Special Tools

EN-45059 Torque Angle Sensor Kit


    Object Number: 2026849  Size: SH
  1. Install the inner plunger and calibrate with the micrometer gauge (1).
  2. Mount the connecting rod bearing cover on the connecting rod.
  3. Caution: Refer to Fastener Caution in the Preface section.

  4. Tighten the 2 bolts in three passes using the EN-45059 sensor kit :
  5. 3.1. First pass tighten to  35 N·m (26 lb ft).
    3.2. Second pass tighten to an additonal  45° degrees.
    3.3. Third pass tighten to an additional  15° degrees.

    Object Number: 2026850  Size: SH
  6. Measure the connecting rod bearing diameters at 3 points.
  7. Measure at points A, B and C with the internal measuring device.


    Object Number: 2026852  Size: SH
  8. Work out the average connecting rod diameter.
  9. Formula: A+ B+ C /3.

  10. Measure the connecting rod bearing journal diameter at 2 points.
  11. Measure at points A and B with the micrometer gauge.


    Object Number: 1935590  Size: SH
  12. Work out the average connecting rod bearing journal diameter.
  13. Formula: A + B/2.

  14. Determine the connecting rod bearing play.
  15. Calculation formula: average connecting rod bearing diameter - average connecting rod bearing journal diameter.

  16. Perform the target/actual comparison.
  17. Permissible connecting rod bearing play: 0.019-0.071 mm (0.007-0.0028 in).

  1. Remove the oil pan. Refer to Oil Pan Removal.

  2. Object Number: 2026855  Size: SH
  3. Remove the connecting rod bearing cap.

  4. Object Number: 2026853  Size: SH
    2.1. Mark the installation position (1) of the connecting rod bearing cap.
    2.2. Remove the 2 bolts.
    2.3. Degrease the connecting rod bearing cap and wet the connecting rod bearing clip with engine oil.

    Note: Do not rotate the crankshaft.

  5. Lay on plastigage. Refer to Adhesives, Fluids, Lubricants, and Sealers for the recommended plastigage.
  6. Lay plastigage (flexible plastic thread) over the entire width of the connecting rod bearing journal.

  7. Install the connecting rod bearing cap.
  8. Caution: Refer to Fastener Caution in the Preface section.

  9. Tighten the 2 bolts in three passes using the EN-45059 sensor kit :
  10. 5.1. First pass tighten to  35 N·m (26 lb ft).
    5.2. Second pass tighten to an additional  45° degrees.
    5.3. Third pass tighten to an additional  15° degrees.

    Object Number: 2026855  Size: SH
  11. Remove the connecting rod bearing cap.
  12. Remove the 2 bolts.


    Object Number: 2026856  Size: SH

    Note: When reading the value, do not confuse millimeters and inches on the measuring scale.

  13. Measure the connecting rod bearing play.
  14. • Compare the width of the flattened plastic thread with the measuring scale.
    • Permissible connecting rod bearing play: 0.019-0.071 mm (0.0007-0.0028 in).

    Note: Check markings on parts.

  15. Install the connecting rod bearing cap.
  16. • Wet the connecting rod bearing journal and con-rod bearing clips with engine oil.
    • Renew the bolts.
  17. Tighten the 2 bolts in three passes using the EN-45059 sensor kit :
  18. 9.1. First pass tighten to  35 N·m (26 lb ft).
    9.2. Second pass tighten to an additional  45° degrees.
    9.3. Third pass tighten to an additional  15° degrees.
  19. Install the oil pan. Refer to Oil Pan Installation.
