<p>The rod cap fracturing machine (10) is for cracking a rod cap (68) along a rod cap cracking plane (P) that is intersected by connecting rod center line (110) at an acute angle. The machine includes a first mandrel portion (58) fixed to a frame (12) and a second mandrel portion (60) on a carriage (40). A rod cap clamp assembly (74) on the carriage clamps the rod cap to the second mandrel portion. First and second wrist pin clamps (116, 118) clamp the wrist pin end (106) of the rod body along a line (124) perpendicular to the rod center line and prevent pivotal movement of the rod body relative to the crankshaft bore axis (114). A crankshaft end clamp (128) clamps the rod body to the first mandrel half and prevents bending of the long arm (134) of the rod.</p> |
