Title: 2001 MCI Leaning After Shutdown
Post by: DanKeeton on November 06, 2010, 05:16:38 AM
Hey Guys,

Anyone have an idea as to why a 2001 MCI will lean to the passenger side only after being shutdown for about an hour?

Dan, I would start by connecting the bus to shop air and blocking for safety. the trouble is most likely one of the rear leveling valves sticking or leaking

ditto on air leak probably on drive air bag on low side  time for soapy water and squirt bottle. squirt leveling valve also..to replace it is under $50 do it your self.  should be located in front of duals.  may have a access door you can see it thru..on the 89  prevost I have the batt shut off door  access to it  the 98 you have to remove tires and mud flap to get to it..if its going down that quick listen for leaks..coach secondary air pressure drop that quick also?   Bob

Dunno anything about them but is a kneeling valve a possibility on that coach?

There is a kneeling valve, but it is only the front that kneels. The entire passenger side leans after being shut down for 20 minutes.  ::) Also tonight, I noticed it takes a long while after restart to build pressure back up. More noticeable on the back.

Dan prob pass side air bag or leveler valve on drive axle..your air system is split to primary and secondary.About 60 lbs both systems will be charging. so more tanks to fill up..good luck
