Well, I rehabbed one of the air motors today.

I just used the old gasket to lay out a pattern for the new one in pencil and cut it out with an exacto-knife.

They had the material at O'Reilly's along with a couple of O-rings that fit pretty good. The O-rings were #219 out of a little red box assortment they had behind the counter. Not quite the same thickness, but they work well.

Put it all back together, hooked it up to the shop compressor... and voila! It works again and no leaks!

Got me to thinking... I have a pretty decent homemade cnc machine. It would not be hard to cut out a whole bunch of these gaskets if there was some interest...

So far as I can tell, the only true obstacle to being able to completely rehab one of these motors is the valve that has the red button. If that valve doesn't work, you're kind of stuck trying to fix it just by applying alot of air to either the inlet or the exhaust as there's no way to take that section apart.

The O-rings were about a dollar each. And the gasket material was $8 for a roll big enough to probably do 100+ gaskets. Most time-consuming portion was cutting out the gasket. Everything else was easy.
