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.


Pouring transmission fluid into the intake and letting it soak in for a
spell will oftentimes free them up.

Has the tool been lubricated in use? Air tool oil is preferred - ATF
works in a pinch,


Others might disagree.

Disagree with what? That Air Tool oil is preferred, or that ATF is an
acceptable substitute?


That heavy detergent lightweight mineral based anti-wear hydraulic fluid
which has been marketed as "air tool oil" and sold at a hugely inflated
price is any more effective than ATF.



but MMO is a better alternative (all I used in my air tools for YEARS.)


Could be a better alternative, then again, could be pure hype....

And what's your point??


My point was that others certainly DO disagree.

What are you, ****ing retarded?



But I've been using transmission fluid in my air tools for for about 35
years now and have had a problem exactly once, with a cheap Chinese POS
that came as part of a package deal along with a backup compressor that I
had bought at Sears.


And how hard do you use it?


Oftentimes, my die grinders are used 8 hours per day, for weeks at a time.

I think the one I mentioned above lasted a couple days was all.

On the other hand, my Dotco right andle grinder is going 35 years old and
has had only a single vane replacement.


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.


Kind of makes me wonder why it keeps breaking.....


OK jerk.


Forget to take your meds this morning did you ?

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.


Whatever you do, DON'T put red dye in your air-tool-oil...

Back then any part for a CP734 was available
off of just about any good tool jobber's truck.
