So I am replaceing the clutch on my fathers '99 K1200RS and ahve hit a bit of a snag to say the least. To remove the trans you must removed the driveshaft housing (swingarm). The swingarm has a pivot pin screwed into eash side of the housing and these go inside the inner race of the swing arm bearings. See item #5.

Well they both were severly stuck in place. I managed to get the right side out but am at a loss on the left. Here is what I have done:
Broken Napa 3/8" drive 14mm socket
Broken Craftsman 3/8" drive 14mm socket
Broken Snap-on 3/8" breaker bar
Broken Craftsman 1/2" drive to 3/8" drive adapter
Broken chrome Matco 1/2" drive deep socket
Broken chrome Matco 1/2" drive shallow socket
Broken Matco 1/2" drive impact socket and in the process rounded the head of the bolt.
During this expedition in breaking I have used penetrating oil and heat to no avail. I have used my Matco 1/2" impact and am now at a 1/2" drive 24" long breaker bar with a fork tube as a cheater pipe (40"+ of leverage). I can get my breaker bar to bend a good 4 or 5 inches in the middle and that blasted pin will not come out. Finally I have welded a 30mm axle nut to the pin but keep breaking the welds.
I am serioulsy at my wits end. There is a housing on ebay and am serioulsy contemplating sawzalling mine in half. My next step is going to be to reweld, let sit over a day. Heat the tube and shoot some freon or the like on the bolt. If that doesn't do it I have no more thoughts.
Anyone have an idea?
