what oil for impact wrench hammercase?

[gofastman]

I tried air tool oil but got a lot of metal particles in a very short period of time, I think I need something that is better suited to EP conditions. Right now I'm using Amsoil Severe Gear 75w140 and I think it may be robbing a bit of power from the gun.
anyone have any advice to lend?

I've been using Marvel Air tool oil in my impact wrench and it seems to work fine.

non detergent SAE30?

gofastman,

Can you give us more details? I would have thought that air tool oil would work. Which air tool oil?

the MATCO guy gave me a bottle of Marvel air tool oil with every air tool i bought from him, i have a nice little collection now.

I use whatever is handy. 20w-50 in the squirt can, wd40, etc.

I not talking about the oil you run through the air fitting, I'm talking about the stuff that goes in the hammer case.

 

[nfs480]

Yeah, I use air oil in the hammer case too.

I was actually just pondering the same thing. I thought that grease was the correct product in this case? But, what type of grease to use...? I used to work in a shop that had the small grease gun from the Mac dealer and I just used this maybe once a month without giving thought as to what type of grease was required.

I do what ksJoe does, whatever is handy. Right now it's Mobil 1 ATF, because I had an extra quart that I'd never use otherwise. I think ANY type of lubrication for air tools is going to give it a long long life. I know plenty of mechanics that don't filter or regulate their air supply, and don't put anything at all in their impact wrenches. Not the way I like to do it, but it works fine for them.

The instructions that came with my IR gun I just bought said to use 4cc of IR #50 grease in the zerk hole every 48 hrs of operation.

Some Impact tools use grease, my IR Titanium guns use a grease kit made by IR that contains a grease gun and very thin (I think #00) grease. Don't over grease your gun BTW, It will reduce torque output significantly, you only need about 4 squirts from one of those little grease guns every 48 consecutive hours of operation.

My AirCat tools have an oil bath system. It doesnt usually need regular maintenance but I needed to open up the gun for a repair.
