Primary cover bolts
Don't know if this is the right section or not but i am going to ask. I am in the process of putting a new screamin eagle compensator and hayden chain tensioner on my bike. It is a 2007 Ultra Classic with a 103 kit. I was taking off the primary this morning. Naturally all the bolts came out ok except one and naturally it was one of the long ones. I started backing it out and it was like it started freezing up and getting harder to turn. I didn't know exactly what to do so I kept going in and out a little at the time and luckily I finally got it out. Surprisingly when I got it out the bolt looked fine. There was no aluminum like the threads were messed up or anything on the bolt. Actually all of the bolts seemed tight to me. It wasn't like you loosen it up a little then unscrew it with your fingers. It was almost like the bolt is too tight for the hole.
My question is when I go to put them back in should or can I use Never Sieze or something on them to keep them from freezing up and go in easier. Messing up one of the short bolts would be bad enough and i surely don't want to pull the inner primary. Any advice would be appreciated. Thanks

I love anti seize. Use on derby. You need to reduce tq. I haven't used on primary cover.
I'd blast some air and brake clean in. Than try threading bolt to see how it feels. If feels ok, I'd probably forget about it. But curious if others have stories. I supose new bolt wouldn't hurt. May e try and dental pick inside.
I most admit this would a sphincter puckerer.

Tell me about the pucker deal. I do not want to pull the inner primary. I may try the brake clean and air thing. I think the bottle of air to clean a computer key board would work as far as blowing it out. The last time the primary was taken off was at the Harley shop. Don't have any idea if they were torqued or not. Thanks for the ideas. I don't see what anzi sieze would hurt.
I do have a VW trike and I was told to not use Anit Sieze on the studs for the exhaust. The heads on it are aluminum. Didn't know if that would apply to this.

You don't need to pull primary. The bolts don t go through so nothing to gain.
Big thing for me, would be how it hand threads back in. If still bad may need to chase threads, which I have never done. Spray and blow, see how how it feels.

I would chase the threads but you can't get to them. It is the long bolt that goes through the inner primary. I would have to pull the primary which I am trying to avoid.
I am trying to find out about anti sieze. I think there is more than one kind. For different types of metal. Any information appreciated.

Did it look like the bolt had an excessive amount of Loctite on it? I had this happen once and just cleaned off all the Loctite and it went back in fine. It looked as though someone had used a whole tube of Loctite on one.bolt.

I would guess the there's a bit of corrosion in the threads because the primary cover doesn't get pulled very often, if at all. What I would do is squirt a bit of penetrating oil in the holes and let it soak for an hour or two before blowing it out with compressed air. I keep Liquid Wrench, PB Blaster and Kroil on the shelf.

what normally happens is a galvanic reaction between the steel bolt and the aluminum case. I would consider replacing all the bolts (a fastener supply house or industrial supply store are good sources) with stainless steel bolts. I would take one of the "good" old bolts and run them into every hole to make sure the go in and out freely. Consider a dab of anti-seize when installing new bolts. And a quick check on the torque/snugness of these should be part of your service routine.
