Hi All,  For the absolute best information on properly rebuilding
the Ampico rotary pump, buy Craig Brougher's video, "Correct Method
for Rebuilding The Ampico Vacuum Pump".  It's available directly
from Mr. Brougher, visit

  http://www.player-care.com/video_2.html

Musically,

John A. Tuttle

 [ The web page says about the videocassette: "This is a 2 hour video
 [ that is thorough and complete, covering all three Ampico pump systems
 [ (Ampico pumps, Stoddard and model A, the interim transition model A,
 [ and the model B.)  No aspect of the Ampico pump is taken for granted
 [ or excluded.  The pump you watch being rebuilt is then also tested,
 [ and you will see its output and hear its normal sound, with and
 [ without the hatch cover.  There will never again be a reason to
 [ rebuild the Ampico pump and "hope" that it will turn out all right."
