My TB grinds at the small bearings in the ends of the butterfly valve.. What grease should I use in there to keep it from grinding? One that also won't hinder performance.

JPXJMOAB

Anyone? I'd like to get this done. Engine oil maybe?

Have you taken the air tube off and actually cleaned the TB? It is a good idea, mine was terrible, a lot of carbon buildup. Kinda sticky after I cleaned it but I shot all the joint areas on the outside with WD-40, to get the crap out and it seems good meow. I'd be curious to know if they should be lubed, and what to use...

JPXJMOAB

yes lol it's freshly bored to 62mm and 100% clean..

Eisenschwein

100% clean, eh? hmmm... guess there is such thing as too clean. haahaa See, I stopped at 96% clean and mine doesn't grind.

JPXJMOAB

lol I meant 100% clean as in no carbon at all because it was bead blasted

Eisenschwein

I know, I was being obtuse.

Is there a chance there was a burr edge around the butterfly pin holes, left from the bore?

Maybe send it back and get one that is not damaged?

JPXJMOAB

it's not damaged, my original TB did the same thing, I found online it's supposedly that the small bearings are dry.. ?

Probably bushings, not bearings.

Tri-Flow?

JPXJMOAB

is tri flow like a lubricant I can pick up from a parts store? Never heard of it.

Eisenschwein

It is usually used on muffler bearings.

Just use a drop of engine oil. (off the dipstick if you like)

Eisenschwein

I prefer Maiden Oil myself... great beard lube.
