      What's wrong with the one currently on the unit?

      For parts, member onanparts.com (TJ) http://onanparts.com/ can get you any and all parts for that P216G that you'll need for a rebuild.

      Mind saying where your location is?

        It's a long story, but I bought it at an auction last year and it ran fine, but a little funny. This year it stopped running so I took the motor apart, and someone had blocked off the intake and exhaust ports to make it a single cylinder. The right side piston exploded inside blowing out the head and bending the crank, somehow it still ran on one cylinder, all the piston parts were laying in the oil pan. So I don't think I will be able to rebuild it. I was wondering if i could buy a new one, or if i can put a different brand motor on it.

          The threaded crank is the kicker. It's a Miller exclusive. There was a seller that had a bunch available on ebay a while back (not there now) for an 18hp but that would require different rods too in addition to the new piston(s) and everything else.

          You could give a call to member weldersales (Larry Burross) of Applied Equipment in Dallas who may have a used unit available or know the whereabouts of one.

              Maybe you could use a different engine and have someone make an adaptor between the crank and the gen thats threaded. Just my thoughts...Bob

                Definately not going to say it isn't possible but as the almost 3" crank stub screws into the rotor and the rotor butts almost right up to the seal area, a crank adapter would require spacing the stator housing away from the engine several inches which, while doable, would present its own challenges.

                  I thought I saw bobcat retrofitted with a honda 20 horse v twin

                  Hello guys, I recall seeing a bobcat retrofitted with a Honda V twin in the 18 to 20 hp range, I cant recall which it was exactly. The stock Onan pooped out and the guy had an adaptor collar made somewhere because he wanted to get the Honda reliability. I remember it was an older unit that did not have the totally enclosed sheet metal and the engine was not covered. I know that a while back the Lincoln ranger 8 or 9 (not sure ) was offered with a Honda as well. Dunno if it crossed applications.
                  I have a welding addiction

                  ...the only stupid question is the one you didn't ask

                      Miller switched to the threaded crank in the mid-90s and the earlier Miller/Onans had a stubby tappered output and an adapter plate that would be easier for a re-power.

                      Yup, no doubt about it in my mind. Just saying the engine adapter-to-stator housing spacer would pose the biggest challenge for most people without access to right material and lathe or mill.

                          sometimes you can find lawn tactors with 16hp onans like johndeer...as long as you have a good crank you could swap out...might be somethin you could look into

                            If mine was still apart I'd get you some dims and drawings but I'm afraid it's staying together for now.

                              So you bought it an at auction sale- how cheap? If it was me I think I'd part it out or try to sell it "as is" to one of those above mentioned parts suppliers.
