I have used LPS-2 for pulleys, hinges, etc. for yrs. Is this as good as any or should I be using LPS-3 ?

I never use lubercants at all.

(But if you're asking about oil to lubricate bearings and pulleys... the LPS-2 is what you're probably thinking about, and is an acceptable general purpose. LPS-1 is a light-weight penetrating type, and LPS-3 is a waxy protective/preservative.)

I was recommended ACF-50 a while ago and have been using it ever since. I use it on bearings, pulley, etc and have had good results!

What the hell, George , If Frank likes "lubercants" let him use 'em.

They cant lubercate.

Frank,
George is just to damn fussy. I'll bet you been using lubercants for all these years and they been workin' jus' fine, right?

I like ACF-50 and Corrosion X in almost every application one might use a LPS-1 type lube.

The packaging on my NOS Ralmark pulleys states that they are lubed with MIL-PRF-81322 grease. Greases that meet this spec include Aeroshell Grease 22 and Mobilgrease 28. McFarlane Aviation sells pulley oil and needles to apply it. My question is how to adequately lube the roller bearings in the flap and aileron bellcranks. The flap handle pivot is another spot that is difficult to properly lube. Seems to me Cessna should have installed grease zerks on these various shafts.

Never did hear her recommendation (but I've heard molybdenum disulfide is what should be used for sliding loads.)

This is what I get for doing a post without my glasses "LUBRICANT" You know, that slick stuff

LPS-3 is not a "lubricant," its a protector. It can be used to coat cables and metal work against corrosion . plus it dries to a waxy finish.Its very good in a salt environment. But must be reapplied every 12 months as it dries out.

Don't know about the Ralmark pulleys... but I suspec the 81322 greas is what they left the factory with and that Light Gen. Purpose oil is all those items need for on-going lube. (Also, keep in mind that Cessna's Service Manual approves any "quality" products to substitute for the mil-spec lubes.) I use an aerosol light machine oil in aerosols (LPS-2 is fine) or 3-in-1 oil which comes with long needle appicators. A good gun oil will work fine as well, and they can be found in needle and nozzle appicators.
Too much oil can be as harmful as too little because if you get it everywhere it attracts dirt and dust which can/does wear bearings and mechanisms. Good old-fashioned trigger type oilers also work just fine, but I"ll bet you end up with a can of LPS-2 or equivalent.
