'95 Dynasty Step Slide Air Cylinder Access

After engine shutdown I have been losing air from the front sector and after reading some step slide posts I had to assume my cylinder is defective and air is leaking past the o-rings and exiting the MAC valve. I can feel the air rushing out of what I believe to be the MAC valve exhaust port after I shut the engine off and crawl underneath to look for air leaks. If the air isn't supposed to be rushing out of the MAC valve upon shutdown then I assume the cylinder is the issue. My generator is fixed and I can see no easy access to this cylinder unless the step slide can be slid completely out. This would appear to be a possibility once the carpeted face plate is detached.

If anyone here has knowledge of this issue I would very much appreciate a response. Thanks.

Open the front generator door. In fact, take it right off. Your Mac valve is on the front firewall above the generator. The big one is the dump valve for the front suspension. The smaller one with three connections (maybe four, I can't remember exactly) is the valve for the step cover.

Find the air supply line feeding that Mac valve. Then drain the air pressure. Take off the supply connector and squirt a bit of WD-40 into the valve and replace the connector. Air up and try the step cover. That Mac valve sometimes gets gunked up and doesn't fully open.

By putting WD-40 in the supply line when you air up and try the valve the air pressure blasts the WD-40 thru the valve and usually frees it up.

There's two little adjusting screws on the side of the step cover Mac valve. Screw them both all the way in, and back them both out 2 turns. Then fine tune adjust them for speed and power of the operation of each direction of the step cover.
