Hanno Pump

[Lem and Christina Stevens]

Don,  Flipping over the flapper valve piece worked great.  I have set the engine back up on the bench, but have not had it in the air yet.  Thanks for the suggestion!  Lem

  You can also reverse (turn them over) the plastic flapper valves in the pump and it will correct some minor problems if you have overheated the engine and baked the pump which caused the valves to take a different shape.  Nothing to loose trying this if the pump doesn't work anyway..........   Just be very careful and inventory the pieces and positions as you take the pump apart.

    Nat, is the 1.40rx pump just set for a higher volume?  I wonder why Hobby Services didn't use some of the available pieces to repair it?  I bet that all I need is to replace the plastic piece that acts as the stopper valve. I am sure that the metal pieces are fine.

      Lem you may be able to repair the pump yourself. If not the OS140RX uses the same pump, about $150 m/l.

        Does anyone have an OS PD-05 pump they are willing to sell?  I have a Hanno 61 in a plane I just finished and the pump died.  Hobby Services does not sell parts for this pump anymore.  It is the later version of the Hanno that has one pump inlet and one pump outlet.

        Please email landcstevens at comcast.net

        Thanks,

        Lem
