Did I screw up these Honda C70 fork bushings?

Howdy--I'm nearly done refreshing the fork on my C70. I got a kit from DRATV kit, removed all the old parts, and put in the new parts. I pressed in the outer bushings and now the inner ones don't fit (I used a press, and they went straight in with a little force. It felt fine).

They would probably go in with pressure, but then the suspension wouldn't work very well.

Was I supposed to use heat on the suspension arms and get the interference fit to work with heat? I can't imagine I damaged them with the press, they went in really easily. The inner pieces also fit easily before I pressed the outer pieces in. Ugh.

The bike!


The suspension arms, still on the bike


That stupid press that I thought I was so lucky to find.


The old, worn bushings.


Success! (or so I thought)


It looks so easy. Look how loose the tolerances are.


The mess I'm in now.

I expect the fit of the inner bushing within the outer is very close, so
as to not have play or looseness. You say the two fit together ok before
installation of the outer bushing..? Then perhaps the pressing procedure
upset the edge of the outer bushing a bit. It would take very little to do so.
So, look carefully at the outer bushing edges(s), and remove any imperfections....

Thanks for the reply. Pressing didn't mess up the edges though. The rims of the outer bushings have a ~0.5mm chamfer, and it isn't deformed or damaged or nicked all the way around, either on the inside or outside edge of the chamfer.

It's like the outer bushings are either squished in 0.001", or are slightly ovalized.

Woe!

If you are looking for a simple and cheap fix, just use a round file and lightly remove enough of the inside that you get your clearance. As long as you use your brain and your eyes you'll do fine.

Or else you can buy an adjustable reamer to get your clearance:

Better yet, go to an automotive machine shop and have them hone the bushings on their Sunnen honing machine. Bring a pin so they can check the fit. It should only take a few minutes.
