Replacing a Onan 4.0, same model, How hard is it?
I got it off the internet, I can handle the weight, and my generator is mounter on sliders. How difficult is to remove the old and install the new one?

It should be fairly straightforward, though it may take a bit of time and effort. The fuel and AC power connections require removing the starter solenoid, voltage regulator, control module, and the switch/fuse/circuit breaker panel piece in the generator (all of which can be done through the usual access panel on the generator).
What? I've never had to do that- the set comes with the 120 volt leads in place, the fuel connection is external and the battery connections are right up front- ground on the outside, positive is the starting solenoid.
Maybe they've changed it since mine was built, or maybe I was just dealing with a less than helpful original installation, but I think that's what I had to do to drop mine. The DC connections were as you described. I think the fuel connection was inside the generator, though I could be remembering that part incorrectly. I know I pulled the 120V connections from inside the generator. It could be that they were going through an Onan-supplied flex and I just couldn't get at the other end very easily in my particular installation; I didn't study it to see whose flex 120V connection it originally was.
Regardless, it's not problematic in any case.
