A compressor may include a shell, a crankshaft, a piston and a connecting rod. The shell may define a cylinder. The crankshaft is supported for rotation relative to the shell. The piston reciprocates within the cylinder in response to rotation of the crankshaft. The piston and the cylinder define a compression chamber therebetween. The connecting rod includes a first bushing rotatably coupled to the piston and a second bushing rotatably coupled to the crankshaft. The second bushing may include a driving surface contacting the crankshaft and having a recess formed therein. The recess receives an insert.
