are bent or have been broken and repaired incorrectly in the past.

Not sure of the problem, sometimes the gap changes in size, maybe if machine is sitting level on the ground or leaning to one side !! Not sure, i will keep checking, I been working with computers for 20years, selling, repairing and upgrading computers and laptops, if you need any support in this field I am more than Happy to help.
