Check with James @FOT for the correct fan speed for your coach. Actually I have a hand written fan speed sheet he sent me. (attached below)

Ken,
 Thanks for posting the fan speeds etc.
I think if we had the engineering info on the pumps and motors (Flow rates, HP, torque etc.) we would be able to find suitable replacements. Hydraulic pumps and motors are pretty common industrial items available just about anywhere. Custom built items in this system is nonsense.

Yes, many later generation solutions for the hydraulic fans with a lot of advantages to infinitely variable speeds, enhanced fan control, efficiency. The problem is, this is a pretty big ticket item for preventative maintenance so most people hope for the best with what they got. 

David, be sure and retain your old parts.  Sometimes the parts are rebuildable, you can maybe recover some of your cost by reselling the hard to find motors.

They say we will be on the road again tomorrow - sometime. Somehow someone here goofed when they ordered parts and ordered only one fan motor, and I need two. The second one is being overnighted (at their expense) tonight and will be here in the morning. It seems that the rear fan motor seized up somehow and that blew out the original pump and speed switch. I asked about the old parts, and they were just going to toss them in the dumpster, so I asked to have them. I got a PM from a forum member asking for them, so I got them for him.

Cabin Diesel in Big Cabin, OK is great to work with. They provided me with a printed estimate prior to starting work. When they realized their mistake today (only one fan motor and two were needed) they got on the phone to Nac to get the second one. They then printed a second "estimate" to show me what it should have cost, and then a third one showing what it will actually cost after they adjusted some prices. Their campground is pretty basic, just a few pull-through spots with full hook-ups. The price reflects that and then they offer discounts. Other forum members know more about what there is to see and do here, but this is a decent overnight spot.
