DRIVE BELT DEFLECTION/TENSION INSPECTION [13B-MSP]


id011070804400

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 min after the engine has stopped.
•  If the drive belt that is being used exceeds the deflection/tension limit, adjust it to the deflection/tension used when adjusting.

1.  Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [13B-MSP].)

2.  Apply a pressure of 98 N {10 kgf, 22 lbf} to the back of the drive belt in the middle of the pulleys shown in the figure and inspect the deflection. Otherwise, inspect the tension using the SST.

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 deflection/tension.
