1. Cover the 4 oil paths of the cam journal with vinyl tape as shown in the illustration.
   

   УКАЗАНИЕ:

   There are 4 oil paths in the groove of the camshaft. Plug three of the paths with pieces of rubber.

2. Prick a hole in the tape placed on the advance side. Prick a hole in the tape placed on the retard side path, on the opposite side to that of the advance side path, as shown in the illustration.
   





3. While applying approximately 150 kPa (2.0 kgf/cm², 22 psi) of air pressure to the oil paths, forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).
   

   ПРЕДОСТЕРЕЖЕНИЕ:
