11-31. CHECK ALTERNATOR BELT TENSION. If properly installed, tensioned and checked periodically,
the alternator drive belt will give very satisfactory service. However, an improperly tensioned belt will wear
rapidly and may slip and reduce alternator output. Consequently, a belt should be checked for proper tension at
the time it is installed, again after 25 hours operation and at each 100 hour inspection thereafter.
The torque method for checking alternator belt tension is given as follows:
a. Apply a torque indicating wrench to the nut that attaches the pulley to the alternator and turn it in a
clockwise direction. Observe the torque shown on the wrench at the instant the pulley slips.
b. Check the torque indicated in step “a” with torque specified in the following chart. Adjust tension
accordingly.
