  Does anyone have a rd1c installation guide or advice. I
want to   check before bolting the psru back up for engine runs.
Wasn't there a viton seal recommended to seal the bearing/thrust
washer stack against the motor mount plate?    Alex Molteno
Yes but I recommend Teflon.   Paul Lamar


I will see if I can
dig up my RD 1C manual and email it to you directly.   Scott

Alex,                   The teflon disc goes between the
input gear and the inner surface of the planetry reduction to stop
metal to metal when you pull power and the input shaft can be drug
forwards.  The prop shaft goes through the center of the teflon disc.
Bearings go against the plate, and make sure you have a low pressure
seal in the plate. A low pressure seal has one lip only, a high
pressure, two or double lip.  Little pressure in the housing so the
low pressure seal does a much better job of sealing as is more
flexible.
