250-500cc 2009 WR300 cracked swingarm. What should I do?

Blew the shock seal on Labor Day. Shock is currently at suspension guru getting rebuilt. I'm cleaning up the swingarm for re-assembly and I find this. What should I do? Think it can be welded? Or do I need a new swingarm?

Ouch.

don't think that's the answer he was looking for Tim your the welder that fixable?

Not pretty, is it?

bet this would work and you could turn around and sell linkage for 100

I would say "Yes" it is possible. How would I go about it?

If a new billet 6061 aluminum alloy bushing was turned on a lathe that would accept the swingarms drive side Torrington needle bearings. Maybe a bit thicker wall and a bit larger outside diameter for that side only this time. Then the cracked end bushing was carefully removed on a milling machine to fishmouth the end of the swingarm tube to accept the new end, welds cut back and if it was prepped for welding correctly. Then it was held down and realigned in a fixture properly with the pivot shaft all the way through for instance. (The jig or fixture could be made up in advance before cutting the swingarm up for the actual repair).

Yes it is repairable. It could be costly though and only one chance to get it right.

Meanwhile, I would be looking for a good used one to replace it with for a spare.

Is this common to the WR250 and WR300s?

Has anyone else seen this happen before?

What I'd really like to know, is what exactly caused this?

Isn't the listing for the earlier swingarm on ebay for a rightside drive chain and yours is a leftside drive? Or am I seeing this wrong. I'm not too familiar with the WR250s and 300s.

I vote for a new swingarm.

be careful of the year as linkage changes do affect the design
look for same or similar years

Do you know which model years are the same as the 2009 WR300?

I bet any year since 2002 WR/CR250/300 will fit.

If you are close you can try my spare swingarm.

this happens fairly often on the 85-88 husqys..i have tig welded them and put them back into service. bike has been running a year without a crack. not an ideal solution tho. best to find a new one. i thought a dry bearing was what caused it but yours looks to have decent bearings

Appreciate the offer, but I am in Hawaii.
