Drive Belt: Testing and Inspection

DRIVE BELT INSPECTION
Drive Belt Deflection Check





Deflection





GENERATOR, P/S, P/S +A/C





A/C

1. Verify the drive belt deflection when the engine is cold, or at least 30 minutes after the engine has stopped. Apply moderate pressure 98 N (10 kgf, 22 lbs.) midway between the specified pulleys. If the deflection is not within the specification, adjust it.

Drive Belt Tension Check
1. Belt tension can be verified in place of belt deflection.
2. Verify the drive belt tension when the engine is cold, or at least 30 minutes after the engine has stopped.
3. Using the SST verify the belt tension between any two pulleys.
^ If the tension is not within the specification, adjust it. Adjustments








Tension
A belt that has been on a running engine for less than 5 minutes
