AntiSieze on a Press [Shrink] Fit

It seems like an oxymoron, but when I pulled the flywheel on that 22-36, I thought maybe anti-sieze would be a good idea for assembly [not that I suspect it will ever be off again, but Murphys law dictates I screw up somewhere and have to, if I assume as much].

When I got it off, it almost looks like the factory or last person in there had the same idea. A rather silvery grease residue sure looks like anti-seize to me.

The bearings had a yellowish grease; on those I went with motor oil for assembly. Like I'm planning for the flywheel, I took them about to about 150F or so (just to the point I coudn't handle them bare hands] for assembly; did the same with the rear bearing carrier to insert the bearing. The aspect ratio on that rear bearing isn't too friendy for staying straight while you push it it on, but a little help from a multi-purpose-impact-pursuation tool [and a purple finger nail :oops: ]: firm against the end.

Funny thing is: I think I posted this as a tangent in another thread I started, and, in keeping with my habit of forgetting the answers to my own tangents, now have to ask again! :? :lol:
 
I'm not sure you asked a question. But my answer is that clean properly aligned (possibly temperature modified) pressfit needs no lube of any kind, and might not be as firm if it had some put on. JimN

Yep, that was the question I had; Thanks!

I like the stuff, but with the intertia that flywheel has I don't want to compromise the holding force either. Sure looked like it had it before though, and that thing fought hard the whole way off; so still half temped; however your comments confirm there is good reason not too as well.
 
I "never-sieze", "anti-sieze", EVERYTHING! I have never had adverse results. Most say to run lug nuts dry, I slather the no-sieze compound on them too... Never had a wheel fall off... Am I right, who knows.

If ya really have a press fit, I doubht that some lube will make any difference on the retention force. I worked as a toolmaker, put in 1000's of dowel pins, press fit. I always lubed them. But maybe I am not understanding the mechanics - the dowels are usually for location or alignment.
 
So do I ,buy the stuff by the case. I put it on lug nuts, manifold bolts and anything thats in a corrosive environment. Worked in a power house for several years, we used white lead on all press fits, don't know if you can still buy it or not,I use Fel-pro or Never- seeze myself. never gaulded one yet.
