Piston, Connecting Rod, and Bearing Installation

^ Tools Required
- J 41742 Connecting Rod Guide
- J 43953 Piston Ring Compressor





1. Install the J41742 onto the connecting rod hole which will allow the guide pin to clear the crankshaft bearing bridge. Only 1 J 41742 is required to properly align the connecting rod with the crankshaft.
2. Install the upper rod bearing to the rod.
3. Coat the following components with clean engine oil:
^ The piston
^ The piston rings
^ The cylinder bore
^ The bearing surfaces





4. Perform the following steps to install the piston:

Important: The bump on the connecting rod and the cap must face the rear of the block.

4.1. Position the piston with the arrow on the piston head facing toward the front of the engine.
4.2. Use the J 43953 to compress the piston rings.
4.3. Place the piston in the cylinder.
4.4. Lightly tap the piston into the cylinder bore while an assistant guides the connecting rod onto the crankshaft.
5. Remove the J 41742.





6. Perform the following steps to install the connecting rod caps with the bearings to the connecting rod:
6.1. Install with the bumps on the connecting rod and the cap facing toward the rear of the engine.
6.2. Coat the bearing surface with clean engine oil.

Notice: Refer to Fastener Notice in Service precautions.

Important: Use new connecting rod cap bolts.

7. Install the connecting rod cap bolts. Tighten
7.1. First Pass: Tighten the connecting rod cap bolts to 35 Nm (26 ft. lbs.).
7.2. Second Pass: Plus 45 degrees
7.3. Final Pass: Plus 15 degrees
8. Repeat the steps for the remaining pistons.
