    Suggestions on removing steering stem bearing race from frame

    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?

    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 .

    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!
