    No holes on the lower............those holes don't go thru............

    But there is a slot on each side, under what is left of the old bearing..............................

    You simply need to take the triple to a press and press the stem out of the lower clamp.

    I have also successfully heated the triple and driven the stem out of the lower triple with a BFH, but I don't suggest this method as it is a serious PITA and you can really screw up the stem and other bits.

    Just get a bearing separator, think you can buy one from harbor freight or rent from autozone.

    I use an grinder (wall mounted) to grind almost through the bearing, let it cool and then give it a tap with a hammer, you can then use the the two slts as lever points.

    Or just make two deep slits on the race 180 degrees apart hit the slits with a chisel. It'll often crack the race in two halves that'll just fall off.

    Yes, that works really good.:thumb

    And my weird tool to push the inner races out of the steering head.....no laughing it has worked before.:wink: May be needed again soon or....make an "improved" version, I have "a few" more old wrenches.

    I used the "drill holes then knock them out with a punch" method on the upper, and that sucked. The one on the stem, I always had pressed off. I drilled holes once I had the race out on another bike, but the tool works very nice the last time I did it. I will probably stick with that, it just costs me a six pack to borrow it.:lol3

    It's magic. Same thing for swing arm bearings.

    grind then whack.

    it's like cutting glass, you score a line and create a failure point in the material

    I bought the Cycle Works tool for getting the bearing off. It's not really cheap, I guess, $39. But I like tools and if I ran a cord out to the bike I need almost 100'. When I take the air hose over to the bike it's about 60'. So I like to use a tool with out air or electricity. To each his own.

    If you are into working on your own bikes then the CW tool is the tool to have! That is for sure!
    I have used two tools to perform this prior to owning the CW tool.
    This Pry bar:

    And this peice of rebar that I bent and fashioned into a race removal tool that had just the perfect arch to reach the race lip and it popped right out:

    And the tip:

    As Elite-less (and others have) said buy the CW tool and you will have it for many future projects or be the hero friend that will save the day for a pal in need should the opportunity arise. :freaky

    Thanks for all the help in replacing the bearings & races......................
    After replacing the bearings & races, then using these guide lines on setting the adjustment:
    http://largiader.com/bearings/

    I find:
    1. the handle bars drop quickly from side to side,with the bike on the center stand.
    2. it fails "Snobum's" (http://bmwmotorcycletech.info/search.htm) tap the bars at 30 mph test.........

    Tomorrow I'll try & tighten up the bearings a bit..............I leave for Panama in 5 days....................

    I was lucky enough to have a little mig welder and this is what I did. About mid way down the race, I welded a bead all the way around, then took a long screw driver and used the edge of the bead to tap it out from the opposite side. I really didn't have to tap. Once I put the screwdriver on the bead and pushed, the race just fell out.
