2. Turn the crankshaft until two pistons are at bottom center.3. Remove nuts (1) and the bearing caps. Push the rods and pistons up until the rings are out of the cylinder liners. 4. Remove pistons (2) and connecting rods from the cylinder liners.5. Do Steps 1 through 4 for the remainder of the pistons and connecting rods.Install Pistons And Connecting Rod Assemblies
1. Put clean engine oil on piston rings, connecting rod bearings and cylinder liners. Some engines use pistons which have the word "FRONT" stamped on the crown of the piston. These pistons also have a green color code on the bottom surface of the side relief directly under the word "FRONT". Make sure the word "FRONT" and the color code are toward the front of the engine when the piston is installed.2. Use tool (A), and install piston (1) and the connecting rod in the cylinder liner. Be sure the number on the tab groove side of the connecting rod is on the opposite side from the camshaft. Also, be sure the word "FRONT" on the crown of the piston is toward the front of the engine. 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 2P2506 Thread Lubricant on the threads of the bolts. Install the nuts, and tighten them to a torque of 80 8 N m (60 6 lb.ft.). Put a mark on the nuts and cap, and tighten the nuts an extra 120°.5. Do Steps 1 through 4 for the remainder of the pistons.END BY:a. install oil pumpb. install cylinder head assemblyDisassemble And Assemble Pistons And Connecting Rod Assemblies
START BY:a. remove pistons and connecting rod assemblies 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. 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 And Installation Tools, Special Instructions, Form No. 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 in the new rod pin bearing must be 50.830 0.008 mm (2.0012 .0003 in.).9. Check the
