Belt width narrows as wear then pulleys cant maintain speed. A hyd valve block below starter has a screw to release pressure to open engine pulleys, bolt by spring on fan side to open fan pulleys. Just did engine side on mine and belt. Updated drives on for 9 liter tractors dont have spring on fan side not sure on combines.
