WD-45 Charlyn steering troubleshooting?

Hello,

Does anyone have a book or ideas on how to troubleshoot the heavy-duty WD-45 Charlyn power steering system. Is there even a more detailed 'shop manual' than the typical A/C or Jensen manual??

My Dad's WD-45 has never had good steering, but it's completely dead...
We've replaced the pump, freed up the shuttle valve (amazed it only moves that little bit, like 1/8" each way, looking at control shaft eccentric).

We've opened up the big steering gearbox, too, all seems free and the bearings is good shape.
Still absolutely NO sense of power-assist at all.

Right now, we're putting in a pressure gauge to verify pressure, but think the pump is fine.

Any ideas welcome.

I can't help you but Steiners has a manual for Charlyn power steering. It says it cover the different models and tractors that Charlyn power steering was used on. Just an idea!
