Subject: Pietenpol-List: Cylinder hold down bolts, or studsCylinder studs are subject to tension every time the jug fires. When one nut becomes loose the others have to make for this loss. That's why correct torque is imperative. If a person chooses to install a light material under a nut it will be a matter of time before the material is hammered out, causing the torque on that nut to be less. After this happens it is only a matter of time before the others are stretched out, and the cylinder can actually be blown off. I worked on a Bell 47 one time that this had happened too, although the cylinder never departed the case several studs had broken and a severe oil leek appeared. The result was a trashed case, and cylinder. ________________________________________________________________________________
