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 the respective connecting rod.
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
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).
Be 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 installation of connecting rod bearings see REMOVE AND INSTALL CONNECTING ROD BEARINGS.3. Check the bearing clearances with Plastigage. 4. Put clean engine oil on bolts (5). Install caps (3) and nuts finger tight. Tighten each nut to a torque of 60 6 lb.ft. (80 8 N m). Put a mark across the nuts and bolts. Tighten each nut 120° 5°.5. Check the side clearance between two connecting rods on the same crankshaft journal. Clearance must be .003 to .033 in. (0.076 to 0.838 mm) for new rods.6.

start by:a) remove pistons1. Remove the bearings from the connecting rod and connecting rod cap. 2. Remove retainer ring (1) with tool (C).3. Remove pin (2) and connecting rod (4) from piston (3). 4. Remove the piston rings from the piston with tool (A). Clean the piston ring grooves on the pistons with an acceptable ring groove cleaning tool.5. Heat the connecting rod in an oven to a temperature of 350°-500°F (176°-260°C). Never use a direct flame to heat a connecting rod. 6. Put spacer (12) in the base plate. Put connecting rod in position on the base plate of tooling (B).7. 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.8. Install adapter (10). Put the hole in the adapter in alignment with the hole in the base plate of tooling (B).9. Install clamp bar (11) and clamp pin (7).10. Install new piston bearing (6) on adapter (10). The old bearing is pushed out by tooling (B) as the new bearing is installed.
Make sure the oil hole in the bearing is in line with the hole in the rod.
9. Put adapter (9) in position as shown with the taper side down. The piston bearing joint must be in alignment with the hole in adapter (10) and the base plate of tooling (B).10. Put pusher (5) on adapter (9).11. Use tooling (B) to push the new piston pin bearing into the connecting rod until adapter (9) of tooling (B) makes full contact with the connecting rod surface.12. Remove the connecting rod and the old piston pin bearing from tooling (B).13. Check the piston pin bearing bore diameter after the bearing is installed. The correct dimension is 2.0012 .0003 in. (50.830 0.008 mm).14. Check the clearance between the ends of the piston rings. See PISTONS AND RINGS in SPECIFICATIONS.15. Install the oil ring spring in the oil ring grooves of the piston. The oil ring is to be installed over the spring with the oil ring end gap 180° from the oil ring spring joint. 16. Install the oil ring on the piston with tool (A).17. Install the second (intermediate) piston ring with the side that has the identification "UP-2" toward the top of the piston with tool (A).18. Install the first (top) piston ring with the side that has the identification "UP-1" toward the top of the piston with tool (A). After the installation of all three piston rings, put the piston ring in position so the end gaps are 120° apart. 19. Put piston (3) in position on connecting rod (4). Put clean engine oil on pin (2) and install the pin. Install retainer rings (1) with tool (C). Make sure the retainer rings are in the grooves of the piston.20. Install the bearings in the connecting rod and connecting rod cap.end by:a) install pistons
