Select larger rod end threads or stud rod end for greater strength. 2. BROKEN OR BENT ROD Cause: Misalignment or load in excess of cylinder capability. Solution: Make sure that rod is aligned properly through entire stroke. Consult your FABCO-AIR distributor to select proper rod size for application. 3.
