I wonder how radios would work with a positive ground since the outer shield on the antenna wire is grounded

yes.... yours is a 2 valve, and I think in '86 the 4 valve came out..   '90 was the first E-7...   

my 1985 came with a 4 valve 

It’s amazing how one person’s leadership can change the course of a company

nice picture of "open air shop" ; sure brings back bad memories for me seeing a R-model on trailer. after loading a R-model on non-detachable lowbed and being in a major hurry;; stepped out of R model forgetting i just  loaded it ; stepped out to a long way to ground level!  one of many reasons my knees are past worn out. 

Ouch, that hurts me just thing about it

I have one in the truck but my friends rarely turn there’s on.

back before cell phones that was all we had 

today some of the clubs insist on proprietary radios or GMRS, FRS radios 

Back in the 80’s I drove a 1975 DM600 roll off truck that started out as a power company truck. There were two air levers on the top of the dash, one was for the power divider lock and the other was differential lock. In the mud I would flip both levers and it would claw its ways through the mud turning all eight rear tires

currently i have an ex US Navy truck that has Detroit lockers in each rear axle and the air lockable power divider. 
 

I also have a two axle truck with an air lockable rear axle. It is actually common for the tractors that were ordered to haul bottom dumps her in California 

The emergency, red, is connected to the tank with no valve to pressurize the tank

the service, blue, is connected to the valve that is mounted on the tank. 
 

thr brake chambers are connected to the valve on the tank

the valve on the tank serves as a relay since the service line does not produce enough air to operate the brakes by modern standards 

the maxi lines are connected directly to the tank

the port location on the valve varies based on the valve

I would expect with a rig that big there isn’t much you could need to perform a rescue that you wouldn’t have with you. Probably biggest challenge would be remembering where everything is!

 Thank you for sharing @GA_Dave

You need a short bus to follow the rig around to transport the rescue personnel 

Quite normal 

look up COLA air brake test

most trucks will loose air, it is only an issue if the compressor can’t keep up.

I don’t start chasing the leak until it happens over a very long lunch

Thanks.Oddly,when removing,a 15/16 wrench on the flats was too small,a 1" was too big,a 23mm fit perfectly.Would there be  a metric  version of these fittings?

Was there paint, rust, corrosion  or other crap on the fitting or was it worn away to a smaller size? 
 

Garrison can rebuild or remanufacture it.

the end piece that the tie rod screws into is NLA 

if you pm me your email address I can send you the manuals 

Is it the cylinder that connects the steering box to the pitman arm that is leaking? This is actually the control valve.
 

this is a garrison control and to the right of the fittings it says garrison, has the part number and date stamped in the body.

Why do you think the cylinder needs to be replaced?

Since you say power steering cylinder I suspect that you have an ad on system and not an integrated power steering box

if it is a garrison system. Garrison is still in business and will rebuild there system 

Please post some pictures of the system so we can help you 

Do you have any more pictures of the truck and trailer?

how much rust is there?

A few pictures from the carnival summer 

What are your plans for it?

Do you have a real job?

The coolant fan should be running when the ac is on and the compressor clutch is engaged, especially standing still.

the ECM may turn it off when the truck is moving 

the ac will not work well unless air is moving through the condenser
