My 1990 CC has a 15Kw Onan Genset. Not on a slide and it seems to work well. And that is what I want it to keep doing. In preparing for our trip to OKC then into Colorado I was going over the GenSet. Oil change, fuel filter and air filter change all covered. Then I thought I would check the belt. Got the shroud off ok, and low and behold, while it looks pretty good, it does have a small crack or two just starting to be noticeable. Does anyone have a good source for Onan "Stuff" as the closest location is Springfield, MO and they seem somewhat confused. I have serial & model number, they seem to think it is a 3 cylinder set up and are having problems with replacement filters/etc. The ones I used are from the stock (last of em) left on bus when I purchased it. I will check NAPA tomarrow, but am holding my breathe. Uh, Jon, got an extra belt?
