Some nipple-head at the Eagles Nest in Nashville, where they did some repairs in preparation for sale for the guy we bought it from, decided to replace only 5 of the 6 rear bags. I finally got around to pulling that last one (it was 61 wonderful degrees in Chicago today).
The bag was dated 1984:eek: Its like the plumber with the bad pipes I am:rolleyes:
Our bus has no Norgrens. I will take a picture of the beautifully simple and inexpensive valves they used to use, before it goes back together.
I am also upgrading to maxis on the tag and replacing the drive maxis from the 30/36's to the 30/30's replacing all the 1/2in rubber brake hose to 3/8 with the 2 piece reusable ends, upgrading to gas shocks and replacing the drive tires with 11.22-5's. This will give me all the same very readily available and less expensive components that the trucking industry enjoys
The fat lady is tuning up.
I had the opportunity to scarf up a set of the elusive Mae West bags (the0126's):) That same shop replaced 1 of the two up front and the L and R sides are different. They are going on the steer and I plan on pulling the brake drum to see if I can find that thunking sound down there in harder shorter stops. I remember a couple other folks mention that same thunk up there, hopefully I can definitively resolve that.
-
Strictly theory Joe, but we had the thunk on the 87 coach, but not on the current one. If I had to guess I would say it is the front axle attempting to rotate when a lot of force is applied such as braking in which the tire on the road wants to stop rotating, while the chassis wants to keep traveling.
If I had to point at one thing it would be the radius rods and the bushings compressing once the forces exceed a certain value. This is only a guess, but I was all over my old coach trying to find it.
-
I hope not cause I have put new ones in up there already.
-
Joe,
It sounds like it's nice to have your baby back home. I wished you could just put a few things in it and head over to Havasu and join us next weekend.

Dale, As an old Pogger says: Roger that!
-
Brian,
Now your going to get in trouble for calling Roger old! :)
-
Although we can not physically be there we will be participating:eek::confused::D
Don't ask.
-
JOE.......I have had that same thumping sound under hard breaking on my present and previous Prevost. Both 1989 models. Have no clue to the cause. I hope you find out for us.
-
Joe, I don't think it relates to the age of the bushings. Our coach was 2 years from new when we bought it and it made that noise any time I had to do a hard stop.

I finally remembered to check out my front raise measurements as Ken and Ray did. I think the Liberty likes the warm weather, 80 degrees and I got exactly 6" of lift without lifting the tag, at high idle and a governor pressure of 130 psi. It took just over 2 minutes to raise and I have 259 bags.
