7. Use a 3/8” long-handle ratchet to rotate the dynamic tensioner counterclockwise to remove the supercharger drive belt from the supercharger pulley. It is not necessary to remove the belt from the vehicle completely.
8. Refer to Figure 4 on the next page and disconnect the following from the supercharger assembly:
10. Remove the two VSV rack nuts and lay the rack to one side.
11. Unplug the connectors from the throttle position sensor (Arrow A, Figure 5) and the idle air control valve (Arrow B, Figure 5).
12. Unplug the connectors from the EGR position sensor and the EGR gas temperature sensor on the EGR valve.
13. Remove the two bolts and two nuts from the throttle body (Figure 6). Remove the throttle body from the supercharger intake plenum and set it aside.
NOTE: Do not disconnect any cables.
14. Disconnect the EGR pipe and valve from the supercharger manifold.
1. Use the pattern in Figure 10 to remove the nose drive attachment bolts.
2. Place the supercharger over a drain pan to catch the oil as the nose drive is removed.
3. Use a soft rubber mallet to gently tap on perimeter edge of the nose drive to loosen the gasket seal. Use gradual back and forth motions to pull the nose drive assembly from the supercharger.
4. Remove the Phenolic block from the supercharger gear by pulling it straight off of the attachment pins (Figure 11).
5. Wipe the gasket-sealing surface clean and remove all debris.
CAUTION: Avoid contaminating the supercharger gear housing with any debris.
6. Insert the new Phenolic block over the attachment pins.
CAUTION: Insert the attachment pins only into the holes with flanged openings (Arrows, Figure 12).These flanges must touch the surface of the drive gear.
7. Press the Phenolic block until it seats against the gear.
8. Spread the TRD-supplied Locktitetm Gasket Eliminator Sealant to the sealing surface of the nose drive assembly (Figure 13).
9. Align the nose drive gear pins (Figure 13) to the holes with flanged openings on the Phenolic block (refer to Figure 12) and press the block into position (Figure 14).
10. Replace the 7 bolts removed in Step 1 on Page 7. Use the pattern in Figure 10 to tighten the drive assembly evenly. Torque the bolts to 20 ft-lbs.
11. Tilt the supercharger assembly up but be careful not to damage the boost actuator. Use a 3/16” Allen wrench to remove the fill plug (see Figure 15).
12. Fill the reservoir with the supplied fluid (Figure 15). Use all of the oil provided (100 ml).
13. Install the new fill plug.
Section IV – Supercharger Installation
1. Remove the cover from the engine. Make sure the gasket is properly placed and no hoses or wires are in the way.
2. Attach the ground wires to the drive assembly and install the bolt (Figure 16). Torque the bolt to 20 ft-lbs.
3. Install the PCV valve hose to the supercharger assembly and put it in place on the engine (Figure 17). Install the two bolts and two nuts removed in Step 20 on Page 6 but leave them finger tight at this time.
4. Attach the ground wire to the back of the supercharger (Arrow A, Figure 18). Torque the bolt to 12 ft-lbs.
5. Attach the passenger’s side engine hanger to the back of the supercharger (Arrow B, Figure 18).Leave the bolt finger tight at this time.
6. On the driver’s side, install the chamber stay over the stud and collar using the washer and locknut (Figure 19). Leave finger tight at this time.
7. Torque the supercharger nuts and bolts to 32 ft-lbs. Torque the passenger’s side engine hanger to 29 ft-lbs and install the power steering line onto the stud (Circle, Figure 18). Torque the nut to 69 in-lbs. Torque the driver’s side chamber stay to 14 ft-lbs.
8. Install the EGR valve and gasket on the supercharger assembly (Figure 20). Leave the bolts finger tight at this time.
9. Connect the EGR pipe and gasket to the EGR valve. Torque the EGR valve and pipe bolts to 9 ft-lbs.
10. Install the brake servo vacuum hose to the fitting on the air intake chamber (Figure 21).
11. Place the throttle body and gasket. Install the EGR gas temperature bracket with the two nuts and two bolts (Figure 22). Torque the hardware to 14 ft-lbs.
12. Plug in the connectors to the throttle position sensor (Arrow A, Figure 23) and the idle air control valve (Arrow B, Figure 23).
13. Plug in the connectors to the EGR gas temperature sensor and the EGR position sensor.
14. Install the VSV rack.
15. Reattach the spark plug wire loom.
16. Use Figure 4 on Page 4 to reconnect the remaining hoses.
17. Use a 3/8” long-handle ratchet to rotate the dynamic tensioner counterclockwise to replace the supercharger drive belt over the supercharger pulley.
18. Install the throttle body air intake tube and tighten the clamps (A Arrows, Figure 24).
19. Connect the vent hose to the cam cover (Arrow B, Figure 3).
20. Use the diagrams made in Step 2 on Page 2 to connect and check all vacuum hoses, cables and brackets.
21. Reconnect the negative battery cable.
22. Start the engine and check for leaks.
22. Solara only: Replace the strut tower brace. Torque the nuts to 59 ft-lbs.
