Wanted to share with all of you our PTO (Power Take Off) findings. Most of us know that the splines wear out about 30,000 miles for some coaches. Our 2008 Inspire 360 (Cummins ISL 425 and Allison with the Eaton pump) is at 49,500 miles. We are having Kevin Waite do annual service for us. Decided to check the PTO and found it only had one fluid line to it. This means it did not have the wet kit upgrade. We ordered the wet kit ahead of time and asked for it to be installed. Once Kevin and Brian opened the PTO up, we found a well greased spline with no wear. I have no evidence or knowledge that it was taken apart and greased at some point before I owned the coach. I purchased the coach in 2010, so not likely it was greased before I owned it. We are having the wet kit installed anyway.

Wanted to share some photos in case this helps others determine status of their 2008+ PTO as I know there is discussion on the topic from time to time.

You have a power take off?

Mel,
The PTO on the transmission powers a hydraulic pump for the radiator cooling fans and the power steering. It is the standard setup on later Country Coaches.

I'm going to validate exactly what it powers by following the hoses when I get the coach back... but I think you are right Peralko. However, it is just one pump, the Eaton pump in blue paint in the photos. Other photos I saw on John Davis' RV site stacked the fan and steering pump (two pumps for pre-2008 coaches?). So I'm wondering if I have another pump for steering attached to the engine.

Pretty sure you only have one pump. We have an engine-mounted pump that does the same thing as the pump on the PTO on later coaches. We had the hose from the pump burst a couple of years ago. Amazingly, you can still steer without power steering, but on the first hill, the engine shut down.
