Hydraulic fan motors are a complicated subject. The original motors were built by several different companies. Two same-model coaches built in the same month can have completely different fan motors. Some fan motors can be rebuilt, or resealed - some can't because parts are no longer available. A fan motor can seep oil for a long time before it becomes a problem...the original motors on our coach have 180,000 miles on them. They seep a little, but don't drip oil, and still work fine. I watch them, but will not worry about them unless they get much worse. It is up to the coach owner, or his mechanic, to decide when a fan motor must be rebuilt or replaced. Replacement can be expensive. $$$$
Here is a thread that may give you a better idea what you might have to deal with, if a fan motor becomes a "problem".
