driver's vent air cylinder

[Gregory OConnor]

Some air cylinders only push out or pull in. they are called single
acting cylinders. the vent is needed for the release of air from the
noncharged side of the piston as it is pushed or pulled. The only
time it will pass air is during a movement . static release of air
is a sign of a damaged piston seal. The entire stainless cylinder
interior wall surface is uninterrupted (full distance of stroke)and
it is more likely that the rubber seal is damaged.

Moisture in the cylinder freezes and the ice chews up the piston
seal. Or dirt gets past the rod wiperseal and buggers up the piston
seal. Or you meet the requirements for Clippard's planned
obsolescence. The Clippards I worked on are more or less non
servicable. Clippard . com has a good enduser web order store and the
prices are less than MSR.

Some of the airline fittings have a plastic collar near the bace of
the fitting. pushing the collar toward the fitting releases the air
line.
