3. Fit M8 stud B111E6081S into RH top (as viewed on face) fixing position in supercharger inlet flange. Clean
mating face on supercharger and inlet adaptor using Betaclean 3900. Fit 'O' ring into groove in adaptor
face and fit adaptor to supercharger using 2 off M8 x 30 flange head bolts in top positions and M8 flange
nut on stud - all 25 Nm. Disregard 4th position at this stage.
4. Mount supercharger: With the pulley removed from the supercharger, slide the nose into the nose bracket
until hard against the machined step. Support to the inlet manifold sliding bushes using M10 x 50 flange
head bolts and Permabond A130, but do not tighten. Tighten the nose bracket socket head pinch bolt to
25 Nm.
5. Loosley fit the supercharger support strut between the inlet adaptor (M8 x 55 bolt with A130) and the clutch
slave cylinder fixings (M8 x 25 with A130). Tighten the three support strut bolts to 25 Nm. Carefully tighten
the two M10 x 50 flange head bolts to pull in the two spacers evenly to clamp against the supercharger.
6. Refit the alternator upper bolt and spacer and tighten to 25 Nm. Tighten the lower bolt to 25 Nm.
7. Fit the pulley to the supercharger with the longer boss towards the 'charger. Fit the nut onto the shaft, and
use a strap wrench to hold the pulley whilst the nut is tightened to 61 Nm.
8. Use a 6-point socket on the tensioner arm to allow fitment of the multirib accessory drive belt around the
pulleys as shown, ensuring that the belt is correctly seated in all the ribbed pulleys.
9. Refit other components in reverse order to removal.
Note areas of change compared with standard models;
# Engine dipstick tube altered to avoid supercharger.
# Crankcase breather pipe altered to avoid supercharger.
