If belt deflection is out of specification, adjust by removing or adding shims between the driven clutch sheaves Remove shims to decrease belt deflection Add shims to increase belt deflection See Driven Clutch DisassemblyInspection, pages 6.16 6.17NOTE: At least one shim must remain between the inner and outer sheave of the driven clutchIf proper belt deflection cannot be obtained, measure drive belt width, length, and center distance of drive and driven clutch, outlined in this section; all have an effect on belt deflection
