Install the retaining ring in the pin groove on one side of the piston.
Lubricate the pin and pin bores with clean engine oil.
NOTE: The piston must be installed onto the connecting rod with the correct orientation.
Hold the connecting rod so the camshaft side of the connecting rod faces outward. Refer to Procedure 001-999 in Section F. Install the piston onto the connecting rod so that the ‘Front’ mark and/or arrow are on the right side of the connecting rod. The notch at the bottom of the piston on the piston skirt will face inward.
Assemble the piston onto the connecting rod.
NOTE: Pistons do not require heating to install the pin, however, the pistons do need to be at room temperature or above.
Install the pin through the piston and connecting rod.
Install the second retaining ring.
The top surfaces of the upper and intermediate rings are identified either with the word “TOP” or a supplier
identification mark, such as a stamped dot. Assemble with the word “TOP” or the supplier mark facing upward.
The bottom , or oil control ring, can be installed with either side up.
The two-piece oil control ring must be installed with the expander ring gap 180-degrees from the gap of the oil
ring.
Use piston ring expander, Part Number 3823137, to install the rings on the piston .
The piston ring type and location can be identified by piston ring profile.
1 Top Piston Ring
2 Intermediate Piston Ring
3 Oil Control Ring .
Start by positioning the oil ring expander in the oil control ring groove. Then install the oil control ring, followed by
the intermediate ring, and finally the top ring .
