Hello,
I have a question about the pneumatics PTO system. The system is fine when not carrying any load. But when it’s got any load it doesn’t work it sounds like clicking noises. It seems like the pistons aren’t strong enough to hold the gear in place. When the piston is retracted it seems to be fine. It’s the extension that causes the problem. Any ideas?
If it isn’t strong enough, try using some rubber bands to assist it.

I agree with @Gigahertz.t, see if you can add a rubber band to help with the extraction. You might want to add a thin teflon washer inside the linkage to let the parts slide a little easier. Lots of the Hexbug kits come with them for this reason.
all you need to do is not use hybrid gears and itll work
My kids used PTOs prior to pneumatics. Look at the video below which might help you understand the issues better.
From the video, you can see they were able to achieve reliable gear engagement and and good power transfer and torque even without pneumatics. What the pneumatics helps with is the reverse direction of the system. So as long as your set up your system to take the high loads in the favourable direction, you can just use the pneumatics to help with the reverse direction that has a smaller load on the system like out taking and elevator down but set up the system such that the higher loads will still work even without pneumatics.
With the gravity gears, one direction of rotation with have very good engagement even without pneumatics. You want to match that direction with the high load function. Pneumatics will never be strong enough to hold the gear in place for high loads if you have chosen the wrong direction of rotation.
I hope that helps.
Cheers.
