I have good news, the pump had been changed out of my 09 Nimbus before I bought it. However, to my knowledge the unit has never been greased ( 4 years ago ).  So the questions are, about where is this pump located and what kind of grease should I use ?.

Thanks for your help.

The pump is mounted to the side of the transmission on the passenger side of the coach. I do not know what type of grease or how much would be needed, as on the Country Coaches I changed out had the wet kit installed on them, so no grease needed. They have a line from the transmission to the pto assembly that flows trans fluid through the pto

Look for some type of "spline grease" or "coupling grease". It's pretty sticky stuff.

     Drove the coach today for the first time since the pump mess . All is well , A-men .  Here is what I notice . The fan does not scream  at high speed, guess what --- that is  what it should have done all along but it screamed wide open  since day one  . It is a two speed pump and should run at low speed until engine heat requires more fan speed . The bite in all this is --Why didn't the shop folks say something to me about it not being correct --??? It now runs slow speed , keeps the temp at 180 to 185 at 65 MPH in 80 degree temp . Have been told that if something is wrong with the pump it will run wide open fast . Have been told if you have a pump problem to unplug the wires from the control (rounded) box on the on the pump and it will run at full fast speed .  I feel "not good about this being a preventable thing" I will shut up for now  .      Brad Metzger
