PROCEDURE


  1. INSPECT V BELT


    1. A01SBEFC01
      *a CORRECT
      *b INCORRECT
      *c Clearance

      Visually check the belt for cracks, oiliness or wear. Check that the belt does not touch the bottom of the pulley groove.

      If necessary, replace the V belt.

    2. A01SD7CC01
      *1 Vane Pump Pulley
      *2 Crankshaft Pulley
      B0068HS Measuring Point for V belt Deflection

      Check the vane pump V belt deflection by pressing on the V belt at the point indicated in the illustration with 98 N (10 kgf, 22 lbf) of force.

      Standard Deflection
      Item Specified Condition
      New belt

      8 to 10 mm

      (0.315 to 0.393 in.)
      Used belt

      10 to 15 mm

      (0.394 to 0.590 in.)

      If necessary, adjust the vane pump V belt deflection.

    3. Reference:

      Using a belt tension gauge, check the vane pump V belt tension.

      Standard Tension
      Item Specified Condition
      New belt

      441 to 539 N

      (45.0 to 55.0 kgf, 99.1 to 121.2 lbf)
      Used belt

      245 to 343 N

      (25.0 to 34.9 kgf, 55.1 to 77.1 lbf)

      If the V belt tension is not as specified, adjust it.

      Note


      • Check the vane pump V belt tension at the specified point.

      • When installing a new V belt, set its deflection value as specified.

      • Perform the V belt tension and deflection value check after idling the engine for a few minutes.

      • When using a belt tension gauge, confirm the accuracy first by using a master gauge.

      • When reinstalling a V belt used for over 5 minutes, perform the check based on the used deflection value.

      • When checking a V belt used for over 5 minutes, confirm the deflection value is within the specified range.

    4. A01SCUOC01
      *1 Compressor Assembly with Magnet Clutch
      *2 Idle Pulley
      *3 Crankshaft Pulley
      B0068HS Measuring Point for V belt Deflection

      Check the cooler compressor V belt deflection by pressing on the V belt at the point indicated in the illustration with 98 N (10 kgf, 22 lbf) of force.

      Standard Drive Deflection
      Item Specified Condition
      New belt

      11 to 15 mm

      (0.434 to 0.590 in.)
      Used belt

      15 to 20 mm

      (0.591 to 0.787 in.)

      If necessary, adjust the cooler compressor V belt deflection.

    5. Reference:

      Using a belt tension gauge, check the cooler compressor V belt tension.

      Standard Tension
      Item Specified Condition
      New belt

      372 to 608 N

      (38.0 to 61.9 kgf, 83.7 to 136.6 lbf)
      Used belt

      196 to 392 N

      (20.0 to 39.9 kgf, 44.1 to 88.1 lbf)

      If the V belt tension is not as specified, adjust it.

      Note


      • Check the cooler compressor V belt tension at the specified point.

      • When installing a new V belt, set its deflection value as specified.

      • Perform the V belt tension and deflection value check after idling the engine for a few minutes.

      • When using a belt tension gauge, confirm the accuracy first by using a master gauge.

      • When reinstalling a V belt used for over 5 minutes, perform the check based on the used deflection value.

      • When checking a V belt used for over 5 minutes, confirm the deflection value is within the specified range.

    6. A01SC67C02
      *1 Water Pump Pulley
      *2 Generator
      *3 Crankshaft Pulley
      B0068HS Measuring Point for V belt Deflection

      Check the fan and generator V belt deflection by pressing on the belt at the point indicated in the illustration with 98 N (10 kgf, 22 lbf) of force.

      Standard Deflection
      Item Specified Condition
      New belt

      7.0 to 10 mm

      (0.276 to 0.393 in.)
      Used belt

      10 to 14 mm

      (0.393 to 0.551 in.)

      If necessary, adjust the fan and generator V belt deflection.

    7. Reference:

      Using a belt tension gauge, check the fan and generator V belt tension.

      Standard Tension
      Item Specified Condition
