Hey guys I just bought an Ingersoll 4120 with a bad p220 in it. I have an onan gen set. The gen set is a marquis 5500 made in 98 I believe. I know I have to take 5 of the governor balls out to make 3600 rpm. My biggest question with this swap is does anybody know what hp this new motor would make? The model number on the motor is 5.5 BGM-FA/26105H if that helps.
Thanks for the reply Boomer. I tore down the original motor tonight and it looks like the flyballs spacer will fit right in the cam gear of the gen set. I figured as long as the flywheel will interchange the other end of the crank just has a fan bolted to it. Should be simple to fab that up. I will shoot you an email to get those manuals. Thanks
