Default Impact wrench (air) repair

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, 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.
