I would probably groove it and weld it to get you going but then source another one for piece of mind.

Re: Weld it or replace it?

It seems half of the used ones out there have a crack in it already somewhere or another

I think a weld could hold up long term, depending on the quality of weld? good idea to make sure it gets grooved first though......wonder if welding will distort it too much though?

anybody else?

If you try to weld it and it fails again?

If you don't try, you'll never know. But it certainly looks like its worth a go by someone who knows what they are doing.

haha that was the part i was scared of.......

although who knows how long its been broken for this much, i wouldnt have noticed it if i handt had the swinger off for powder coating and was putting a peice of instructional tape around that very spot ......

I think ill give it a go, there should be somebody who is a good tig welder around here........

If your worried about distortion you could fit a bush inside and clamp the out side before you prep and weld. A decent fabricator would do this anyway if your taking it somewhere to get done. Leave it clamped until it is fully cooled. Im thinking welding it should suffice as it's probably been cracked for awhile anyway! Im guessing the drive from the rear wheel would be trying to push it into the bike more than pulling it away. Then again it is cracked so i could be wrong there, ha ha!

Re: Weld it or replace it?

I know you said you are powder coating your swingarm. I think that is ok, but check out if it changes the surface tension of aluminum. I read an NTSB report from a helicopter crash one time where a control rod had broken in flight. The cause of the accident was the annodization of the control rod. Evidently, the helicopter was a pretty custom show chopper, and the owner had all the control rods annodized. the annodization actually changes something in the aluminum's surface structure and caused the control rod to lose about half its strength. Considering the abuse a swingarm takes, it might be worth knowing if that will affect the aluminum.

Re: Weld it or replace it?

also i was on the fence about powder coating the swinger anyway........i always thought maybe i could polish it?.........well it missed the bus and now its getting polished for sure, even if i gotta buy a new one later,
