Scott,
What does your tag pressure gage read?

Now tag axle pressure
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.

Now tag axle pressure
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? Jay Darst 85PT40 --- In WanderlodgeForum@yahoogroups.com, "Scott Forman" <sforman@...> wrote: > > Half way between the 50 and 75 lines.

Jay, My 38'WB weighs more than your 40'. Tag pressure is 70.

Now tag axle pressure
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?

Now tag axle pressure
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. n Jan 4, 2008 9:01 PM, Gregory OConnor > Tag axle pressure is a factor to weight on the tag relative to the > pressure on the drive.

Now tag axle pressure
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. Glenn Allen 1986 PT-40 Marietta, GA |

Now tag axle pressure
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.

Now tag axle pressure
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.
