ARO Step control valve

[antique405@...]

Chuck. I replaced the valve on my 83 PT with Alfa valve from Grainger. Had to make minor change in mounting but easy to install. Hope this helps.

Alfa A2125D 012-D

Flow valve 42J85-1

12volt coil 2G503-2

We developed a bad leak in the ARO step control valve during our trip last weekend. The spool valve was easy to rebuild using “O” rings from the faucet section of ACE hardware (3/4” X 1/8” thick - $0.29 each). The problem is that the rubber on the back port of one of the pilot air valves is bad so there is a leak when it is energized. There used to be kits available for these valves but I can’t find any since IR bought ARO.

- Has anyone found any parts to rebuild one of these valves lately?

- Or does any one have an old valve around that I could buy for parts?

- Or, lastly, does anyone have a part number for a valve that would replace the current one? (ARO Part#5840-2929-02)

We head north for the holidays and in very cold weather even a small leak creates problems.
