Tools Required

Important: The piston and cylinder bore have been measured and the bore has been sized for the proper clearance. Install the piston and connecting rod assembly into the proper cylinder bore. The piston alignment mark MUST face the front of the engine block.

1. Lightly lubricate the following components with clean engine oil:

•	The piston

•	The piston rings

•	The cylinder bore

•	The bearing surfaces

2. Stagger the oil control ring end gaps a minimum of 90 degrees.
3. Stagger the compression ring end gaps a minimum of 25 mm (1.0 in).
4. Install the J 8037 onto the piston and compress the piston rings.
5. Install the J 41556 into the connecting rod.




Important: The piston alignment mark MUST be facing the front of the engine block.

6. Install the piston and connecting rod assembly into the proper cylinder bore.

Notice: When installing the pistons into the cylinder bore, make sure not to contact the piston oil nozzle with the connecting rod. Failure to do so may damage the piston oil nozzle, resulting in potential engine damage.

7. Hold the piston ring compressor firmly against the engine block. Using a wooden hammer handle, lightly tap the top of the piston until all of the piston rings enter the cylinder bore.



8. Using J 41556 , guide the connecting rod end onto the crankshaft journal.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

9. Install the bearing, bearing cap and bolts.

Tighten

1. Tighten the connecting rod bearing cap bolts a first pass to 25 N·m (18 lb ft).
2. Tighten the connecting rod bearing cap bolts a final pass to 110 degrees using the J 45059 .



10. With the pistons and connecting rods installed, use a soft faced mallet and lightly tap each connecting rod assembly parallel to the crankpin to make sure that the rods have side clearance.
11. Measure the connecting rod side clearance using a feeler gage or dial indicator. Connecting rod side clearance should be within 0.18-0.44 mm (0.007-0.017 in).
