Remove Pistons And Connecting Rods
START BY:a. remove cylinder head assembliesb. remove oil pump1. 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. 4. Push the pistons up until the piston rings are clear of the cylinder liner. Remove pistons (2). Keep each cap with its connecting rod.
Do not turn the crankshaft while any of the connecting rods are in the engine without the caps installed. Do not cause damage to the cooling tubes when the pistons are removed.
5. Do Steps 1 through 4 for the remainder of the pistons.Install Pistons And Connecting Rods
1. Put clean engine oil on the piston rings, connecting rod bearings and cylinder liners.2. Put two pistons in position opposite of each other in the correct bore of the block. Install pistons (1) with tool (A).
Make sure that the pistons are installed with flat surfaces (2) of the connecting rods toward each other and the chamfered sides (4) toward the crankshaft.
For more detail about the installation of connecting rod bearings see Remove And Install Connecting Rod Bearings.3. Check the bearing clearances with tool (B). See the topic Install Crankshaft for service tips on the use of Plastigage (A).4. Put 2P2506 Thread Lubricant on bolts (5). Install caps (3) and nuts finger tight. Tighten each nut to a torque of 80 8 N m (60 6 lb.ft.). Put a mark across the nuts and bolts. Tighten each nut 120° more.5. 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.6. Do Steps 1 through 5 for the remainder of the pistons.END BY:a. install oil pumpb. install cylinder head assembliesDisassemble And Assemble Pistons And Connecting Rods
START BY:a. remove pistons and connecting rods 1. Remove bearings (2) from the connecting rod and connecting rod cap.2. Remove retainer ring (1). Remove piston pin (3) from the piston and connecting rod. Separate the rod from the piston. 3. Use tool (A) to remove the piston rings (4) from the piston. 4. Heat the connecting rod to a temperature of 176° - 204°C (350° - 400°F). Put 5P8651 Spacer (12) in the base plate. Put connecting rod in position on the base plate of tooling (B).5. Put the connecting rod piston pin bearing end in the center of the port assembly of tooling (B). Install pin (8) in the center of the bore for the connecting rod bearings.6. Install 5P8653 Adapter (10). Put the hole in the adapter in alignment with the hole in the base plate of tooling (B).7. Install clamp bar (11) and clamp pin (7).8. Install new piston bearing (6) on adapter (10). The old bearing is pushed out by tooling (B) as the new bearing
