Air System Schematic

I have been following the various recent topics involving the air system.  I must say that I am gaining a much better understanding of all the bits and pieces of the system by just reading these posts.  Thank you to all the contributors for that. 

I have been trying to relate the topics to the air schematic that came with my coach.  On the schematic many of the major items are labeled but the smaller items only have a letter within a circle to identify them.  I do not seem to have the key for these designations.  It seems there are items A through U.  Many of them are fairly obvious but I am not sure about some of them.  One question I have is the identification of item P (see the attached file).  Is it the air governor?

Is there a key to this schematic somewhere? 

Thanks,  Richard

Richard,

Yes, item "P" is your governor.

Correct - item P is the D2 governor.

As to the "Key" for the schematic - I asked exactly the same question when I joined the Forum.  If there is such a thing, nobody came forward with a copy, so I guess it doesn't exist?

Would it be possible to post the entire schematic as I do not have a copy.  Thanks.

Jerry, this is the air schematic for the 2001 U320.  There are differences between this year and later years but it is probably pretty close to earlier years.  I hope it helps.

Looks like some differences because of the slide but the leveling system parts look about the same.  But it deserves a very close look.

Thanks Elliot my U270 and your U295 air system is probably the same or very close.  I was able to print a good copy.
