Thanks for the replies. My question was prompted after experiencing a similar catastophy to Dave’s. A screw came out and found its way down a tranfer port into the crankcase, the conrod eye then punched it through the front of the case leaving a hole about 1″ by 1/2″ ,also, a hairline crack in the piston skirt.
I am now considering my options for repairing the damage. A hole would have to be cut in the outer crankcase to access the damaged area for welding. Or, I could fill with steel reinforced epoxy putty accessed via the flywheel well.
Any advice would be welcome.
Also, the best source for a replacement piston please.
Roy
