Abstract
Engine accessory drive belt tension is maintained by a spring loaded roller positioned to impinge against the belt. Belt deflection is reflected by changes in position of the roller, and measured by a deflection sensor. Changes in deflection may indicate changes in belt elasticity, indicating the possible need to change the belt.
