2. Check superch
arger dr
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.

C
harge Air Cooler System
Each cyl
inder bank is fitted with a charge air cooler unit wh
ich supplies pressurized air to the four cylinders via an adaptor
block. The inlet ports to the tw o charge air coolers are connected to the supercharger outlet by an inle t assembly consisting
of rubber ducts and clamp plates . An outlet stub at the rear of each charge air cooler unit provides the connection for the
by-pass valve airflow. The charge air coolers ar e water cooled via a radiator and coolant pump.
Charge Air Cooler Coolant System

Parts List
Each charge air cooler unit is a fin and tube air to liquid heat exchanger. The coolant circuit for the charge air coolers
consists of a pump, ra diator, connecting hoses and a bleed pipe.
