Onan replacement engines

Recommended Posts

Tuffy: They are V twins,I am in process of 24HP Honda transpant at this time. I went with the 1 1/8 shaft and a new clutch from Warner, 175 ft lb. Got the engine & muffler from Small Engine Warehouse, clutch from J Thomas & machined my own flywheel adaptor. This is going in a 9020. Also redoing another 9020 at the same time so have two frames ready to start assembly on. Second one will be original Onan. Should have a good start at it before weekend is over. StanD

Briggs made an opposed twin up either 19 or 20 HP in either vertical or horizontal crankshafts. I don't see them in the 2003 engine catalog other then out of production models. From what I can see it's all V twins now. Some of that might be to more stringient emission standards and the flat or "L" head engines couldn't cut it in that size.

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
