tag axle adjustment

[Whiskers]

Has anyone had experience in adjusting the pressure in the tag axel? I recently had a 6 corner weigh done by Weigh-it in Phoenix area. Guy has portable scales and comes to you, gives you a very complete spec sheet with findings and goes over recommended changes and tire pressures for the recorded weights.

In my case I need to put a little more weight on the tag thus taking some weight off the drives & increasing the front slightly. I have followed tag axel adjustment instructuions Monaco provided as an addendum for the 2001 Executive & Dynasty models. I have a 2002 Signature and believed the same instructons would apply.

The instructions are fairly straight forward and I followed them to the letter. Essentially unlock and adjust the regulator pressure setting, and perform a stabilization procedure by raising and lowering the tag to lock in the new setting.

The problem I experience is that the pressure I set and lock in does not in fact "lock in" to where I have set it. Instead it continues to rise. I adjusted it to 44 PSI (normal creep of about 2 PSI is expected so if you want to end up at 44 you start at 42). In my case, setting at 42 (hoping to end at 44) I ultimatey end at close to 50 PSI. I played with various starting points but still not able to finish at the desired 44PSI.

Any help or insight welcomed.

whiskers...Have you called Monaco Tech Support on this one? It is something that you may have to do in order to get an idea of where to look...

You probably need a new air pressure regulator on the tax axle. Maybe that is why it was off during the original weighing session.

Sounds like a bad regulator, it should hold the set point. The regulator can probably be rebuilt.

Thanks to all. Did speak with Monaco and they also suggested it might be a faulty regulator. My only hesitation is that the regulator does seem to hold a constant pressure once stabilized. I just can't seem to get it to my target PSI. I'll play with it some more and if the issue persists I'll get it changed. Cheers.
