78. Install the cover onto the supercharger
assembly. The three pins sticking out of the
supercharger drive shaft in the front cover
go into the three holes in the plastic coupler
that are not occupied by the pins from the
supercharger assembly.
79. Install the six (6) cover bolts with a 10
mm socket and extension. Torque to 27 Nm
(20 lb ft). The torque sequence is not critical
on this component. With the plastic cover
removed from the end of the shaft, tap the
end of the shaft with a rubber mallet to seat
the plastic shaft coupler. Check to make sure
the supercharger assembly turns smoothly. If
it doesn’t turn freely, tap the end of the shaft
again to fully seat the plastic coupler.
80. Re-install the throttle body gasket that you
removed from the front cover.
77. Apply a thin film of the supplied Permatex
Ultra Black Gasket Maker to the LS9 cover
flange surface.
