It had a 1.0625" bore piston with the piston rod pressing directly on the 3/8ths standoff above the traction wheel.
(the entire module was packaged in a 3x3x.125wall aluminum tube, so the piston was face mounted to the top)

The module range of motion was well defined elsewhere (spring tab through the top of said 3x3 tube) so there was no room for the piston rod to go anywhere/slide off the standoff it was pressing against.

And the arc motion was so short that was not a problem either.

One advantage to this is being able to remove the module with just the pivot bolt and the small spring we had that returned the module to the up position.

Let me know if you have any other questions.
