Default Onan 4.0 Generator service repair manual help

I am making an attempt to restore a 40cc-1 R/6000p ? Serial# 0172363164.

I think it came out of an RV and I need to trouble shoot this unit for a rebuild.
Any help would be appreciated. Thanks, Bill

Could it be 4.0cck 1R/60000P

If in fact that is the code. I believe it would be made Jan 72 4000 watt 120v single phase 2 wire . With remote start ability. Confirm and somebody can get you a manual. Post a picture if plate is unreadable.

Be careful, Bill, and don't cut yourself while working on the Onan and get some of the green paint in your blood. I'm up to 5 Onan's now!

Thanks guys found the info.

Max, Thanks I found the cck thread sorry for being a pain.

MBB, You hit the nail on the head.

Dave, Too Late. Even have it mounted on a small
Foldup Trailer. Might even paint it green to match.

Cleaned the carb, installed new kit, sand blasted the intake, changed all manifold gaskets. Had to clean up corrosion on relay. Now have power
to the fuel pump and starter motor. Pump turns on, but not getting any suction from pump.
Pump will be the next project. Shot a little fuel down the carb and it fired
Right up. Hoping to not have to pull the heads yet. Electronics are a real
Challenge. What a dinosaur. might need some more help as I go.

Installed a new fuel pump. pumps 1.5-2. Starts and runs rough. Will install
new exhaust and hook up the autochoke tomorrow. Might need to pull the heads and have head work done. When I changed the oil it showed signs of
moisture in the oil it had a bad color. I suspect this unit has been sitting for a while. The wiring is a real beast. I have read the thread on changing points to EI and will probably be going that in the near future. Thanks for the help and
I will keep posting.
