  • Apparatus and method for installing connecting rods
    Patent number: 8484826
    Abstract: An apparatus and method for installing a piston and connecting rod assembly in a cylinder of an engine block includes a frame, an installation rod and a guide defining a channel complementary to the rod. The frame is disposed about an opening at the bottom of the engine block and the guide is positioned on the frame in alignment with a cylinder. The installation rod is coupled to the connecting rod and the rod and the piston and connecting rod assembly are slid into the cylinder. The installation rod is received within the guide channel and maintains the connecting rod perpendicular to the crankshaft and away from the cylinder wall. As the connecting rod moves toward the crankshaft, the guide and rod move the connecting rod into proper alignment and contact with the crankshaft.
