Checking Adjustment
| CAUTION | The drive belt deflection can be inspected only between specified pulleys. Perform the drive belt deflection/tension inspection when the engine is cold, or at least 30 minutes after the engine has stopped. If the drive belt that is being used exceeds the deflection/tension limit, adjust it to the used deflection/tension specification. Adjust belt to new deflection/tension specifications if a belt has been on a running engine for less than 5 minutes. |
Note. Belt Tension Gauge (49 9200 020A), or equivalent is required to check belt tension. see scheme 7
Note. The drive belt tension can be inspected anywhere between the pulleys. The drive belt deflection can be inspected only between specified pulleys. If the drive belt deflection is at the deflection limit or more, or the drive belt tension is at the tension limit or less, adjust the drive belt tension.
Apply moderate pressure of 22 ft. lbs. (98 N) midway between the specified pulleys and inspect the deflection. (Scheme 1) Otherwise, inspect the tension using the Belt Tension Gauge (49 9200 020A), or equivalent. (Scheme 2) See BELT DEFLECTION SPECIFICATIONS or BELT TENSION SPECIFICATION table. If the deflection/tension is not within the specification, adjust it.
