WD-40 will dissolve grease. Seems like you would want that grease in there for extra lube for the gears.

Does any one have any proof of this air tools having grease p in them I have never herd of this before and am very curious about it

We don't, at least not in the motor area.

The question with WD-40 as a lubricant (or any other oil for that matter) is if it is compatible with the plastic/resin used in the vanes. For the most part- if you don't saturate the motor for a prolonged time it really shouldn't matter, but it could lead to gumming up the cylinder and premature vane wear.

I'm sure thats why (aside from legal and profit reasons) IR only recommends its own brand of air tool oil.

WD40 really is not a lubricant so much as it is a solvent, it is in fact a poor lubricant, and regular use as an air tool lube will ruin the tool! Clean all the parts with a good solvent then lube them with air tool oil before reassembly, after that just use the air tool lube as directed by the manufacturer. Regular air tool oil is all you need unless the manufacturer specifically recommends grease on any of the parts.

WD40 is one of the worse things you can put in an air tool. After the carrier solvent has evaporated what is left behind is a yellow goo. Marvel Air Tool oil is made for air tools and is the ONLY thing I ever used on all my air tools. A few drops in the whip hose every morning before starting work and your good to go. Once a week I would liberally run some into the the air tool and let it sit over the weekend. Monday morning I would hook up the air tool and run it unloaded for several seconds to remove any residual. As noted, air ratchets never need grease in the geared sections, a complete waste of time IMHO.

Marvel, IMO, is THE oil to use! That heavy dose once a week in addition to a few drops every day will keep the tool flushed out and clean inside and doing that more often will not hurt a thing.
