Ok, thank you, David L. We will check the valves, I was also trying to find out the part number of the bellow. I did find a 1995 Dynasty was the Firestone #W01-358-7400 and I do know that ours is currently Firestone brand, we couldn't find a number but did find 22C on it which does correlate with this part number.

Coach is leaking air on Drivers side, just completed a road trip, next morning, drivers side has dropped. Please let me know, where to begin, one RVer we were parked near said it might have a leaky diaphragm.

Thank you for all the advice and ideas. I ended up taking the bus to a hydraulics repair shop, and the mechanic thought he might be able to rebuild it, then he found the motor was actually in pretty rough shape. So he found a part the Sauer Danfoss SNM 2/17 CI06 LFU1, was able to order it, second day, and he fixed it today with the new motor. I very happy as we got this done, when at first it seemed almost nearly impossible to do in one weeks time. The part was $400 and the labor was $425.

Ok, yes, my apologies this is for a hydraulic fan motor, not a pump. There are two motors and two fans and the number I posted was of the motor that wasn't leaking. I did take it to a hydraulic shop this morning, and they were able to see a part number SNM 2/17 CI06 LFU1 I believe this is a Sauer Danfoss, it stated made in Italy. I have started the process to find the motor, but the gentleman at the hydraulics repair thought he might be able to repair this? So, I am still trying to locate the motor, and will call some companies today and see if this part is available.

The old forum would be wonderful to see and read about. It has really been quite difficult finding any information on this system. After looking at the VIN this coach was from Indiana.

1996 Monaco, 8.3L, apparently there are two of these pumps, each attached to their own fan blade. It is not easy to get to, we did find some numbers on the pump that isnt leaking.
