Pistons & Connecting Rod Assemblies
Start By:a. remove cylinder headsb. remove oil pumpc. remove piston cooling tubes 1. Remove the carbon from the top inside surface of the cylinder liners.2. Turn the crankshaft until two pistons are at bottom center.3. Remove bearing caps (1) from the two connecting rods. Put pieces of rubber hose or tape on the threads of the connecting rod bolts as protection for the crankshaft. Put identification on each bearing cap so it will be installed on the correct connecting rod. 4. Push the pistons up until the piston rings are clear of the cylinder liner. Remove pistons (2).
Do not turn the crankshaft while any of the connecting rods are in the engine without the caps installed. Do not damage the cooling tubes when the pistons are removed.
5. Do Steps 1 through 4 for the remainder of the pistons.Install Pistons & Connecting Rod Assemblies
1. Be sure that the pistons are installed with flat surfaces (2) of the connecting rods caps toward each other and the chamfered sides (1) toward the crankshaft. 2. Put clean engine oil on the piston rings and cylinder liners.3. Put two pistons in position opposite of each other in the correct bore of the block. Install pistons (3) with Tool (A). For more detail about checking bearing clearances and installation of connecting rod bearings, see the topic, "Remove & Install Connecting Rod Bearings" in this Manual.4. Check the bearing clearances with Plastigage.5. Put clean engine oil on the bolts. Install the connecting rod caps and nuts finger tight. Make sure the flat side of each cap is toward the other cap. The chamfered side must be toward the crankshaft. Tighten each nut to a torque of 82 8 N m (60 6 lb ft). Put a mark across the nuts and bolts. Tighten each nut an additional 120 5 degrees (1/3 of a turn).
Do not use an impact wrench to tighten the nuts the additional 120 degrees (1/3 of a turn).
6. Check the side clearance between two connecting rods on the same crankshaft journal. Clearance must be 0.28 to 0.84 mm (.011 to .033 in) for new rods.7. Do Steps 1 through 6 for the remainder of the pistons.End By:a. install piston cooling tubesb. install oil pumpc. install cylinder headsDisassemble & Assemble Piston & Connecting Rod Assemblies
