In the spare tire compartment of my MC5A, mounted in the overhead frame rails is a small brass value with single inlet and outlet ports that has a adjustment screw the size of a dime. It continually leaks a lot of air that is easily heard while walking around the bus with the system aired up.
I've looked in my original manuals and can't locate any info on it. It's probably a regulator of some sort but seems strange that it would vent like this. Any comments appreciated...

It might be the entrance door quick release valve or the entrance door lock air valve. |

Thanks for the response Ed turns out, after looking closer at my books, it's the pressure regulator for the wiper system. I don't believe it should be leaking the way it is so I've got a call into International Bus Parts for a possible rebuild kit.
Thanks

You can probably go to NAPA or any truck/air brake shop and pick up a generic regulator.

Hello Tom.
When you price a rebuild kit these days, and then price a replacement unit, it often isn't worth the savings.
After you open up the unit, spill the bits under the bench and discover that some part of it is corroded, or you break it trying to disassemble it, etc, etc.... and then you end up having to buy a fresh one anyway, and whether the kit will be taken back without penalty?
I find the job of getting the rascal out of there is challenge enough with rusted bolts, and those copper air lines having fused themselves to the brass...
When you buy a fresh one, it is just that, fresh, and of no concern again for many, many years.
And then we have time to find more things that need money spent on them!!!
happy coaching!

I'd really like to find a fresh replacement for this little regulator. Len mentioned using a generic one from NAPA, but it's been my experience here in Grants Pass, Or. that the parts guys are young and not really eager to plow thru books to find something that might fit. So if anyone has a direct source let me know. Also I can't find a setting value for this regulator. 120 on the input side, what's the output value? |

If it's for the wipers, I'm guessing around 65 psi. Should be a spec somewhere for that. Regulators are pretty reliable. Check Home Depot or Lowes in the air tool dept.
