ENGINE UNIT INSPECTION


  1. INSPECT IDLE GEAR NO. 1 OIL CLEARANCE


    1. A01KH1J

      Using a cylinder gauge, measure the inside diameter of the idle gear.

      Idle gear inside diameter
      44.000 - 44.025 mm (1.7323 - 1.7333 in.)
    2. A01KEFD

      Using a micrometer, measure the diameter of the idle gear shaft.

      Idler gear shaft diameter
      43.955 - 43.990 mm (1.7305 - 1.7319 in.)

    3. Subtract the idle gear shaft diameter measurement from the idle gear inside diameter measurement.

      Standard oil clearance
      0.010 - 0.070 mm (0.0004 - 0.0028 in.)
      Maximum oil clearance
      0.20 mm (0.0079 in.)

      If the clearance is greater than maximum, replace the gear and shaft.

  2. INSPECT CYLINDER HEAD SET BOLT


    1. A01KINLE01
      Text in Illustration
      *a Measuring Point
      *b Elongated Thread

      Using vernier calipers, measure the minimum outer diameter of the compressed thread at the measuring point.

      Standard outer diameter
      11.8 - 12.0 mm (0.465 - 0.472 in.)
      Minimum outer diameter
      11.6 mm (0.457 in.)

      If the outer diameter is less than minimum, replace the bolt.

  3. INSPECT INJECTION GEAR BEARING


    1. Check that bearing is not rough or worn.

      If necessary, replace the bearing.
