(1) The 9S-9082 Engine Turning Tool is alternative tooling.Start By:
Remove the cylinder head.
Remove the piston cooling jets.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g00913801
Use Tooling (A) to rotate the crankshaft until bolts (1) can be removed.
Remove the carbon ridge from the top inside surface of the cylinder liner.
Inspect the connecting rod and connecting rod cap for the proper identification mark. The connecting rod and the connecting rod cap should have an etched number on the side. The number should match the cylinder number. Mark the connecting rod and the connecting rod cap, if necessary. Note: Do not stamp the connecting rod assembly.
Remove bolts (1) and connecting rod cap (2). Push the connecting rod until the piston rings are out of the cylinder liner.
Remove the piston and the connecting rod from the cylinder liner. Note: Be careful not to damage the cylinder liner or the crankshaft journal during the removal of the piston and the connecting rod.

Use Tooling (B) to remove the retaining rings that hold piston pin (4). Remove piston pin (4). Remove piston (3) from connecting rod (5).
Remove the bearings from connecting rod (5) and the connecting rod cap. Note: If necessary, separate the piston skirt from the piston crown.

(1) The 9S-9082 Engine Turning Tool is alternative tooling.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Install the connecting rod bearings dry when clearance checks are performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check". Apply clean engine oil on the connecting rod bearings for final assembly.

Use Tooling (C) to install the piston rings onto the piston.
For the oil control ring, ensure that the ends of the spring are 180 degrees from the ring gap. The white portion of the spring must be visible at the ring gap.
Install the intermediate ring with the side marked "UP-2" toward the top of the piston.
Install the top ring with the side marked "UP-1" toward the top of the piston.
After the rings are installed, rotate the rings so that the gaps are spread apart by 120 degrees. Orient the oil control ring gap toward the bore for the piston pin.
Illustration 5 g01006026
Place the piston crown into the piston skirt. Use clean engine oil to coat the bore of piston (3), piston pin (4), and the piston pin bearing in connecting rod (5). Position connecting rod (5) inside piston (3). Insert piston pin (4) through piston (3) and the bearing.
