Been there and done that before a long time ago. Chase it with a bottom tap with the correct thread pitch. Problem solved.

I'm hoping the same. Measuring everything out it looks like the threads on the bolt stop right about where it would bottom out in the crankshaft.

If I wanted to buy a tap instead of making one, what size and thread pitch would it be? I've searched everywhere, called the dealer, local Indy shop and still no answer. The closest I could find on the internet was m16x1.5 but it was never confirmed.

If you can’t find any info about it, bring the bolt to your local hardware store and find a nut that threads on to determine the thread pitch.

Thanks. I just went to 3 different ones this morning with no luck :facepalm:

Did you try Ace hardware? They've been real helpful helping me figure out thread pitch in the past. Just for the hell of it I called Z1 and they were no help. They said they didn't know.

Lol, that's funny because I called Z1 first thing this morning. I also called SOHO which is local to me and they were no help either. I'll give ACE a try. Thanks!

No wonder Z1 just blew me off. You had already called and ask the same question :rofl2:

If you have a set of digital calipers u might be able to measure the thread size/pitch yourself.

I admit, I'm obsessing about this a bit so bear with me. Looking at everything again, it occurred to me that even with the pulley on, the face of the crank nozzle is flush to where the pulley bolt meets anyway. It's the flange on the bolt head that grabs the pulley and keeps it snug. It doesn't sandwich the pulley between the bolt head and the crankshaft (hope that makes sense). That being said, when the bolt is installed even with the motor fully dressed it's the same as if the pulley isn't there, either way the bolt head rests against the crank nozzle. I have a feeling once the new bolt shows up it will thread right in with no problems.

Applying the dimple won't screw up the threads in the hole or be the cause of cross threading etc? Curious as to why not high temp. thread locker. :tiphat:

Using just a c*nt hairs worth of blue loctite will work just fine.

Dimpling the edge of the screw won't damage the threads. Too far away. You don't touch the threads.

If you can get the hole completely free of oil and dry. Blue locktite is better

Use a blow gun while hooked up to shop air and hold the nozzle to each hole and blow them out one by one. Then I'd spray them out with brake clean. Then, you could blow them out again and wait for each hole to dry before installing the new gaskets.

Brake clean should also work if you don't have access to shop air.
