🔧 Enhance Your Onan RV Generator Performance with GPS GENERATOR PARTS SPECIALIST Tune Up Kit for Model KY 4000, Spec A-R Review

Be careful! It's more my fault for not reading the COMPLETE description. The service kit does not include oil like any other site. Without them the set is incomplete.

This kit is for Mfg's 4kW Onan Generator. All parts are good, I just had to rebuild the spark plug to Mfg's specs. All the details fit well. I will order again as Revain is an excellent value dealer for these onan parts.

I bought this DIY kit but found I don't have access to the air filter, fuel filter and spark plug. I had to bring my RV to Onan/Cummings for service as my generator had to be offloaded with a forklift and removed from the RV. ;-(

Luckily I found an instruction manual online with instructions. Replacing it was the hard part. I didn't rate the individual pieces so I'm not sure of the value of the piece. The kit was easy to buy without wasting time looking for all the parts.

Great little kit for servicing my Onan 4000 gas generator.

I was confused because it doesn't have an oil filter, but these generators don't have oil filters (learned a few new things). There you will find a nice chart to help you select the correct weight of oil for your operating temperature and a spark plug gap tool that is included. The air filter
