5. TENSIONING THE BELT (continued…)


If not using a belt tension gauge, a good rule of thumb is to apply 20lbs. of force

in between the idler and alternator pulley. In doing so, the measured horizontal
deflection of the belt should be approximately ¼”.


After belt tension is set appropriately, you may now torque down the button head

socket cap screws. Torque both bolts to no more than 15 ft-lbs (180 in-lbs).


Once the tensioner block has been locked into place, the adjustment bolt will

now be relieved of its tension. Because of this, you will want to tighten the
adjustment bolt ¼ turn (90 deg) more in order to secure it in place.
