Petter Paz1 cracked flywheel

Hi all,
started to overhaul Petter Paz 1 and found today after cleaning that the flywheel has a crack appx 1" long from key way. Has anyone tried to repair / weld or is it best to replace. If replacement is reqd who has any!

Thanks in advance.

Just a thought, is the flywheel he same size as the Petter A1. Do you have dimensions and shaft size?

It's a more chunky design on the PAZ but the shaft size is the same at 1.5 inches.

Thanks all, I'll need to check shaft size. Forgot to check today when i was in workshop. Only just remembered to remove block from industrial cleaning tank! It's been in for three days! Needless to say it's very clean.
