R model tractor air system

[nicste]

Good day

I am looking for information on the air system on a RS797T. I would like to redo all the piping that is currently a mess. Does anyone have schematics, picture or information on the layout of valves and pipe the systems correctly?

Did the R models have 4 circuit protection valves before the primary and secondary reservoirs after the supply reservoir? I am working from the Bendix schematic, I believe there should be a third reservoir for auxiliary functions like the diff lock and wipers that would be supplied last from the 4 circuit protection valve.

Thanks, was trying to figure a few things.

I know the tank isn't that big compared to most trucks I've run.  I can get the low air buzzer going just moving it around the yard and having to jocky around stuff going forward/reverse/brakes.

Considering putting an air dryer, the wet tank had oil, and it's made it's way through the whole system over the years.

In the dash it's a lovely blend of misted oil from the air switch exhausts and caked on dust.

If you don't have a drier you need to drain the tanks of moisture everyday
