Air Impact Wrench

…I bet its also a 1 11/16”…

Yes, the blade bolts use a 1 11/16” socket… and somewhere I’ve written down the socket for the blade holder socket…

Craftsman store price about ~ $14.

Richard… here’s my “manual torque gun”… would ya say up to ~~ about 1575 ft/lbs… give or take with “one me”… /forums/images/graemlins/blush.gif

I,also have a IR2131A impact wrench. Purchased 8mos. ago
from Northern Tool, I have used it many times with nothing
but praise for it's performance.It is rated at 600f#in rev.and
450f#max in forward(at 90psi). My gun is the short anvil type
which makes for a compact size.For it's size it really packs a
punch.I use,and mfg. recom. a 3/8 Id hose for best performan
ce. The only limitation I have,is the borderline performance
of my air-comp. My a/c is an old sears 1hp-12gal unit,rated
at6.4cfm@40psi,5.4cfm@90psi.To sum up,for best performance,you need a good cfm,(to match mfg. spec)a
large hose (at least 3/8),a strong I/R(high f#) capable to do
the job at hand.

I just received my IR2131. The instructions say to install an inline oilier a moisture trap. I have a moisture trap but no oilier on my compressor. My tool will not receive heavy usage so is it safe to put a few drops of oil in the tool before each use rather than installing an oilier?

John, I think only shops where the tool is used nearly all day bother to install an automatic oiler. Everyone else just squirts a little oil into the air intake before hooking up the air hose. And I think most people do it before using it, and sometimes rarely even then, but if you want maximum life from it, give it a shot of oil, then just a brief burst of air to circulate the oil when you're through, before putting it away. Now a half teaspoon of oil is probably adequate; however, you cannot hurt it with too much oil; the surplus is simply blown out the exhaust.

Bird,

Is there any air tool that could be harmed by too much oil?

( Is there any air tool that could be harmed by too much oil? )

Not to my knowledge. The air tool oil that goes into the air intake will simply run into the air motor (most of which are rotary motors although there are some reciprocating piston air motors in things like inline sanders, saws, etc) so it will either run, or be blown, out the exhaust. On the tools, like impact wrenches, that have motor oil or grease in the front end, an excess of those lubricants will not likely harm the tool, but will reduce power until the surplus works its way out. Although I guess it is at least theoretically possible to damage an oil seal in the front end. But air tool oil in the air intake; no way an excess can hurt anything on any tool I know about.

Now of course, you have to realize that I was just working on air tools as a part time job I enjoyed for two years and didn't want a lot of business, so I only worked on a little over a thousand of them (983 invoices plus what I did for friends, family, neighbors, and myself without writing up an invoice) so there are lots of air tools out there that I've not had any experience with.

Thanks, Bird. When I got my finish nailer, I got yelled at by a relative for putting more than two drops of oil down the air intake. Supposed to gum up the gun. Never could figure it out. If three drops will gum it up, seems like two would also.
