Finally got around to replacing old belts. I can't get the daggum AC belt around the pulleys for the life of me. The tensioner pulley is bottomed out. Pull and tug as I may, I can't get the new one to fit. Prior to install, I lined the new belts (OEM from SOR) up with old and they appeared similar size, but I didn't measure. Any tips? Only thing I could think of it bump starting the motor to turn the crank, but am unsure which way it spins and don't want to mess up a new spendy belt. Lost a pair of safety glasses to frustration-induced spiking into the concrete driveway...
