  • Prevost Suspension Drawings / XL II

    Posted by Brady on February 26, 2014 at 9:25 pm

    Trying to isolate leaks in the suspension / leveling system on Prevost side and need to understand difference between solid lines on the drawings and those that are broken or dotted type lines? Have made the 30′ x 40′ larger size drawing Jon always recommends to work from… I assume since this is a Prevost drawing, all converter installed components are not reflected??

    Coach leans to the right side after a short period of time..

    Any explanation appreciated.

    Thanks,

    It’s the air bags on that side or fittings or 3 port norgren between tag and drive axle or the 5 port norgren, or ping tank on that side.

    Thanks as been through there with soapy water and nothing found but will be back there when in the air again tomorrow as may be in either of the nogrens themselves… i wish i understood the drawings better and difference between what is Prevost’s and what add on are the converters…. as well discussed here many times, this will make you pull your hair out….

    I not sure on your drawing but on mine the aux air are dotted lines but some are aux air and the line is solid ,start at the aux air tank and follow them we laminated mine used erasable mark then you can follow them it goes to steering bay on mine when it leaves tank it should have a D coming out of tank that means delivery mine goes to norgren filter in steering bay.

    Brady,

    Liberty modifies the air system for their Auto Level. In your steer bay, you’ll have 2 Norgren 3 ports that control the 5 ports in the rear. Check those, I labeled mine port and starboard so I know the position. Here’s what they look like, leaks included:
