Piston & Rod Assembly
- Each rod is sorted into one of 4 tolerance ranges between 0.0 and 0.009" (0.0 and 0.024 mm) in 0.0002" (0.006 mm) increments. Depending on big end bore size, a number between 1 and 4 is stamped on side of connecting rod big end. Any combination of numbers may be found in any engine and numbers do not refer to cylinder position. Stamped number is positioned so that half is on the connecting rod and half is on the bearing cap.
- Install connecting rod to piston so mark on shank of connecting rod is on the same side as arrow on top of piston. Install piston and connecting rod so arrow on top of piston and mark on connecting rod point toward timing belt. See Figure.
