Re: Help.. Broken Bottom engine casing.
I'm not a big fan of JB Weld but many members swear by the stuff. For this repair it might work just fine. The trick is to get the area clean, free from any oil or grease and try building up the area where the piece is missing. You could try an old method whereby you use tape to back up the hole then fill it with the repair material of your choice. You'll need to smooth the edge where the clutch cover meets the case making it fit snuggly to seal out dirt. Wax paper between the case and cover can be used to keep the cover from being 'glued' to the case while you apply the epoxy. In all honesty the aluminum foil tape idea might work too. The idea being to keep the clutch from getting too dirty.
There is a point that is being overlooked here and that is the loss of the woodruff (half-moon) key. Was it missing when you removed the small gear? Is the crankshaft/gear/key in good shape or is anything damaged. That key is an important item and must be installed correctly during reassembly. Good luck. Keep us posted on your progress.
