4040 Flywheel/Ring Gear Seperation Help!

Recommended Posts

Wendy
Hi, The ring gear in my 4040 seperated from the flywheel during a backfire episode in winter. Pressed back together, came apart again. Pressed together again w/ PJ Weld, which held for about 10 starts, blew apart again. Anybody got a solution? Fit requires C clamps to assemble, pretty tight. New flywheels not available. Is it possible to weld steel/allow? Thanks for the Help, George HOlmes

On an automotive flywheel and ring gear I have put the flywheel in the freezer and the ring gear in boiling water or heated with a torch then put in place. after the ring gear cools off and the flywheel warms up I then tack welded in three or four spots.

Oops, submitted too soon....thought I might try drilling and tapping horizontally at the juncture of the steel and alloy. That would brace the connection a couple of ways. Maybe with supper loctite it would hold. Not sure I can drill effectively into one soft and onehard material, but it's worth a try, all else failing. Thanks again, George H

      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
