    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
  Gettings.

  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.

Here's the RD1C guide (at the end of the thread - my apologies! I thought
Outlook would automatically append replies sequentially)
