Onan Gen 10K filters

I have an Onan 10K generator model HDKCA (or B) Spec Letter F that I'm having difficulty finding the part numbers for the oil, fuel, and air filters.

I went to the Onan web page and with my model number, the Spec Letter only goes up to "E". Not sure if that model would be the same as mine.

I have no info on part numbers in my owner's manual nor the Generator's Operator's manual.

Any info would be greatly appreciated.

  • Isn't it great when a mfg (Onan in this case) thinks of their future owners? When you look inside of the MH's cupboards or closets where they put all of the paint colors (and mostly other useless info) wouldn't it be nice if they put in a list of all the engine filter #s?

  • Bill, you're absolutely correct. Pulled out the generator and right there on the front/side is a tag with all the filter info. Never crossed my mind to look on the generator itself. thanks.

    Twomed...thanks for the info, but my generator is a Spec F...not A. Not sure if the NAPA numbers will cross reference to the Onan numbers on the generator. Will check.

  • Twomed I do not own an Onan but may I extend a cyber handshake for a superb information loaded losting?

  • If you're where the MH is, check the front of the generator. I don't know about the 10kw, but on the 7.5, Onan put the P/Ns right there on the front of the generator. One of them has since been superseded, but it will get you going in the right direction.
