Top yoke disassembly

Diablouph · Apr 15, 2010

Need help.

'73 850 top yoke. I want to take the shaft off to strip and paint the yoke. I think I see threads on the top of the shaft in the hole. Before I do anything rash, do I :

Unscrew, beat out, heat, and beat out, press out, heat and press out, or try to figure out a way to clean, sand, and paint it with the shaft in?

Appreciate any help.

Having done this several times, not worth removing it. It can be to harmed in removal it or misaligned it when refitting. Best to leave the shaft as is and clean up around it, mask off and paint. Note that there is a domed black rubber bung that fits into the shaft top. Roll up some paper and stick it in the bar and fork tube clamp holes, keeps paint out and lets the screws fit properly. The yokes will look fine once painted.

I just masked the shaft and it was fine. Any particular reason you want to separate them?

I absolutely have a reason for wanting to separate the shaft from the yoke. I’M LAZY.

I figured the best way was to mask, but I had to ask.

Thanks for the help.

The lazy approach (and I should know) is to not do more work than necessary. :mrgreen:

I'm a bit lazy but usually do way more work than is required. I must be going about things the wrong way.

Some sort of aluminum. I used it to paint my Bultaco frames. It looks great. Maybe not original but it looks nice. And you can touch it up unlike powdercoat.

Very Nice ! !

Gday all, Ive painted my yokes using VHT brake caliper paint. Having the ceramic element in it gives a beautiful gloss like powder coating finish when baked. Used it on my barrels too, mmmm... very happy!

I bet that's more durable than the paint I'm using.

Thanks for the help, I decided to just tape off and paint.

I still am courious though, is the shaft pressed in or screwed in?

Swoosh, the reason I asked what color it was is because it looked like a lite blue in the first picture you had. Now I see what it realy looks like and it looks great. I wish I did not have mine powder coated. I like yours better and without the saw dust.

How far are you away from finishing the bike? My frame is done, front end on, trans done and mounted, motor getting some work done.

The blue was the primer. It's actually grey but I didn't color correct.

About this far. I'm waiting for some wheel parts. Then I need to buy some things like coils, regulator, belt drive, chain... Then build the wiring harness. Then then it should start. At least that's the theory.
