Larger bolt underhead area (replace tiny allenhead bolts with integral washer hex head) and a steel backing (NA washer ring, in my case) fixed it for me. No need to mess with larger dia bolts and such, in my case...
A word of warning. The 6x15mm bolts provided by Vishnu are a full 8mm too short. They barely bite into the pulley boss, so there's no doubt that they'd snap off.

I'm now up and running again, with 8x20mm hardware. The next jump up was 8x25mm, so after Rev Greg cuts me a washer-ring, that's what I'll run.

Thanks Greg--but I can either come to you or send you a drawing and/or spare parts. I don't want to ask you to come to me for a favor.
