Primary bolt turning crank before tightening up against clutch

[milehighassassin]

I am trying to get my primary back on and I cannot keep the bolt from turning the crank before it tightens up against the clutch.

Threads on the bolt look fine. While it was hard to come off, it came off like every other clutch I have pulled. I thought maybe there was something blocking the threads, so I've sprayed brake clean in there and taken an air hose to blow it out. Also tried some dry graph on the bolt, still nothing. I can start it threading on it's own and no clutch on the crank, it hits a point and gets hard to turn.

Any ideas?

I don't really want to force it and grab the impact to twist it on there.

Thoughts?

TIA

Bolt

Sounds like the threads are messed up a little. Take the bolt to the bolt supply and get a bottoming tap to match. Chase the threads in the crank and it should fix your problem.

I cleaned the taper of the crank and the matching side on the clutch with a light sand and brake clean.

The problem is that I tried to put the bolt in with no clutch, and it would just spin the crank at one point.

I finally put the clutch on pushing it in kinda hard to seat it on the crank. With that I was able to some what hold the clutch which in turn held the crank. The bolt slid past that one spot and seemed fine. I think there might have been a little something in there. While I had the clutch off I installed the Holz vent up there to make cutting and drilling easier. Slight chance I got a little something inside there (plastic maybe).

The thought didn't even cross my mind that I should have covered the bolt hole going into the crank when doing something like that. Maybe someone else will read this and learn something from it. No damage to me but it was a bit of a pain for something that should be simple.
