    Toyota Supra MKIV

    Bekannt aus dem Fast & Furious Film, kam im Juli 1993 die vierte und bisher letzte Generation des Toyota Supra auf den Markt. International wird dieser Typ "Supra MKIV" genannt.

    Toyota Supra MKIII

    Anfang 1986 wurde die dritte Generation des Supra vorgestellt. Sie ist zugleich die erste, die nicht mehr mit dem Namenszusatz Celica vermarktet wurde.

    Celica Supra (MK2)

    Die zweite Generation wurde im Herbst 1981 präsentiert und hatte mit dem neuen (170 PS) starken 6-Zylinder-Motoren einen komplett eigenständigen Antrieb.

    2000GT & Supra MK1

    Der von Frühjahr 1978 bis Sommer 1981 gebaute erste Supra wurde noch als Spitzenversion der Celica zuerst in Japan und später in den USA angeboten.

    Repair Manual

    Valve clearance - 2JZ-GTE Engine - Toyota Supra A80

    
    Inspect and adjust the valve clearance when the engine is cold.
    1. Remove ignition coils assemblies (See page IG-6 )
    2. Disconnect engine wire protector from No.4 timing belt cover
      1. Disconnect the engine wire from the 4 wire clamps.
      2. Lift out the engine wire protector from the cylinder head covers.
    3. Disconnect engine wire protector from cowl top panel
      1. Remove the bolt, and disconnect the ground strap.
      2. Remove the 2 bolts, and lift up the engine wire protector.
    4. Remove IAC valve pipe
      1. Disconnect the 5 air hoses from the IAC valve pipe.
      2. Remove the IAC valve pipe from the pipe clamp on the No.1 cylinder head cover.
    5. Remove No.1 and No.2 cylinder head covers
      1. Disconnect the cruise control actuator cable from the cable bracket.
      2. Remove the bolt holding the VSV to the turbo outlet duct.
      3. Disconnect the 2 PCV hoses from the cylinder head covers.
      4. Remove the 6 bolts, 2 nuts, 8 seal washers, No.1 cylinder head cover and gasket.
      5. Remove the 6 bolts, 2 nuts, 8 seal washers, No.2 cylinder head cover and gasket.
    6. Set No.1 cylinder to TDC/compression
      1. Turn the crankshaft pulley, and align its groove with timing mark ”O” of the No.1 timing belt cover.
        Always turn the crankshaft clockwise.
      2. Check that the timing marks of the camshaft timing pulleys are aligned with the timing marks of the No.4 timing belt cover.
        If not, turn the crankshaft 1 revolution (360°).
    7. Inspect valve clearance
      1. Check only those valves indicated in the illustration.
        • Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
        • Record the valve clearance measurements of those that are out of specification. They will be used later to determine the required replacement adjusting shim.
        Valve clearance (Cold):
        • Intake 0.15 - 0.25 mm (0.006 - 0.010 in.)
        • Exhaust 0.25 - 0.35 mm (0.010 - 0.014 in.)
      2. Turn the crankshaft pulley 1 revolution (360°), and align the groove with timing mark ”O” of the No.1 timing belt cover.
      3. Check only the valves indicated as shown. Measure the valve clearance. (See procedure in step (a))
    8. Adjust valve clearance
      1. Remove the adjusting shim.
        • Turn the camshaft so that the cam lobe for the valve to be adjusted faces up.
        • Turn the valve lifter with a screwdriver so that the notches are perpendicular to the camshaft.
        • Using SST (A), hold the camshaft as shown in the illustration.
          SST 09248–55040 (09248–05410)
        • Using SST (A), press down the valve lifter and place SST (B) between the camshaft and valve lifter. Remove SST (A).
          SST 09248–55040 (09248–05410, 09248–05420)
          • Apply SST (B) at slight angle on the side marked with ”7”, at the position shown in the illustration.
          • Insert SST (B) gently from the inside as shown in the illustration.
          • Using a small screwdriver and a magnetic finger, remove the adjusting shim.
      2. Determine the replacement adjusting shim size according to the following Formula or Charts:
        • Using a micrometer, measure the thickness of the removed shim.
        • Calculate the thickness of a new shim so the valve clearance comes within specified value.
          T ......... Thickness of used shim
          A ......... Measured valve clearance
          N ......... Thickness of new shim
          Intake
          N = T + (A - 0.20 mm (0.008 in.))
          Exhaust
          N = T + (A - 0.30 mm (0.012 in.))
        • Select a new shim with a thickness as close as possible to the calculated values.
        Shims are available in 17 sizes in increments of 0.050 mm (0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299 in.).
      3. Install a new adjusting shim.
        • Place a new adjusting shim on the valve lifter, with imprinted numbers facing down.
        • Press down the valve lifter with SST (A), and remove SST (B).
          SST 09248–55040
      4. Recheck the valve clearance.
    9. Reinstall No.1 and No.2 cylinder head covers
      1. Remove any old packing (FIPG) material.
      2. Apply seal packing to the cylinder head as shown in the illustration.
        Seal packing:
        Part No. 08826-00080 or equivalent
      3. Install the gaskets to the No.1 and No.2 cylinder head covers.
      4. Install the 12 seal washers to the bolts.
      5. Install the No.2 cylinder head cover with the 6 bolts, 4 seal washers and 4 nuts..
        Torque: 5.4 N·m (55 kgf·cm, 48 in.·lbf)
      6. Install the No.1 cylinder head cover with the 6 bolts, 4 seal washers and 4 nuts..
        Torque: 5.4 N·m (55 kgf·cm, 48 in.·lbf)
      7. Connect the 2 PCV hoses to the cylinder head covers.
      8. Install the bolt holding the VSV to the turbo outlet duct.
      9. Connect the cruise control actuator cable to the cable bracket.
    10. Reconnect engine wire protector to No.4 timing belt cover
    11. Reinstall IAC valve pipe
    12. Reconnect engine wire protector to cowl top panel
    13. Reinstall ignition coils assemblies (See page IG-7 )
