Rebuild suspension

I will update my info for my files. Thanks

While you have the spring beam out, good time to clean it up and paint.
I added the extra support angles for the bottom (piston) like yours has. Have not tried taking the bags out with them yet!
Did the threaded rod come out, or was that the main problem getting them out?

One rod came out and the other didn't, which caused another issue by not being able to push the bag over to pull the shackle bolts out . I just had to take a chance and put the nut back on the shaft and real lighten the second nut hard (like 80ftp) . That did it. The main issue is the air connection on the top, it will not let you slide out the bags without dropping the beam.


What to watch out for when taken the nuts out of the threaded rod on the bottom, is to only let your socket grab the first. If the nuts lined up and you take them both out, you are sunk and you will not be able to get the shackle bolt out.

Tag axle controlled dual valves:

Nice drawing of the Model 8050, which is very similar to its predecessor. Model 8015. They were used on Airstream Motorhomes since the 310 first was introduced. They are not Tag axle dependent, only the leveling valve control varies.

A couple of points I find important :
1.The red line shows the relation of the Spring Stirrup (Item 2) to the side view of the Spring beam. I have seen several and 1 in particular that were extremely tilted. I tried to make the owner of that aware of it without success. The plate that sits on the spring beam needs to be parallel with Frame cross member.

2. The string Stirrup Bolt (4)and Nut (5) is 5/8 fine thread Grade 8 with Nylock nut, which should be replaced every time its removed.

If you look closely (blue outline) you will see that the Bolt was inserted from the inside to the outside. Yes, I understand the need to torque the nut, but if you ever want to replace the Trans rod bushings or the airbags, you may have to cut the bolt to get it out. Grade 8!! I reversed them.

3. My Trans Rod Bushings looked just fine to me until I pulled them out. Wow, the straddle pin was worn and the bushings were shot.
