Remove Pistons & Connecting Rod Assemblies
Start By:a. remove cylinder head assemblyb. remove piston cooling tubes1. Remove the carbon ridge from the top inside surface of the cylinder liners. 2. Turn the crankshaft until two pistons are at bottom center.3. Remove bolts (1) and the bearing caps. Push the rods and pistons up until the rings are out of the cylinder liners.
If more than one piston is to be removed, the crankshaft can turn because of the weight of the remaining pistons. Lock the position of the crankshaft to prevent unexpected movement and personal injury or component damage.
4. Remove the pistons (marked x) and the connecting rods from the cylinder liners.5. Do Steps 1 through 4 for the remainder of the pistons and connecting rods.Install Pistons & Connecting Rod Assemblies
1. Put clean engine oil on piston rings, connecting rod bearings and cylinder liners. 2. Use Tool (A), and install piston (2) and the connecting rod in the cylinder liner. Be sure the number of the tab groove side of the connecting rod is on the opposite side from the camshaft.3. Install the bearing cap on the connecting rod with the number on the side of the bearing cap on the same side and same number as on the connecting rod.4. Put 2P-2506 Thread Lubricanton the threads of the bolts. Install the bolts, and tighten them to a torque of 90 8 N m (67 6 lb ft).Put a mark on the bolts and cap, and tighten the bolts an extra 90 5 degrees.5. Do Steps 1 through 4 for the remainder of the pistons and connecting rods.End By:a.

Start By:a. remove pistons and connecting rod 1. Remove bearings (3) from the connecting rod and connecting rod cap.2. Remove retainer ring (1) with Tool (A).3. Remove pin (2) and connecting rod (4) from the piston.
Piston rings (5) may break apart during removal from the pistons. If the rings are to be removed, wear eye protection to prevent possible personal injury from flying parts.
4. Remove piston rings (5) from the piston with Tool (B). Clean the piston ring grooves on the pistons with an acceptable ring groove cleaning tool. See Use Of Piston Pin Bearing Removal & Installation Tools, Special Instructions, SMHS7295.5. Heat connecting rod (4) in an oven to a temperature of 177° to 260°C (350° to 500°F).Never use a direct flame to heat a connecting rod. 6. Put connecting rod (4) in position on the base plate of Tooling (C). Put a new rod pin bearing (6) on the adapter part of Tooling (C). The old bearing is pushed out by Tooling (C) as the new bearing is installed.7. Use Tooling (C) to push the new bearing into the connecting rod until the push adapter of Tooling (C) makes full contact with the connecting rod surface.8. Use a pin boring machine to make the rod pin bearing the correct size. The bore
