Default Onan 4.0 BFA-50DR/22541C manuals

I have an Onan 4.0 BFA-50DR/22541C S/N B873187823 that is installed in a bucket van. Besides generating 3phase it (mechanically) runs the hydraulic pump. (Fuel from vehicle tank and battery is vehicle battery)

I've read many forum posts giving links to manuals over at

but that website has been non-responsive for days for me (I just get a time-out every time I try to access).

I have found a few pages here and there in some posts (THANK YOU! - at least got me running), and have also seen members emailing them occasionally upon request? jonriegel AT gmail com

I believe I'm looking for 965-0262 (parts) and 900-0337 (service) and 965-0122 (owners) manuals?

The vehicle sat in a junkyard for a few years, but generator started right up, and we have been using it 4 days a week for a year. We have done a few field-repairs & basic maintenance in the last month, but now it's time to catch up on "real" maintenance.

Thank you,
