Distributor Bolt question

[Divenut]

Hey folks,

Finally after 14 months, we got the Duster fired up! Talk about a great feeling. My wife and daughter heard them open headers and came running out to the garage. Hugs and high 5s followed ;)

Anyway, I noticed the timing was wandering around and I noticed the tightened bolt on acted stripped allowing the distributor to move. Pulled it out and threads feel off the bolt.

Not sure is this a unique bolt, looks close to an oil pan bolt, but they don't want to go in? The old one almost seems tapered. Is that the case?


Thank as always,
Pat

Pretty sure that bolt was way too long might have bottomed out in the hole and stripped the threads

Run a bottom tap and blow out the crap. I use an old header bolt.

That looks like a fender bolt

Yokes! Fender bolt?! Aaahhh the joy of finishing other peoples' projects.

OK thanks for the quick responses everyone. I'll see if I can find my chasers and clean the threads up.

Take care,
Pat

That is a tapered bolt as you observed and is not right for that spot. Somebody put in the wrong bolt. If it has stripped the threads out, then it's time for a Heli-coil insert.

I believe it should be a 5/16" x 18TPI bolt. And if you tap into the hole, IIRC it is blind and does not open below that flat area, but check; if it IS a through hole, be careful to not let chips get inside the engine.

Good for you on the fire-up!

That will be a course thread bolt/hole to chase correct?

Thanks again all!
