Drum pressure tension spring for the Hummel Includes the tension adjuster bolt and nuts When you change this you will have to set the machine back up the factory drum pressure. Setting bolt back to the same height will get it close but it may still be off. Too much pressure could overheat the motor. If you are getting reduced drum pressure or are getting waves you may want to change this. If you are getting waves also purchase the HS1110 bushings.
