The mechanism comprises a one-piece crosshead and a one-piece auxiliary drive member coupled together for mutual reciprocation, although with a space therebetween, by tensioning tie rods. The crosshead receives a crankshaft connecting rod, the crankshaft being rotatably journaled in a mechanism housing, and the connecting rod being coupled to the crosshead through oversize crosshead pins which oscillate with the translating connecting rod. Replaceable vertical and horizontal guide assemblies effect and maintain planar alignment between the crosshead and drive member. |
