2002 newell air dryer

hi all, today was at the bus shop and we looked for leaks while up on the lift.

i have 2 valves leaking at the rear for the tag axle breaks which i will get and have replace. the air dryer is also leaking out the bottom of the assembly. my bus mechanic said it was a wabco systemsaver 2000 but i cant find that anywhere. i tried to get the numbers off the casting but they are too small for me to read. lots of road grime on it.

i likely need to get a new one. anyone know what model this one is?

pictures below.

thanks

Tom,
Google "Rockwell Wabco air dryer" and you'll find every thing you need. They are located in Troy, NY(according to my 7/96 owners manual) 800-535-5560

My manual is for a system saver 1000 & 1200 series, so it sound like yours is an update from mine.

he wasnt sure. so i will have to see if i can get the part number off of the casting.

there are several different versions of each of those.

thanks for looking. i looked in my books and there wasnt one for the air dryer.

Tom,
Looks like the System Saver 2000 is a twin filter air dryer. Yours looks like mine which is a System Saver 1000 or 1200.

Here's a part number for the 12V air dryer--S4324130010. I'm pretty sure that is a 1000. The 1200 look like a 24 Volt.

i went out in the dark and took a zillion pictures to get one that i could read the part number on.
Meritor WABCO 1200 System Saver Air Dryer - 12 Volt

part number 4324130010

steve, thanks so much for looking things up

the only difference between the 1000 and 1200 is the volume of the desicant in the cartridge. the 1000 is 1000cc of desicant and the 1200 is 1200. the BA 5374 is the replacement cartridge for the 1200 series if i cross reference the filter for the system saver 1200. that is the save filter that steve is using now.

now to find one cheap....
