Make sure the pin alignment hole (1) is correctly aligned with the alignment hole (2) in the lever before pushing the roller pin into the cam follower lever. Cam followers can be checked for correct roller pin in- stallation by using a 5/64-inch drill bit. If the drill bit enters 10.2 mm [0.40 inch] the roller pin is installed correctly. If the drill bit enters only 5.1 mm [0.20 inch] or goes in 18.0 mm [0.70 inch] the roller pin is installed incorrectly. Roller pins that are not installed correctly must be removed and new roller pins installed. Turn the roller by hand to make sure it rotates freely.
