1986 onan 6.5 generator nh-3cr/16020k

Can someone point me in the right direction to down load a service and operation manual. Also I cannot find an oil filter on this thing. Were there some older models that did not have them?

It runs great and operates super. I want to keep it that way.

Thanks
Jack

The numbers for my '83 gen set are: Oil Filter, Onan # 122-0800, Napa # 1762.
Air filter, Onan #140-0495, Napa # 2371. Hope that is some help, I doubt those
gen sets changed that much. M
