I would agree with wolfe10. In many years of working on heavy equipment, I don't recall a filter in the pressurized side of the pump. Usually it's in the return line to the tank.

I'll have to trace the lines a bit. I had thought the pump's pressurized output went forward to the steering and the lines on the way back went through this filter before the hydraulic fans.
There is a set of filters stacked within the main reservoir at the engine door next to the roof ladder. Maybe this spin-on filter is just an extra filter for protection of the sensitive and expensive hydraulic fan motors. I could see enough to see that after the spin on filter the fluid ran to the fans and fan controllers.
I posted in the hope someone had experienced this before and hopefully could point me straight at the likely fix. As with so many things I'll keep poking but I do appreciate any and all suggestions of things to look for and try!
