I think Forest has got this one right. The hydraulic fluid gets hot and the heat exchangers near the axle and their electric fans are used to remove excess heat from the fluid. It's a pretty nasty location under there for those fans, but when I tested mine they worked. I really have no idea if they cycle on during normal operation, but I would assume they do. Russ

Call Chuck Clarke in parts at Newell. He should be able to get you the part #.
Just found the picture I took when Newell replaced the compressor.
Hope this helps.
I think Chester Stone has either found a replacement or was able to get his repaired.
We'll be back to Paincourtville in about a week. Let's get together to see coaches.
MPBCR, I purchased a Dayton motor, # (1) 3LU73J. I cannot find the purchase invoice but I think it was Graingers. These motors come with a shaft that is extra long and has to be cut to fit the application. I still have the new motor since I was able to have my original rebuilt for small sum. All it needed was new bushings. I took a few photos showing how I got the motor out of the unit and will post them if you are doing the work yourself and would find them useful.
