2935: Adding spacers in pnuematics
I'm trying to confirm whether adding spacers to pnuematics is allowed. To install spacers, the end cap had to have been removed. And according to R19, this technically counts as modifying the part, but the end cap was reinstalled to its original state, and the pnuematic looks and functions identically to a new unit. The end cap came off with normal tension; no glue nor screws holding it in. Given that, and the part being returned to its original state, I'm unsure as to how this fits within R19.

Removing the end cap of a VEX IQ Pneumatic Cylinder to add a spacer, as you've described, is a modification of the part and is disallowed by rule <R19>.
