Pneumatic motor stalls on start
Pneumatic motor stalls on start
(OP)
I have a small 0.33 hp Gast air motor. I've uncoupled it from the pump so I could work on it.
if I start the air to the motor, it just blows through. but if i jog the shaft just a little, it picks up and will start working. Once I stop the motor, again same problem, air just blows through.
Is it possible to fix this thing?

Try flushing it with a solvent/oil mix, or Marvel Mystery Oil straight.
If that doesn't work, you may have to disassemble it to see what's going on.

Thanks. I used some ethanol to dry out any water in the veins. Then purged some air through it, and let it dry totally. And then just kept dosing large amounts of air lube oil with a syringe and manually turning the shaft. Seems to work just fine now and doesn't stick!
thank you.

In my case, I had to use a pipe wrench and vice to manually turn the shaft on a 1.7 hp Gast air motor.. but as I got it moving, I kept putting oil into the air inlet and turning it. I let it penetrate overnight, and started it up the next day, and it worked.
Lesson learned.. be much better about lubricating air motors.
