Turning the piston and connecting rod assembly will prevent the connecting rod from hitting and damaging the piston cooling jet. When the connecting rod has passed the piston cooling jet, turn the connecting rod until the arrow or "Front" mark on the top of the piston is toward the front of the engine.The piston height is controlled by the length of the connecting rod. Connecting rods are supplied in six grades of length. The different grades of length are manufactured by machining the hole in the piston pin bearing in an off-center position. The different grades of length are created by the following method:
Machining the center of the hole in the piston pin
Machining the center of the hole in the bearing
If the connecting rod is replaced, ensure that the same grade of length as the original connecting rod is used.However, if the crankshaft or the cylinder block is replaced, the required grade of length of the connecting rods may change.A correct grade of length of a connecting rod can be ordered for replacement. The connecting rod includes the piston pin bearing. The piston pin bearing is machined in order to create the correct grade of length. The piston pin is installed in the connecting rod at the factory. Table 1 provides the specifications for the grade of length.Note: The length of the connecting rod is determined by the following method: The bearing for the crankshaft journal must be removed and the piston pin must be installed. The original grade of length of the connecting rod is determined when the original piston pin is installed.
