Connecting Rod for Diesel Engines: Weichai, Baudouin and Yuchai
A connecting rod transfers the firing impulse from the piston to the crankshaft, and its big end carries the highest alternating load of any bearing in a diesel engine. Because the rod is a matched assembly rather than a single part, buying the right one depends on the rod number, the piston pin diameter and the weight class of the set. Connecting rod part numbers by engine The table below lists the rod assemblies we hold for the Weichai, Baudouin and Yuchai families. Use the engine plate and the old rod number together — two rods can share a length and big end diameter and still differ in weight class.

Small end bush diameter — must match the piston pin; a worn bush loads...
