I could always put a freq counter on it and drive to be certain of the final output, but on my A0 it does sense a 36 tooth spinning gear(i have counted the teeth:)) and the DS RPM is pretty easily calculated... OOPS: 36 teeth, not 26 teeth...

Yea the subframe is supposed to allow the box to move when the frame twists. The thing about captured spring is that they WILL impart stress on the box, and the box must be either designed to flex, or deal with this stress and transfer the force into the springs. Think of it like a 3 point...

Ok with stock wheels and 2:1 hubs(7.8:1 total ratio, at ~60MPH the driveshaft is spinning an insane 3375 RPM. If I recall the output speed sensor is sensing a 36 tooth gear, so that would be 26 pulses per revolution or 121,500 pulses per minute. Since 60 MPH is 1 mile per minute that is also...

Well not knowing how their box is connected, hard to tell what was actually moving. Moving around on my frame, I have noticed quite a lot of movement from the tires themselves.

Yea that sounds weird. Perhaps they did not have enough/any spring preload... I am also not sure how "noodly" the unimog frame is... if they have springs pre-loaded they would have to apply enough force to further compress them or the frame would have to twist to allow the hab to move...

You are not missing it, it is not in the books... I actually got in and counted the gear teeth that the sensor looks at. I can look in my notes and give you a rough idea of PPM when I get home this evening...

There is an output speed sensor in the transfer case. This outputs a pulse per mile output signal(sensor reading an intermediary gear tooth). it feeds thru the transmission controller, thru the VIM on an A0/WTEC2 truck and on to the speedometer and then on to the CTIS controllers. On a WTEC 3...

well if the reg is the only thing providing the restriction and 2 different ones are doing the same thing, it is probably right. it just seems a little high from some of the specs I have run across...

The things a metal hotbox with greenhouse windows... Most electric options you may find a little anemic for the cab, and they are a heck of a load for the alternator... Your best option is probably going to be an engine driven compressor system in the 25-30K BTU range. I haven't seen any of...

Well either the regulator is causing the restriction or something else is:)

Did you try pressurizing it with the primer with the reg removed?

Well if the trans is doing work, the engine is burning fuel and making heat to accomplish that work(And the trans is probably making some also:) if you are driving around and the thermostat is regulating to 185, then thats where it should be unless you don’t have enough airflow to dissipate the...

The brass poppet is a pressure regulator. that's how the system deflates. it opens the deflate solenoid and sends system air to that 6.5 PSI brass relief valve. in this case it acts like a regulator and drops the system pressure to just above the wheel valve closing pressure to allow maximum...

Yep, either the control valve is not opening cleanly or the vent port from the pcu thru the floor is clogged. If the system cannot vent below ~5 psi, the wheel valves will stay open and empty the tires. the sound under the truck is tire air escaping thru the fromt dump valve on pax side of...

For the coil and wattage. i have seen 2 different solenoid valve types used on our PCU modules. I am not sure wether they use the same coil assemblies... The solenoids portion consists of small pilot valves used to manipulate air to cycle the larger bore valve core/spool valves…

I believe they used TL110 on the A1R to feed raw battery power from the LBCD to CB60 and on to the ECU… I have not seen it used referenced on the earlier A1 truck diagrams, but that doesn’t mean they didn't use it for something… on the A0 it went to the alternator F- terminal and fed a...

Tl110 on what year and model truck chassis? Or to be more specific what year and make wiring harness?

Yes that is strange. the test port/tap is after that second filter right? It should be a straight shot from the second filter output to the front of the head via a hardline, past the injectors in the gallery in the head, to the regulator in the back... Is it possible that the hardline up to...

If I know I am going to deflate, I try and throw a jack-stand under the axle…

Did you ever run the regulator output thru another line into a bucket?
