Ok the Six Pack is rebuilt and installed.
Raised the coach hit emergency stop on the HWH and turned the ignition key off.
It has been over three hours and the air bags are completely inflated. If still looking good in the morning I will exercise travel mode and leveling to check those modes and see if any leaks develop after using the system. I really did not see any real problem with the plungers the dump valves were dimpled more than the others. Maybe that was enough for them not to seal.
The O rings at the base of the solenoids were worn. At least three of the valves were worked on and one was replaced since it does not match the others. The new one does not have a brass base. I saw three different type of greases used on the O rings and two places someone though more was better. I do not know who has been working on these but they did not know what they were doing. Way too much grease.
I used the Super Lube. I did not use the Dow 111 because I would of had to travel 50 miles to purchase a tube. Super Lube was the other recommendation and it was available at Ace Hardware 5 miles from my farm. The DOW grease is what we used on o-rings on the Seismic Vibrator trucks I helped design. The Super LUBE appears to be similar to the DOW 111 Moly Coat
I have some photos. Much the same already on this site. I will probably post the photos with a short description later.
Summery of work done.
1. Checked air bags, six pack manifold and all air line connection for air leaks. I found no obvious leaks.
2. Replaced the air drier on the 12v Aux air pump.
3. I obtained some desiccant and packaged portions to take with me when traveling so I can replace the desiccant when it is wet.
4. Used TOMS rebuild kit to rebuild the valves and new plungers. Some of the o-rings looked pretty bad.
5. Removed, inspected and cleaned the o-rings on the two internal check valves in the manifold. I found some white powder on the o-rings.
Note: Some of the support tubes came out of the compression fittings when I removed the air lines. I reinstalled the support into the fittings and carefully hand pressed the air lines back in place. I used a small block of wood to tap the support tubes in place. Then leaving the jam nuts and ferrules in place. I hand pressed the tubes over the support tubes. Then I tightened the jam nuts on the fittings.
I used denatured Alcohol to clean the manifold and air valves. Then used compressed air to remove lint and dry the manifold and valve parts before assembling the valves. The Alcohol we used to clean parts on Siberia was not denatured. Good for many more uses. Helped you sleep at night.
Thank all of you that made suggestions and informed me of the availability of the rebuild kits.
Thank you TOM McCloud for making these parts available to us all. Great price and great quality.
I will upload a few photos later there are many on the forum. My manifold setup is a little different than some of the others.
I made one mistake. I swapped the right air bag air line and the right travel height valve air line. One right air bag refused to inflate and there was air blowing out of the travel height valve. I scratched my head for a few minutes before I crawled back under the coach and found the mistake. The air lines were labeled correctly but I had a brain fart and swapped the two lines.
