10. SUPERCHARGER BELT TENSIONER ADJUSTMENT

A. Make sure that the 1/2-20 jam lock nut previously

threaded onto the tensioner arbor is threaded

down almost all of the way, but not tight. The belt

is tightened/loosened by rotating the belt tensioner

adjustment screw. Tighten the belt until light

resistance is felt in the belt tensioner adjustment

screw. Proper belt tension is achieved when the

belt can be twisted approximately 1/4 of a turn by

hand. Adjust belt tension as needed. Do not over

tension the belt.

B. From beneath the vehicle, tighten the 1/2-20 jam

lock nut on the belt tensioner arbor.

C. Reinstall the factory accessory belt using the

factory routing.

A. Separate the air pump inlet hose from the factory

hose union that was originally connected to the

engine inlet duct.

B. Insert the supplied 3/4" air pump inlet hose filter

into the pump inlet hose. (See
