Looking for help on removing the races for an 86 kxt frame. I can't knock them out with a punch as they are recessed so there is no material to hit. I tried cutting but do not want to cut into the neck if I go too far. Any suggestions?

this is a bearing race tool on rockymountain, i bet you could probably make something like this with a piece of pipe

I've used a pilot bearing puller in the past but not sure if it would have enough to hold on to. A pic would be helpful.

Yeah, I was going to say try a pilot bearing puller too. If you dont have one some automotive places let you rent tools for a small fee, then when you bring it back they return your money.

If your forced to cut, sometimes a dremel tool with a small grinding bit will work..... just eat away small bits at a time. Gives you a little more precision than say...a reciprocating saw!!! LOL

If you have access to a welder, had great success over the years with recessed bear races/cones/cups by stitch welding the races which causes them to shrink enough to fall out after cooling. In your case there is another option to tack weld a large flat washer to the race which then gives you something to tap on to drive out.

The Rocky Mountain videos are nice. I figured there would be some type of slide hammer.

Don't know the script with tecate but welding the race or something to it will work, always easier with some heat.

When I replaced the bearings on a Tri z I cut a couple of semi circle slots on the inside of the head stock tube top and bottom opposite each other with a die grinder so that a punch can get some purchase on the races.

Works a treat if you need them out without damage.

Thanks for the advice.
I grew a set and used a Dremel with a cut off wheel to cut the race.

Did it come out easily, that was the worst job I had on the bike, even after mine were cut I still had to heat them up and pound like mad to get them out, worst job ever!!

They came out somewhat easy. I used a sharpened chisel to cantilever it out. the tool would not have worked. One race is completely countersunk and the other is not much better.

I had to do the same thing on my old PE175. I learned that bearing races make REALLY sharp little metal bits when you grind them with a carbide burr. Ouch!
