Scott,

What does your tag pressure gage read?

Half way between the 50 and 75 lines. I thought about it after I
typed the post, and the only basis I really have for that
being "normal" is the fact that it is what mine has always read. I
can't say I recall reading or hearing what it is supposed to be.
What is yours?

Scott,

my tag pressure agage reads 50psi. Seems to drive fine.

Axle weights are approx:
stear = 13,400 lbs
drive = 20,000 lbs
tag = 8,000 lbs

Thats full of fuel and water.
Gray and black empty.

Have you weighed each axle?

[Gregory OConnor]

Tag axle pressure is a factor to weight on the tag relative to the
pressure on the drive. Since the drive axle pressure is fixed and
not monitored via the dash, the tag pressure that proves even heat
across the six tires after a run is a safe bet.

When backing in a site or driving on uneven surfaces tag pressure
sudden increase may reveal that the drive axle has lost traction.
If rpm of the detroit is not responding with movement, rpm should be
kept down to minimize the sudden torque stress once the drive makes
traction once again.

Since dropping the air on the tag helps make tighter turns and gives
the bus safer traction in low speed areas, I think The gauge is more
or less an indicator that the tag bags are full or not.

the tag axle Wanderlodge is called "three axle tag". A three axle
truck or bus that has two drive axles connected by a driveshaft
between them is called "TwinScrew".

My tag reads 60 when full. when I dump it via the TAG dash
electric/air switch, tag gauge goes up to over 100. my thinking is
that the drive and tag valve are cross wired, and I am dumping the
drive.


What is the engineered reaction to dumping the suspension switch
ONLY ??? will that also dump the tag?

Inflate suspension first, tag second. Dump tag first, suspension second.

If suspension pressure is low and dumping tag, the tag pressure will read
beyond normal.

Our tag reads 55 on the gauge, same as the blue book specifies.

Repost with the correct subject....sorry

Scott,

I believe this is the way the rear air works for ride height, but I'm
sure someone on here can correct any mis-conceptions I have:

There are two ride height control valves in the rear that controls
the rear frame height by controlling the pressure to the drive axle
air bags. You can adjust the control height rod to change the height
of the rear, but this only affects the drive axle air bags. This
must be done on a level surface, and there are specs for the actual
height that should be measured when adjusting.

The tag axle air bag pressure is controlled by a pressure reducing
valve located on a cross member just behind the tag axle. This is an
adjustable valve. Conceptually, the tag axle should not be used to
control ride height, but should be used for load distribution. As
you increase pressure on the tag, the load will be removed from the
drive axle and shared by the front and tag axles. Too much pressure
in the tag can cause too much load on the front axle. Too little
pressure on the tag, can cause wheel lock-up during agressive braking
and also possibly overload the drive axle. So, depending on your
load distribution, the required tag air pressure will vary from coach
to coach.

The pneumatic diagram for my coach recommends a 40psi setting for my
tag. I think this is too little based on braking tests. I believe
45 to 50 psi seems to be better for me. I will be weighing the coach
soon and making final adjustments based on axle weight distribution.

I replaced my leaking Tag pressure reducing valve with one I ordered
from NAPA (they ordered from Bendix). My docs call for the RV-1
279926 40 psi. I ordered the RV-1 278247 50 psi version. They are
both adjustable so either one will work. NAPA has some "cloans", but
I don't recommend using them because the ports are arranged
differently and will require a plumbing change.

So, hopefully, I have all of this correct.

My tag gauge normally reads about 65# (as is specified in my blue
box). Dumping the tag axle causes the gauge to drop down to near zero
(after a few minutes). I always dump tag first, then main suspension
-- although sometimes in close succession, as when preparing to drop
the jacks in an RV park. I've never seen the tag pressure go up above
70 (sometimes, while underway, the gauge 'jiggles' between 60 and 70
-- from suspension movement, I presume).

I don't generally pay much attention to the tag pressure, except to
verify that it's come up during start up phase before a departure --
and occasionally, while on the road, I'll scan all the "minor"
instruments to see that they're in normal range. For example, exhaust
gas temperature is not much of an issue, except when climbing a long
grade. Pressure boost also is rarely of interest except climbing at
higher altitudes, etc. The top row of gauges get more regular
attention while on the road -- and I suppose they're positioned as
they are due to their relative importance. Since the tag pressure
gauge is in a hard to view spot at the bottom edge of the panel next
to the steering wheel post, it's position suggests relatively low
importance.

You may be giving the designers more credit than they deserve. Otherwise it
means that on my coach tag pressure is very important, as it is top row just to
the right of center.
