Ok guys it has taken my Mack dealer a while to get my parts. Here is what I have with my leveling valve and control rod on my truck.
 

as you can see the bottom stud was broke off my control rod and the white plastic is broke off my leveling valve.
 

The bottom photo shows my new leveling valve and control rod. How does the control rod attach to the leveling valve. I have to be missing a piece.

It may be a Barksdale universal fit, and you re-use the arm..   Dammit, I dont know why I cant remember it..  I do remember small control valves with the threaded rod and tiny tie rod ends..   for R models,,   I guess im out, til my brain re-starts...  Sorry Ricky...   jojo

Damnit Joey get your shit together! Rickey needs help….

[Ricky Beals]

So should the arm have come with the lever valve or is it sold separate. I’m thinking I take the nut off white piece and arm goes there. Then put the stud without a nut (missing) on the other end of arm. That sound right guys?

 

Onyx610 thanks for the help. JoJo has been helping me. 

[Joey Mack]

yes, on how to mount the arm..

[Ricky Beals]

Thanks JoJo. 

[Joey Mack]

if you look back at the link Onyx posted, it shows how to mount the arm.  that pic is a rear supension set-up, but the same idea... I think what you have is a universal fit valve..

[mechohaulic]

mount the valve/ and the adjustable linkage; measure distance from the white plastic area by the nut to the treaded adjustable linkage. make a new arm with a piece of 1/16th thick x 1/2 in  wide flat stock (rough measurement ideas) drill a hole on each end ;;install

Ok guys got the valve and shocks changed. The airbags are holding air so don’t see a reason to change them out. 
 

So while I was under there working I noticed oil on drivers side front springs. After looking I felt like the oil was coming from the centrifugal filter housing. After cleaning it up and making sure hose’s were tight. I hauled a few loads of gravel and checked the area. It looks like oil is coming from this? Have no ideal what it is, maybe a vent for centrifugal filter housing. Here it is and maybe explain what’s going on here. As always thanks for the replies.

[Joey Mack]

Thats the breather... it happens..  have you put a new spinner in there? #2134  I think thats right. I typed it really fast...  If you get one from NAPA, make sure it is ALL metal...   trust me... jojo  P.S.  replace the lower elbow hose..  I bet it is as hard as plastic...  the nipple on the block is easy to remove, and reseal.. get that o-ring too..   if you cant, use good RTV..   jojo

[Ricky Beals]

Thanks JoJo, I replaced the spinner earlier this year. Didn’t get to drive much with replacing the camelback suspension and clutch. This just started happening about a week ago. So replacing all those parts should fix the problem JoJo. I will do it.

[Joey Mack]

it makes it fresh and new,  the elbow pipe will last for a couple years.  just one of those little things we overlook when trying to keep leaks under control.  jojo

[Ricky Beals]

Ok let’s go back and revisit the leveling valve and arm. I manually turned my valve to add air to my bags. I’m waiting on the lever to come in the mail.  My bags are not leaking down. So my question?? Is the leveler valve only to add air? Does it supposed to let air out of bags when truck isn’t running?

[Joey Mack]

Ricky,,   It does both... It maintains a cab level...  it will take air when needed and dump air when it is too much...  It is a simple system...   If you were to see inside the valve and how it works you would smack your forehead...

No. It shouldn't....

 

If the Bags are leaking down Overnight..? you have a Leak somewhere in the circuit..!!

[Joey Mack]

ok,, I just saw the last part of your question...  thank you Hayseed..  NO....  it should hold air...   the rest of what i said is true..    

[Ricky Beals]

Thanks guys, they are holding air I was just curious. 

[Onyx610]

Once the secondary gets down below 90 I think they will drop(I think). It’s not uncommon for the cab tilt back after a day or a few days of sitting. As said above by hayseed you just have an air leak(s) and you’re gonna have air leaks……So don’t be alarmed if the cabs down.
