Does anyone have spare servicable rear hubs sitting around? I am doing a rebuild on the rear suspension and found out that the hubs have been staked at all the race locations. If you have or know of someone, please shoot me a PM or email rob at yzn1 dot com with details. Thanks, Rob

Robin,
I don't fully understand what you mean when you say; "the hubs have been staked at all the race locations," however, if the staking
is retaining the races in the hubs take them to a welder and have him run a bead around the ID of the race. This should release the
race from the hub.
I read this trick here and I think it was Larry W. that came up with that idea.
Yep I was right!

That is really neat! It would be interesting to hear the story about how someone came to try that out.

I have always done that to remove stubborn internal bearing races. I
believe that my Agriculture Shop instructor showed me how to do it. Another
cool trick that he demonstrated at the same time was how to weld two
electrodes end to end, then insulate them with rubber fuel line to keep
them from arcing to the side so you could reach down into a deep housing to
weld a bearing race for removal. He knew a lot of tricks like that. That
was about 1957 or so, before wire feed welders. This was a buzz box Hobart
with different sockets to plug into to get different heats. He could use
chunks of rebar for electrodes at very high amperage as well. Also showed
us how to use coat hangers for oxy/acetylene welding if you run out of
sticks. Handy stuff if you are out on the job site poorly equipped, like
most farmers.

Hi Rob,
Staked meaning someone center-punched the hub metal edge at the race about every 1/2 inch around the hub/race to deform the metal enough to hold the race tighter. I will go to my local bearing shop and see if I can get slightly oversized races. I guess the the person that worked on the coach earlier seemed to be worried about the races spinning in the hub.

Sir, lock tite makes a green race retainer and works. Must use heat to remove tho. However a new race and bearing if kept greased should last a vary long time. I agree it is not the recomender way to do it. Welding a bead in the race to remove is a must when dealing with some aluminum hubs as in motorcycles.

I have heard about the green loctite but have never used it--good to know that it works. I was able to get the races out--they were tight. If I try to reuse the hubs as is I will have to file out the areas that have been punched and see if a new race will fit tight enough.

Update:
I have a set of hubs shipping out to me next week. FYI, info from my local bearing supply house--the large bearing series has different sized outer diameter races so if you do have one spin you can deal with that by replacing the bearing/race set with the larger diameter race in that series and having the hub machined for that race. The smaller wheel bearing (outer) would be more difficult--that bearing series does not have an option for a larger outer race and one would have find a different bearing/race set. I have not mic-ed my hubs to see why they were staked yet--they might be within tolerance and just need to be fixed at the edges.
