ive belt length by observing belt wear
indicator marks on side of tensioner.
1. Pointer at this mark, indicates minimum new belt length.
2. Pointer at this mark, indicates maximum new belt length.
3. Pointer at this mark, indi cates belt must be renewed.
3. R
emove drive belt from supercharger.
F
it 1/2 inch square drive ratchet or bar into square
aperture on front face of tensioner. Using bar, turn
tensioner assembly to the right (viewed from front)
against spring tension.
Wh
ilst holding the tensione
r against spring tension,
remove drive belt fr om tensioner pulley. Release tensioner
slowly and remove bar.
D
isconnect belt from
other pulleys and remove it from rear
of tensioner.
1. NOTE: Ensure that belt is correctly and squarely located on
each pulley. Check belt wear indicator marks to confirm that drive
belt is within limits.
Installation is a reversal of the removal procedure.
