Swingarm Bushing (Sleeve?) Removal
« on: April 06, 2011, 10:26:49 am »
I just wanted to add that the Hacksaw is a good way to take these steel sleeves out of your swingarm however I also want to add my two cents.

Make sure there is plenty of tension on that hacksaw blade and be sure to cut in a straight line, some of my cuts were straight but a lot were not (shaking head).

And its best to make your two cuts, it should only take two, about 40 to 50 degrees to give enough so those sleeves just fall out. I made my first two cuts too close together and I was micron away from starting to cut into the swingarm I thought I could just tap it out with a flathead screwdriver and all it did was just break a little piece off. That is pretty much why I had to do more cuts, hence all those little sleeve pieces in the photo.

Also, I thought since the cuts werent exactly falling out I thought I would fit a socket in the pivot shaft and give it a couple of whacks, hoping those cuts would break, but they didnt and I think I ended up doing more damage than good and that is the second picture. I think I may have wedged the metal inside the pivot shaft.  :-\

oh my. thanks for the heads up that looks like a mighty mess.

I may just try and press them out. I'm just not sure how to go about doing it. I have a blind bearing puller and a 20 ton shop press but... yea I think I need to develop a strategy first.

Here is a nifty tool a machinist buddy of mine made to get mine out.  It's basically 4 pieces plus a driver.  Pretty slick!
It took 10 years but she's finally done!

The tool is split in quarters?  Why?

So the pieces will fit through the bushing (assuming both sides are stuck).  Then the 4 pieces are reassembled inside the swingarm and driven against the inside of the stuck bushing with the long driver piece and a hammer.

Ksmith0034, do you by any chance have a technical drawing of the tool that I could use to have one made?

Nope.  I doubt he made any drawings.  He told me he used some scraps pieces and made a tool that fit.

CB650 removed mine pretty easily by a little tapping. Came out as good as new. I think he carefully used a longer socket extension? I'll get him to chime in. Installing the new replacement bronze bushing was pretty easy too once they were removed from the freezer.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Condition of the bike/bushings make a big difference.

I think my bushings have achieved oneness with the swingarm tube.  Unfortunately I pulled the trigger on OEM bushings before reading all about bronze bushings.  One question:  The pictures of the aftermarket brass bushings I have seen appear to have a lip on them.  Would these bushings replace all three parts: pivot bushings, pivot thrust bushings, and the felt ring?  Perhaps the picture was just an example and not the actual part.

yes.  It takes up space.  You might have room for the felt discs... you might not.
