Exige S/C Page 10 Continue to idle the engine until normal running temperature is reached, then check the level on the dipstick (with 40 psi showing on the Accusump gauge) as detailed above. Top up the oil to the top mark on the dipstick. Supercharger Remove/Refit To remove: 1. Remove the chargecooler together with inlet and outlet 'U' shaped ducts. 2. Remove the throttle body and vacuum/breather hose plumbing. 3. Using a 6-point socket, relieve auxiliary belt tension and remove the auxiliary belt. Remove the alternator top mounting bolt, slacken the lower, and swing down the alternator. Release the dipstick tube from the supercharger. 4. Using a strap wrench, remove the supercharger pulley retaining nut, and slide off the pulley. 5. Remove the support strut between the throttle body adaptor and the clutch slave cylinder. Slacken the pinch bolt securing the supercharger to the nose bracket. Remove the two bolts supporting the super- charger to the inlet manifold and withdraw the supercharger. To refit: 1. With the supercharger nose bracket bolted to the engine mounting plinth, fit the upper fixing on the alter- nator to the nose bracket outer end (with 13.5mm spacer). This defines the position of the nose bracket. Tighten bracket to engine mounting plinth to 50 Nm. Remove alternator top bolt and swing down to allow supercharger to be fitted. 2. Prepare supercharger: Clean mating faces of supercharger and outlet adaptor using Betaclean 3900. Fit 'O' ring into groove in outlet adaptor and fit to supercharger using 6 off M8 x 25 setscrews with Permabond A130. On the fixing located inside the adaptor, Permabond should be applied over the entire thread length. Orientate the adaptor with the outlet pointing towards the rear of the car when fitted. Torque tighten all fixings to 25 Nm.
Clean mating faces of outlet adaptor and outlet elbow using Betaclean 3900. Fit 'O' ring into groove in outlet adaptor face. Fit outlet elbow to point to LH side of car using 4 off M8 x 25 setscrews with a pipe clip bracket secured by both rearmost fixings. Tighten to 25 Nm. 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. |
