Rebuilding a air assist unit

[peashooter]

How does pushing VS pulling give something more force? Doesn't the torque valve supply the same air pressure to the left and right air ports?

Yes same pressure but less piston area on the rod end.... Which equals less force. All single rod pneumatic and hydraulic cylinders will have more force when extending.

Makes prefect sense, thank you.

I like that you've got the cylinder up higher out of the way. Why did you decide to mount it backwards?

Honestly, I just put it on there. It does take a little less air hose with the cylinder mounted this way.

One thing I don't like with the stock air-assist is the cylinder sits so low (more chance to get damaged). I tucked this one up as far as I could without interfering with the driveshaft.

Ty, some of the kits have larger air cylinders than others. Do you know what size your air cyl is?

I think mine is 4". What does the stock cylinder measure?

I knew you'd ask that, let me go look.

Just under 6" outside to outside, so I'd say 5" maybe.

Looks good, is it driving good for you? Does it want to return to center at all or is it mostly a manual operation?

Here a link to a post where I give an evaluation of the setup. http://www.steelsoldiers.com/showth...-Possibility&p=1479174&viewfull=1#post1479174
