Here's a thread with pictures of damaged pin slots on the crankshaft:

I'm wondering if it's possible to weld the balancer to the crank if the pin slots are damaged. If the crank is shot anyway, it seems as though getting the pins roughly in place, and welding the balancer is worth attempting. Perhaps there is no room for a weld between the balancer and vibration dampner. Maybe the materials can't effectively be welded.
