A/C compressor drive belt(4JJ3) installation

1. A/C compressor drive belt installation

1. M/T models (Euro 5 or above)

1) Install the A/C compressor drive belt to the following parts.

  • Tension pulley
  • A/C compressor
  • Crankshaft pulley
  • Idle pulley

2. A/C compressor drive belt adjustment

1. M/T models (Euro 5 or above)

When installing a new belt, initial stretching of the belt occurs.
In addition, when reusing the belt, the belt needs to be fitted to the pulley groove.
After fitting the A/C compressor drive belt, adjust the tension of the A/C compressor drive belt again.

1) Loosen the tension pulley lock nut.

2) Turn the tension pulley adjust bolt to adjust the tension.

Note

  • The standard deflection shown is the value obtained when the specified load is applied to the measurement point of the A/C compressor drive belt.

98 N { 10.0 kg / 22 lb } Load

Caution

  • Accurately adjust the tension as there is a possibility the service life of the belt may be shortened or belt squeal may be generated if the tension is not within the appropriate range.
  • Use a sonic tension meter to verify accurate tension adjustment.
