Plastic Part Threaded into Al: Grease?

I am reassembling some el-cheapo quill pedals and the bearing surfaces
are embedded in a plastic sleeve that screws into the pedal body.

viz: http://tinyurl.com/o3cfny8

Should I grease those threads? Normally I wouldn't think twice, but
with the rotational nature of pedals and the downside of the things
backing out in use...

We don't. Many similar models have threadlock on those
threads but 'bearing assembly unscrew from pedal' is rare at
any rate.

Since you have the professional answer already, I hope you won't think I'm hijacking your thread, Pete. I'm interested in what you consider el-cheapo for pedals. The context is that us Europeans can only look with envy on the very low prices you Americans pay for components.

$20-30 as in http://tinyurl.com/mqxcqck

Those are not an exact match but they look superficially very similar.

The English to photo translation takes a moment but here's the nitty:

https://www.google.com/#q=plastic+threadlocker

time passes, chemistry macrhes on, better living is said.

Marched to the point where blue Loctite may surface and not partially melt the marched on plastic or whatever it is..

bearing surfaces embedded in plastic would be greased with silicone grease either Wood's if he temps are HOT of Finish Line silicone if not so HOT. Wood's is stickier more energy absorbant, FL is slipperier, more fluid at room temps. I assume Wood's is still around.

Most plastic threaded thingees are designed or not designed (?) with variable thread percentages across the entire mating surface.

These threads both give if near zero gap or fill if less than 70% gap...in total adding all the +/- thread %...the assembley secures..

AT LEAST ONCE....but maybe twice as TMO. or more or forever with Cateye and Porsche.

Soooooo, to make a shot story interminable as Europeans are wont....

pill n wobble the fitting see what it does as it threads in..

secure ? cool howhowhowhowever....if secure then the fitting needs lubricants as that plastic locktite or silicone grease ifn yawl wanna tale a chance on turnout. Cresswell checks the components at intervals ? then that suggests silicone....long distance riding in the boonies suggests the plastic locktite....which doesn't usually 'go bad' ifn the tube is kept cool.

I'd buy the plastic lock out of curiosity

eyeeyyahhhahha there's a market battle with the usual...

Threadlocker is a general purpose product....yeah yeah yeah big deal...

Aggressive formula requires no primer to cure. Prevents ... jock rash tooth decay and concrete floor finishes....leading to a rash of hole cartoons...

CAUTION: Threadlocker can significantly weaken plastic, causing parts failure....not a big cellar...see above.

A high strength anaerobic gel threadlocker designed to permanently lock fasteners up to 1 .....or for 30 days

.... Please note, this item is not returnable...note that wudja ? here's the B1


Threadlocker is a general purpose product - not good for anything

I am in the process of trying to send a GoPro Hero cam go a guy in
Germany.

Straight-up, unsolicited gift.

I *thought* I was going to just click a few boxes on Amazon.com, fill in
the shipping address and forget about it. Turns out that Amazon
declines to ship that item to Germany.... and I am beginning to
understand why.

Such a mess... Right now I see at least 19% VAT tax and/or up to 50%
"Gift" tax - the worst part being that I currently have no clue what he
will get hit with on his end.

A little bit like giving somebody a puppy and calling it a "Gift".

Where is The Global Marketplace when I need it? .... -)
