Oil Seals

Place rotor on rubber pad or cloth. Install oil seal springs in their respective grooves on rotors, with each edge of spring fitted in stopper hole. Ensure oil seal springs have been painted in cream or blue color: cream colored springs must be placed on front faces of both rotors and blue springs on rear faces of rotors. When installing, painted side of spring must face oil seal (upward), Fig 1.
Insert new "O" ring in each oil seal. Install inner oil seal to each side of rotor as follows: Position oil seal to groove so square edge of spring fits in stopper notch of oil seal. Press into position by using a used inner oil seal so lip of inner oil seal sinks into position approximately 0.016" (0.4 mm) below surface of rotor.
