Hi

I have done this before, but cannot remember how.

I am trying to remove the bearings from the swingarm of my 1990 R80RT. I know I'll have to put drops of weld on the races to remove, but how do I actually get the bearings out? They certainly don't seem to want to pull out.

Swingarm is off to be power-coated. 5 x Scottish winters have done for it otherwise.

Thanks, Andy

Pry off the seals.
At that point, the bearings fall out.
Lay a bead of weld around the race, allow it to cool and it too will fall out.

Your question confuses me, so maybe I didn't answer your question. Weld doesn't come in drops.

Actually it can.
Spray arc.

Not to say one can buy a liter of weld.

A spray isn't a drop. The former is under pressure and the latter is powered by gravity.

Globular transfer mig welding drops molten metal on the weld pool. Its pretty ugly, lots of splatter.
Short circuit mig is used a lot.

Clearly globular transfer would transfer globs. Duane is talking drops; not dollops, blobs, sprays, spots, goobers, boogers, smidgens, bits, or . . . globs.

You let us know when they come up with dropular transfer mig welding.

Dropular transfer is when the molten puddle lands on your boot.

Spray arc isn't under pressure.
And they're droplets, driplets, tit- bits, morsels, weeny offerings.

Boogers that's so uncouth.

I welded out my swing arm bearings a couple of months ago.
Same technique as head stem bearings.

Wouldn't the ideal swingarm bearing weldout machine be a TIG welder? No messy transfer of metal in any of the aforementioned unsavory configurations. Doesn't mean you wouldn't have to be careful, but a bit of hum and you're done?

Can't see why it wouldn't work Ken. Perhaps a little safer as you say.
I don't have a tig.
It would be interesting to do a comparison to see if the addition of weld metal is necessary to aid in shrinking the shell.
