Typical example |
The pistons and connecting rods are matched to each cylinder. Note the position of each connecting rod and piston for correct assembly.
Identification marks (1) on the connecting rod and on the connecting rod cap must be matched and aligned. When the connecting rod is installed correctly, the marks should face the right side of the engine.
Refer to Systems Operation, Testing and Adjusting, "Connecting Rod - Inspect" for the procedure to measure distortion and parallelism of the connecting rod.
