Picked up my impact wrench (1/2") and it stopped working. Pull the trigger and all you get is air out of the exhaust. No rotation.

Is this worth tearing into? Could something be gummed up, not letting air flow to wherever? I'm generally good at fixing things but I've never been inside an air tool.
All advise appreciated. BTW, the gun does not have that many hours on it. 9 years with maybe changing two or three sets of wheels per year.

Thanks,

Pouring transmission fluid into the intake and letting it soak in for a

Has the tool been lubricated in use? Air tool oil is preferred - ATF
works in a pinch, but MMO is a better alternative (all I used in my
air tools for YEARS.).

If soaking some MMO (Marvel Mystery Oil) doesn't free it up, take it
apart and clean and oil everything well and it should work. I've had
mine apart several times over the decades, and replaced broken hammers
and all kinds of parts. Back then any part for a CP734 was available
off of just about any good tool jobber's truck.

Back when the CP (Chicago Pneumatic) plant was still in Utica they
supplied "air tool oil" to the dealers and companies they sold through.
They would bring in bulk 55 gal drums and had a machine that then filled
whatever container the customer specified. The oil used was all the same
regardless as it was to CP spec. The bulk oil supplied came from the
Marvel Oil Company, and was SURPRISE : Marvel Mystery Oil. When they
were closing the place down I was still driving for a company that did
paint work for them and they were clearing stuff out by the dumpster
load. One of the items they were disposing of were cases of oil in old
sears logo containers. I remarked that it was a shame that it was
getting thrown out, went back got the paperwork for the stuff done and
came up to find the load off and the door closed. Hit the next delivery,
opened the door and found a PALLET with 20 cases of oil on it, in the
back !!!
I am still using that oil in the shop oilers.

OK jerk. That 734 was 20 years old when I bought it. It was used by a
race-team pit crew on CO2 for several years. Then I used it every day
- and I used it hard. I rebuilt it twice in 26 years. Plus replacing
one hammer unit that broke. And that was running 125-150 PSI line
pressure on farm equipment, trucks, industrial equipment AND cars.

That CP is still in my tool box - and it was made back in the fifties.

Ivan, I've a couple of air rattle guns & when they've done that I've just
squirted a load of wd-40 or similar into them and spun them by hand &
they've come good. Mine also sit idle for months at a time.

I would fix it, even though I have not yet been in an air tool
either. Just a matter of time until I get the excuse. :-)

Do you squirt air tool oil into the fitting just before
connecting up the air *every* time?

Is your air dry, or full of water? If the latter, it will rust
which could be your problem.

What happens if you switch between forward and reverse a few
times? Does that break it free (with addition of oil, of course).

Good Luck,
DoN.

With that little bit of work, it's probably something dried up and stuck.
I'd try with the air, and pull the trigger. And then do some percussive
maintenance (whack it with a brass hammer) to see if you can get the stuck
part to loosen up.

They typically have an oil hole, but it's likely beyond that.

Ivan, it's usually gumming of the old oil and is usually a quick
repair. I like to relube with Marvel Mystery Oil for reassembly.

Get the manual, note the parts in the exploded view for reference, and
note the way the vanes sit in the cylinder. One edge will usually be
more rounded. Soak the metal parts in lacquer thinner for half an
hour, brush them with it using a nylon brush and let them dry. Relube
and reassemble. All done!

Check the condition of the vanes, and the bearings.

The air tools I used to rebuild would get cupped on one side (presumably
they'd get cupped on both if you go both ways equally -- the impact
wrenches were used in manufacturing, so they mostly drove one way, and
the grinders -- well, they always go one way). If the vanes aren't nice
and flat where they're obviously supposed to be flat get a set of vanes
and replace.

Mostly I spent my time disassembling, cleaning, replacing vanes if
necessary, and reassambling. But if you spin the bearings and get grindy
noises instead of a smooth "whizzzzzz" then replace them, too.

I'd tell you to make sure the impact head is in good shape, too, but it
doesn't sound like that's your problem, and we never got that far into
the tools anyway so I have no experience.

We use impacts in production and have in-line oilers filled with air
tool oil or trany fluid. Just a tiny amount will keep even the cheap
impacts running. A good impact will run forever if kept lubed. Don't
crack it open until you try lube in the air input. Let it sit aftyer a
good dosing if necessary.

your compressor may need to be drained of condensation. Everytime you
start using your air tool, put a a few drops of air tool oil into the
air fitting hole. Don't do this with a DA sander.

The admonition NOT to oil a DA is dependent on what your usage of it
will be AND how well it is built.

Usage wise - If you're doing prep for paint type work with it the oil
can mist out onto the item and get embedded in the material.
Oil under filler/primer/paint is NOT a good thing. If your using it for
other work then oil away.
However you can oil a DA and still use it for final finish work. Add a
few drops of oil to the inlet, then wrap a rag around the air outlet and
run it till oil stops coming out.
If you have one of the good DAs it will likely have a filtered outlet
just for this situation. In that case you remove the filter, oil the gun
and run it. Wipe off the oil and install the filter.

I have a couple of guns in the shop right now that seem to have vane
issues when at low power. Will probably pull them apart and see if it's
sticking vanes or poor finish on the barrels. One is a newer IR and the
other is a IR knockoff that someone gave me because they got it for a
gift, but don't have air in the shop!

Because if you put oil in immediately before use, you will spray oil
film on the surface of your work.
You can oil the DA, but run it without being anywhere near your sanding
surface, and make sure it is no longer spitting any out when you use it.

I tried all the methods on the group. First I turned the rachet about 10 times in both directions, then I put some MMO into the air port. It fired up on the first try and runs great. This tool has never been used so I guess it was just stuck from being idle. Great posts saved me a trip to the supplier to only have them do exactly what I did. Thanks to everyone who answered Ivan.
