there was a post here a few days ago about an oil pan, someone posted up an epoxy repair kit, seems like a good choice for your issue. I would post a link but that is above my pay grade.

 

Pooh Bah thanks. ''Twas an Excellent tip.
So I go today to auto zone and ask for a 1/4 20 time sert kit. Deer in the headlights look he gives me....ut oh I say to myself.

I say "you know...a thread insert kit for stripped threads" ...he lights up and dashes from behind the register, down an isle, back up behind the register in about 6 seconds! He has a helicoil kit.......

I didn't even ask again about the time sert kit. His eyes told me just go with the helicoil kit. I figured someone was looking out for me to save me 50 bucks so what the hell. Helicoil it was.

I came home, watched a few you tube installs and in about 15 minutes I was done. Derby cover reinstalled and all screws torqued to 108 inch lbs. mission accomplished. Thank you and all very much.

 

True that! Thanks lp

 

Were primary covers sheet metal back in the 50's?

 

Yes, Knuckles and Pans were stamped steel covers. (And everything else before that as far as I know.)

 

After watching the video I noticed that he drilled THROUGH those blind holes.

Probably a new dude who didn`t know much, but `glad you got it fixed.

 

Helicoil should work.

 

Yup I'm embarrassed. Been riding 30 years but never really did any real maintenance. Lots of component swaps. Motor work went to the dealer...still does. Lol....When I stripped out this bolt hole i damn near had a panic attack.
Thanks to u guys I learned something else.

 

Lol! Was about to suggest bubblegum. Worked on old panheads.

 

Nice job. You did it right. I was thinking bigger screw.
