Just installed the new (to me) Ogura front pto. set the air gap at .018" per instruction sheet. torqued the v-belt pulley retaining bolt with cupped spring washer to 30-35 ft/lb. Before torquing this bolt I could barely rotate the pulley by hand. Not being able to rotate the pulley just about make impossible to get the belt on over the pulley. This does not seem to be normal?
