1. You must remove the supercharger front
cover from the supercharger assembly to
change the pulley. This is because you must
support the shaft when pressing the new pulley
on or you will cause the shaft to move in the
cover housing and it will need to be rebuilt/
serviced.
Refer to the LPE pulley instructions for cover
removal.
2. Secure the front cover in a vise, being
careful not to damage the aluminum casting.
3. Unscrew the primary bolt from the pulley
removal tool until the tip of the bolt is just
sticking past the inside of the tool.
4. Place the pulley removal tool over the
back of the supercharger pulley and hand
tighten the bolt so that the bolt is pressing
against the center of the shaft.
NOTE - make sure you are pulling on the pulley
against the shaft and NOT against the casting
or you will move the shaft in relation to the shaft
support bearings.
