Sorry, was going to type this, his user name is Plasa...

5 solids is an unrecoverable internal fault. You can try hitting it with a hammer, but beyond that it is now a paperweight. Mine was the same, I used 3 switches, a relay and a pressure gauge and control it manually. Search electric over pneumatic manual ctis, also have videos on utube under...

I dont think the troubleshooting guide goes as far into it as you have. They the assumw the controller is ok, so they say If 5v from controller is ok, replace the sensor. Was recently helping someone with a failure and worked our way to the pressure sender also...

I wonder what procedure he was following? The only place I have seen the ream process employed was after you replaced the cups to provide a smooth properly angled surface at the correct depth after the new raw cup has been pressed into place. But unless you detect damage, once the...

Well a 24p manual might show you if there is a difference in part numbers on the PCU components between the different trucks. I would not think there would be though, as the relief pressure really needs to be that low(just above the pressure that opens the wheel valves) to deliver the fastest...

I believe they are absolute so at .05v per PSI, 14.something psi atmospheric pressure should yield .7 something volt return. Dont forget garbage in=garbage out. Those voltages above assume a proper 5.00v input. A different input would yield a different response per pound when divided by 100...

You should be able to probe the sensor wires to see ground, 5v from the controller and whatever the return voltage the controller is seeing coming out of the sensor. Of course it needs a good wiring path between controller and sensor…

Ok, that was one of my other questions, does it fill to the correct pressure. It uses a 0-5v 0-100PSI sensor. It has 3 wires. It gets ground and 5VDC from the controller and it returns 0-5v to the controller based on the pressure it sees. when you were working on the PCU did you remove the...

That doesn’t sound like a very aggressive deflate. it looked like it ran a full deflate cycle then faulted as it checked pressure. If that relief were partly plugged, it would not vent the manifold down to that low 6-7 PSI. The dump valves dump based on pressure differential, if the relief...

The brass relief would be the place I would look. When it starts a deflate cycle you should get an initial woosh out of the relief as it vents pressure down to its set pressure(~6.5psi). It will then vent air slow and steady as it purges the air being fed back from the dump valves to maintain...

Well I suspect that a different pressure program would indeed have different overspeed points, but i think you having an overspeed issue with a newer model controller in an older truck(yours is an A0?) would probably be related to the differences in pulse per mile input. I believe it is a fixed...

If you disconnect the return line at the hand pump and fluid comes out of the line while pumping, the problem is probably still in the return side of the hand pump. If fluid does not return thru the line when pumping, then it is the line or something upstream...

It probably wont fix the overspeed...

Here is one with the control lever...

They make different variants of this pump, and on some that is where a control valve is located. Does that “tube” handle and the piece it is connected to rotate? It should be able to rotate clockwise 180 degrees It looks like it is bent down as it should point straight back. it reverses the...

Got a pic of the pump? The filler is usually a allen plug, front left when facing the pump. If it wasn’t sealed it would overflow whenever the AOP is used as the return pressure needs to get over 5PSI to find its way back to the AOP reservoir…

First off the pump is performing the work you are asking of it(raising cab or spare tire), correct? there are a set of steering check valves in the system, but they are on the return to the air op pump(circled in red). The hand pump is sealed, so when you pump fluid out of it, it goes into...

How does the front center diff fluid look? The front is 3 different reservoirs 2 hubs and center axle, with the vents tied together but they should never share any fluid… you should drain the center diff fluid and inspect it at the very least… this almost looks like some motor-pool maniac...

The bracket in question is #17 in this pic. Missing, broken or loose, you probably have a timing case crack. People have welded the case cracks in place, but the support bracket needs re-installed properly at any rate…

My low pinion DS is currently setting at 61” or 155.25CM, but I have no weight on a bare chassis right now so my suspension is extended a bit:) high pinion being 1/3 the angle(~3 deg?) and a few inches shorter(less mass) would definitely reduce the longitudinal forces. Under 5.5 degrees would...
