In between all the other details in my current project, I rebuilt the fan motors and wanted to pass along some details. My fan motors are Saur Sundstrand 551101142183 (need this # for any tech support). Foretravel # (not good anywhere but FT): P36583 and P36584 (has valve attached to bottom). The seal kit is 221.20.034OK and it includes the shaft seal. Turolla in Ames, IA,, a division of Danfoss is where you need to go for tech support (515) 239-6677 and they will direct you to Berendsen Fluid Power (800) 722-4975 for the seal kit.
Torque for 4 housing bolts is 45#. The shaft nut is 32-41# They didn't have torque specs. for the fan blade bolts, but I don't think that is critical as long as you tighten them evenly.
I took notes as I did the rebuild and will do a write up soon and I will be happy to attach it to an email - I need to make sure everything was done right and it works before doing so.
I'm about done prepping the chassis, rear engine area, etc. and should be priming and painting this week end. I hope the make the Calif. rally on the 4th.
I didn't see a write up and as I was told by the a tech inspecting my RV that I have a hydraulic leak near my fan motors that write up might come in handy :D
