52. 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.
53. Clean the mounting surface of the
supercharger with a razor blade and Scotch
pads. Replace the factory isolator coupling with
the LPE solid supercharger isolator coupling
(LPE part # L960130709).
54. Notice the unoccupied holes on the
coupler. That is where the dowel pins from the
supercharger front cover will go. The pins on
the supercharger cover shaft will go into these
holes.
51. Place the 3/16” x 1” LPE dowel pin (part
# 98381A510 ) into the hole that was just drilled
out.
