My air step is hanging up during extension (opening) and is not fully
extending without 'help' from my foot, shaking the step a bit. No
problem with retraction (closing).

Lubricating all pivot points did not help.

Air expels during the opening and closing process, as is normal. Once
the step is locked into place, either open or closed, it stops.

However, when the step hangs up (partially open) air continues to expel
from what I believe to be the step solenoid valve. In particular the
escaping air is coming from one of the two 'spark plug shaped' devices
on the bottom of the valve.

Advice appreciated ... and if someone could give me the proper name of
the 'spark plug shaped' devices, that too, would be appreciated.

I had a similar problem, except mine would not retract. I talked to Kenny
Rodgers at Coach Craft, was arranging replacement of Primus, he said that
the step valve is the lowest part of the air system and any water that
accumulates will go there. His suggestions, and it worked for me, was to
remove the inbound airline, purge, put some WD-40 in the line, reattach then
operate the step many times to expel any water remaining.



When it WARMS UP I am going to put a small separator on that line to prevent
the problem.

Roger,
Those are adjustable pressure valves to regulate the air flow in & out.
You can take them out & clean them & reinstall. Sounds like you have
some obstruction in one that is preventing the correct volume of air
flow and shut off or it has moved out of position.

When i have been in freezing temps- seems like the last 2 months~ my step would
operate- but expel air in the retract position. Upon driving in warmer temps,
the step does not expel air.

I had the same prob as a symtom to a bad seal in the ram. When
I would tug the step fully open the air hissing would stop. (My
94pt40 has a non spring ram with two air ports) If you remove the ram
and blow air in, to push the stroke out , the air should stop blowing
out the other port when the stroke bottoms out. if the air continues
to blow out the other port the seal is bad in the ram. You may be
able to remove both airlines to the ram and test it without removing
the ram first. I tried to split the ram open to replace the seal but
the Clippar ram used on my bus could not be serviced.

The step cams open and does not require pressure to hold it open.
The ram is duel acting (pushForce pullForce). To open; one valve
pushes air into the ram thus pushing the stroke out. The other valve
escapes the air as exhaust. The only exhaust on a new ram is the
content of the unopen ram. what you hear is air passing the plundger
seal in the bad ram and adding to the exhaust. The movement of the
step hindge just before the step cams to an open rest require the
most ram force. Your ram may have been wearing out over time and now
it has too much blowby to pass the cam and lock the step out.
Clippard.com has an online store and I think the exact replacement
for my bus was around $200.????? The last two numbers on the Bad ram
were SP or somthing like that which turned out to be special order
and not important. I upgraded the seal within the ram for $35.00???
to a "V" which stands for the name of the rubber compound used to
make the seal.

The fix is easy but take care not to lose a finger in a surprise step
movement. I think moisture in the ram freezeup and cut the plundger
seal and or dirt gets in through the wiper seal at the strope end?????

Are all Wanderlodge steps supposed to lock in the 'out' position. Mine comes
out when aired
up, but if parked, once the air pressure drops, step becomes limp and flops
around. Where
would I find the mechanism which holds it out? I took a quick look under there
once and
couldn't see any obvious locking mechanism.

My step locks when open and once the air pressure drops it will open
automatically and lock in the open position.

When the air pressure drops off, the step comes out and locks in the
extended position. There's a switch on the dash (at least in my
coach) that will also set the step to be extended so long as the
engine is off. If the engine is running, and the door is closed, the
step will retract once air pressure is about about 85 lbs (no matter
where the dash-switch is set).

Look right under the step where the ram connects. It is a simple mechanism,
latches with a spring and unlatches when the ram pulls on it to retract.

Kerry:
On an 83, I noticed that it is a mechanical linkage that locks the step in the
open position. It is a spring activated mechanism, and when the cylinder
retracts the step, it unlocks the mechanism first.

On my 84, I have two air cylinders, one that locks the step in place when
extended, and one for extending/retracting
