I would not but yer gonna get lots of thoughts on it.Stripped head bolt threads in motor. Can you fill the hole with j b drill and tap
I think, I'm not sure but I seem to remember sets of helicoils or threaded inserts with taps at Harbor Freight. I know I've seen them at McMaster-Carr.
This was a interesting point I wounder how many of these motors might just simply need taped out deeper before the damage is done.DaveC said:What's going on is the Chinese don't tap the holes to the bottom. Then there is less of the threads engaged to prevent pull-out. Also the acorn nut bottoms out and the stud starts to thread into the block and it can't due to the hole not being tapped so the stud doesn't thread, it just pulls out.
Threading the stud holes is one of the things on the "what to do before you install your motor" thread. One of the first pieces of advice is get rid of the acorn nuts and use real ones from a hardware store or a nut and bolt place.
