ok, so im pulling apart my wheels this weekend on the 550. we opened up the backing plate to reveal a nicely installed and punched bearing retainer that has 4 notches (not nochez) machined into it to put a tool on to remove it so you can get to the bearing. it is also punched/tanged. im sure this was a factory deal. its similar to the triumph rear bearing retainer, but instead of holes, its 4 grooves cut across from each other. chris went through the tucker rockey catalog and there is no tool in there to remove the stupid thing. so, question is, anyone got one, and where did you get it from. i already checked at my local dealer tonight, and they 18 year old kid behind the counter didnt know. i figured i got him to cut some chain for me, and i wasnt going to push it. i cant balance my new tires until i can get some new bearings in. so its kind of a pain in the ass.

oh yeah, i found the ignition part i was looking for. emgo makes one just for this application! pipes come tomorrow. pics of the new scoot soon.

Joe C,
This sounds a lot like my XL600 bearing retainer. I too was baffled by this, so I axed one of the dudes that races these bikes how to remove it, and says he " just drill the punched spots enough so that they no longer hold the retainer in place, it won't take much..." then he says to me " I just make the tool to loosen and tighten the retainer out of some flat stock, I measure and drill through a scrap piece thats long enough to get some leverage on, and thread two bolts through just enough to seat in the notches on the retainer...." etc. etc.

Anyway, I did it and it works just fine, and it was quicker and more fun than buying an over-priced pin wrench from (insert your tool supplier here).

Hope this helps,

the thing is, it doesnt have just holes in it for a "pin wrench". it has about 3/8" grooves machined in it in a cross pattern. no holes. so the grooves are 90 degrees to each other. sort of like a gigantic castle nut, but with 4 grooves. and its shallow/ maybe 3/16" or 1/8" and recesses into the hub. i was thinking something that goes onto the end of a ratchet or with a bolt on the end. the thing is, its aluminum, like they all seem to be, and its been punched at the threads in 4 places. so the seam where it meets the hub has punches or a tang pounded into it. see what i mean??? i have the triumph tool too, but its useless for this. i tried using a punch to spin it out, but it just burried itself in the retainer. i also tried a large screwdriver, but it did the same thing. the one on my bonneville screw in, then has an alan bolt that locks it into place.

id taker pictures of it, but i put it back together so i could ride it. i'll have to look at my other later wheel and se what it has. if its the same, i'll take a pic of it.

Dude,

I shouldn't have said pin wrench, 'cause that's a slightly different tool, for using on a crenellated nut, like on a steering head retainer. What I meant is, take a piece of flat stock steel - 1/8 x 1 x 12 or so inches long. Lay it flat, centered over the retainer, mark the spots where the two opposite notches are, drill and tap the marked spots using a 3/16 or 7mm bolt (assuming either one would fit in the notch on the retainer). The tool should look like a flat piece of steel with two bolts threaded part way through.
Then using a fairly large bit, drill out the peened sections on the retainer, you shouldn't have to drill very deep at all, just enough to get past the punch marks. There's not a whole lot of torque on the retainer, so it won't take much effort once you've drilled the punch marks away. The tool is handy for when you put it back together though. BTW, the retainer has the axle seal in it.
If this is not correct, then never mind.
