My DIY bearing retainer remover tool.
« on: March 10, 2009, 06:28:49 pm »
I share with you a bearing retainer tool that I fabbed up real quick tonight.  I wanted something that I can throw in the toolbox so I can have it for future projects and friends projects.
I used my 110V Craftsman welder and some scrap hardware that I had laying around. 
Sorry for the bad quality pics, they're from my cell phone....forgot the good digital at my apartment.  Oh, I was also rushing so the welds didn't come out that great but they hold.


For the pins, I just took some screws and put them in the drill press chuck.  With the drill press on, I used a file to grind down the screw threads to somethign that fit into the retainer holes... voila, a POOR mans lathe  :D

I must say, it's ugly but works great.

Has learned so far that..."complete" gaskets are never complete no matter where you get them, VHT Silver Case Paint is just as durable as painting your motor with chalk and cheap tire irons used with rim protectors are useless on 30 year old tires.

Well Done!

That's amazing, I have the exact same lathe!  ;)

Ugly matters not.


For extra stability, and a convenient excuse to use the welder some more, you could take an old wheel spacer and weld it to your tool, so that it's self-aligning.

I just popped in here unsure if the retainer even rotated or not - yup it does.

One question, did you have to do anything with the swage marks?  I thought I saw other people mention needing to drill them out before the retainer would come out.

Incidentally, my problem, which I spent all evening trying to diagnose as a chain problem, was a bearing that disintegrated on the first long ride after a chain adjustment.

YEs you MUST drill out the staked areas. Use a bit slightly larger than the staked hole and go down about an 1/8 to 3/16 maybe a 1/4".

A tool very similar to this can be made witha 24+" long strap. Drill 2 holes in it about midway, spaced apart to fit your retainer. Put the bolt and nut affairs in to create the pins. With the length of the strap you shouldn't need any more leverage.

Very clever, and yes you need to drill out those staked portions. They were put there to deform the threads to prevent the ring from vibrating loose.

Thanks guys; I did drill out the staked spots (only two each side form my particular assembly tech).  I put a couple short #10 machine screws through an aluminum bar to make my tool, it worked fine.  Then I learned that the other side is a different size; okay, I put another screw in the rod.  The retainer on the side with the explodified bearing was a little hard to get out, but with some extra love from a 16 oz hammer and nail set, it started to move.

Now, to get the rest of that bearing out....

  So exactly how much force should it take to remove this rear wheel retainer?  Reason I ask is I drilled out the stakes, had a tool tack welded together to fit the round holes, and made sure to spin clockwise.  This darn thing isn't moving.  And to make matters more difficult I already separated the hub from the wheel so it's proving challenging to find a way to keep the hub from wanting to turn when I torque it.
  I sprayed it with WD40 before I left for work, hopefully that'll help by the time I get home.  Any tips on securing this thing so it won't turn??

I think it should be fairly easy, mine were on a cb750. But losing the leverage of the wheel is unfortunate. Note to readers, always loosen the retainer before de lacing the wheel.

Only one of the 550 retainers is left hand thread I think. GOt the correct one? Maybe there is only one? Confirm with a 550 guy.
