The fluid in my resevoir looks horrible, Either way I'm draining it, and refreshing it with fisher blue, as I'm rebuilding my lift piston and replacing an angle hose anyhow.

I also had fluid penetrating into my motor resulting in black deposits in the fluid. I drained the resevoir and can see this black resedue stuckl to the walls and the pump. (wipes off easily).

This is what I plan on doing to flush the system.

Re-fill with Fresh cheap ATF fluid. Run plow for about 15-20 minutes to get things moving and warm,

Then drain that, again removing angle hoses and manually moving plow to get it all out, then refill with Fisher blue and call it done.

What do you think? Any better ideas?
 
I read elsewhere once you unhook the ram lines, and force plow side to side (not hard without hydrualic pressure) you can dip the hoses into kerosene, suck some of that up and blow that out.

I'm not going that far, but figured its good knowledge for the site here.
