62. Piston, Connecting Rod, and Bearing Installation

- Tools Required
- J 5239 Connecting Rod Bolt Guide Set
- J 8037 Ring Compressor
- J 36660 Electronic Torque Angle Meter

1. Apply clean engine oil to the following components:
- The piston
- The piston rings
- The cylinder bore
- The connecting rod bearing surfaces





2. Install the J 5239 onto the connecting rod bolts.





3. Install the J 8037 onto the piston and compress the piston rings.

Important: The mark on the top of the piston must face the front of the engine block.
When assembled, the flanges on the connecting rod and connecting rod cap should point to the front of the engine block on the left bank and point to the rear of the engine block on the right bank.





4. Install the piston and connecting rod assembly, and the J 8037 into the proper cylinder bore.





5. Use the J 8037 and the J 5239 and lightly tap the top of the piston with a wooden hammer handle.
5.1. Hold the J 8037 firmly against the engine block until all of the piston rings have entered the cylinder bore.
5.2. Use the J 5239 in order to guide the connecting rod onto the crankshaft journal.





6. Remove the J 5239 from the connecting rod bolts.

Notice: Refer to Fastener Notice in Service Precautions.





7. Install the connecting rod cap and nuts.
7.1. Tighten the nuts on the first pass evenly to 27 Nm (20 ft. lbs.).
7.2. Tighten the nuts on the final pass to 55 degrees using the J 36660.





8. Once the piston and connecting rod assemblies have been installed, lightly tap each connecting rod assembly (parallel to the crankpin) in order to make sure that the connecting rods have the proper side clearance.
9. Use a feeler gauge or a dial indicator to measure the side clearance between the connecting rod caps. The connecting rod side clearance measurement should be 0.15 - 0.68 mm (0.006 - 0.027 inch).
