73. Using a drill press, secure the
supercharger pulley so that it is clamped evenly
and drill a 3/16” hole, 1.05” deep in the center
of the end of the pulley. Next, using a 1/8” drill
bit, drill a hole completely through the pulley
and shaft in the same position. This will allow
you to remove the pin if you are ever replacing
or removing the pulley.
NOTE: LPE recommends using a hardened
solid carbide drill bit for pinning the pulley.
74. Notice the pulley is clamped evenly, the
end is flush with the bearing rod, and the hole is
drilled in the center of the end of the pulley.
75. Place the 3/16” x 1” LPE dowel pin (part
# 98381A510 ) into the hole that was just drilled
out.
76. Secure the front cover and supercharger
pulley. Using a hammer and punch, hit the two
surfaces around the pin shown to the left. This
will keep the dowel pin securely in place.
