Jim, Cummins owns Onan or vice-versa. You should be able to find a Cummins dealer locally. I got some parts from Cummins Jacksonville one time when we on the road moving a boat. They have several lacations, some are down in the middle of the state.

And dig real deep in your pockets --Onan replacement part prices are EXORBITANT !!!!! Your gonna need the title to your car ,pick of the litter and your first born to buy even the smallest part!!!! My experience it was cheaper to buy a non running gen and take off the part I needed---- it was a small carb choke spring and choke plate and then turn around and sell the gen for what I paid for it!!! ended up getting the parts for free---FED 387

Onan 10K Diesel Generator. What (in hours) is the lifespan of these units / when do they get to the point where they start having the kind of problems. Where its better to replace the unit rather than fix it? Just asking out of curosiusity as mine only has around 1200 hours on it. For future reference.
Thanks

I have seen them with 20,000 hours on them. Most need fairly expensive generator related parts around 10,000 hours. New ones are $10,500 so fixing them is a good idea.

Engines are good for as long as you take care of them.

I have not seen any Onan Diesel RV units with more than about 8-10 thousand hours myself. They generally don't get used anywhere near that many hours for most owners. Yes the generator ends will likely need parts or repairs more than the engines. If you service the engine regularly and do preventative maintenance it will usually not fail. I have seen deterioration of the generator ends from weathering and just age. Engines are Kubotas or Isuzus and very reliable. 8-10-12 kw Onans are very good units and give thousands of hours of service.
