CLUTCH UNIT (for 1GR-FE) INSPECTION


  1. INSPECT CLUTCH DISC ASSEMBLY

    Note

    When replacing the clutch disc assembly, make sure to perform an inspection of the flywheel sub-assembly and clutch cover assembly.


    1. A015AXF

      Using a vernier caliper, measure the rivet depth.

      Minimum Rivet Depth
      0.3 mm (0.0118 in.)

      If the depth is less than the minimum, replace the clutch disc assembly.

    2. A0155LV

      Using a dial indicator with a roller instrument, check the clutch disc runout.

      Maximum Runout
      0.9 mm (0.0354 in.)

      If the runout is more than the maximum, replace the clutch disc assembly.

  2. INSPECT CLUTCH COVER ASSEMBLY

    A015BQ3E01

    1. Using a vernier caliper, inspect the depth and width of wear of the diaphragm spring.

      Maximum Wear
      Depth Width
      0.6 mm (0.0236 in.) 5.0 mm (0.197 in.)

      If the wear is more than the maximum, replace the clutch cover assembly.

    2. A0156GPE01

      *1 Hair cracks, scratches or discoloration
      *2 Hair cracks, discoloration or excessive wear

      Perform a visual inspection of the clutch cover assembly.


      1. Inspect for hair cracks or scratches extending from the center outwards, or discoloration.

      2. Inspect for hair cracks in a circular pattern, discoloration or excessive wear.

        If there is any damage, replace the clutch cover assembly.

  3. INSPECT FLYWHEEL SUB-ASSEMBLY

    A0159D2

    1. Using a dial indicator, inspect the flywheel runout.

      Maximum Runout
      0.1 mm (0.00393 in.)

      If the runout is more than the maximum, replace the flywheel sub-assembly.

    2. A015ABLE01
      Text in Illustration
      *1 Hair cracks, scratches or discoloration
      *2 Hair cracks, discoloration or excessive wear

      Perform a visual inspection of the flywheel sub-assembly.


      1. Inspect for hair cracks or scratches extending from the center outwards, or discoloration.

      2. Inspect for hair cracks in a circular pattern, discoloration or excessive wear.

        If there is any damage, replace the flywheel sub-assembly.

  4. INSPECT CLUTCH RELEASE BEARING ASSEMBLY

    A01574ME01

    1. Check that the clutch release bearing moves smoothly without abnormal resistance by turning the sliding parts of the clutch release bearing (contact surfaces with the clutch cover) while applying force in the axial direction.

    2. Inspect the clutch release bearing for damage or wear.

      Replace the release bearing assembly as necessary.

  5. INSPECT INPUT SHAFT BEARING

    A0157GJE04

    1. Turn the bearing by hand while applying force in the direction of the rotation.

      If the bearing is stuck or difficult to turn, replace the input shaft bearing.

      Tech Tips

      The bearing is permanently lubricated and requires no cleaning or lubrication.

  6. REPLACE INPUT SHAFT BEARING

    A015696E01

    1. Using SST, remove the bearing.

      SST
      09303-35011
    2. A015CHIE01

      Using SST and a hammer, install a new bearing.

      SST
      09304-12012

      Tech Tips

      After installing the input shaft bearing to the engine side, make sure that it rotates smoothly.
