Product review (5 stars): Wrong Part Name...
Manufacturer and part number are a match for the picture, but description/name is wrong. It should read "Idler Belt Arm Right Hand (when facing the  machine from behind)" or according to the documentation included with the machine "TORQUE ARM, RIGHT SIDE (FROM REAR)". Other than that it is a match for  a SaniServ 501 ("A5011P" to be exact, but good luck trying to find parts using this number) Ice Cream Machine.

  If you're looking for the one on the left it should be SANISERV 103248 "TORQUE ARM, LEFT SIDE (FROM REAR)" or Idler Arm. Because they are slightly different, this one cannot be installed on the right side due to an extra perforated lip for the spring tensioner.
  Hope this helps someone.
