hydraulic fan oil and filter

[Dan Williams]

You are right, it runs the power steering
and fan using 10w – 30 motor oil. 20 quarts. I wonder if there is a
way to extend the change interval. The instructions say to run the engine
at 2100 rpm and if the red light on the rear switch panel comes on then change
the oil and filter. I don’t know how one man can run the engine at
2100 rpm and check the light on the rear switch panel at the same time.
Seems like the light should be on the dash somewhere.

I think that is overkill. I bet caution is because the
tank reservoir

is where the expansion takes place and the cold oil airspace leaves

room for condensation. when you mix water with the hydrolic oil you get

a foam. the foam air can pack airpressure in the lines and screw with

the pump and rams. (the steering gets spongy) the fan pump and oil also

runs the steering on the pt's.--- In
