3. Remove nuts (1) and bearing caps (2). Push the rods and pistons up until the rings are out of the liners. 4. Remove two pistons (3) and rod assemblies from the cylinder liners. 5. Do Steps 1 through 4 for the rest of the pistons.Install Pistons
1. Put clean SAE 30 oil on the piston rings, connecting rod bearings and cylinder liners.2. Use tool (A) and a soft hammer to install pistons (1) in the cylinder liners. Be sure the numbers on the connecting rods are on the opposite side from the camshaft. 3. Install bearing caps (2) on the connecting rods. Make sure the numbers on the bearing caps are the same as the numbers on the connecting rods and that both numbers are on the same side of the connecting rod.4. Put SAE 30 oil on the threads of the rod bolts. Install the nuts and tighten to a torque of 60 6 lb.ft. (80 8 N m). Put a mark on nuts and cap. Tighten nuts an extra 120° 5° from the mark.end by:a) install oil pumpb) install cylinder head assemblyDisassemble And Assemble Pistons
start by:a) remove pistons 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. 3. Use tool (A) to remove the piston rings (4) from the piston. 4. Heat the connecting rod to a temperature of 350°-400°F (176-204°C). Put connecting rod (6) in position on the base plate of tooling (B). Put a new bearing (5) on the adapter of tooling (B). Put the adapter in position in the connecting rod and base plate of tooling (B). 5. Install the clamp bar (9) and clamp pin of tooling (B) in the connecting rod and base plate.6. Install the pusher adapter (7) and pusher (8) from tooling (B) on the adapter. The old bearing is pushed out by tooling (B) as the new bearing is installed.7. Use tooling (B) to push the new bearing into the connecting rod until the push adapter of tooling (B) makes full contact with the connecting rod surface. See USE OF PISTON PIN BEARING REMOVAL AND INSTALLATION TOOLS, SPECIAL INSTRUCTION, Form No. SMHS7295. Use tooling (C) for later type connecting rods (tapered ends).8. Check the piston pin bore diameter after the bearing is installed. The correct dimension is 2.0012 .0003 in. (50.830 0.008 mm).9. Clean the ring grooves in the piston before rings are installed. The two compression rings have marks "UP-1" and "UP-2". The rings must be installed with these marks toward the top of the piston with "UP-1" as the top ring. After installation of all three piston rings, put piston rings in position so gaps in rings are 120° apart. 10. Use tool (A) to install the piston rings on the piston. 11. Install bearings (2) in the connecting rod and connecting rod cap. Be sure the tabs in back of bearings are in the tab grooves of the connecting rod and connecting rod cap.12. Put piston (10) in position on the connecting rod. Put clean SAE 30 oil on piston pin (3) and install the piston pin. Install retainer rings (1). Make sure the retainer rings are in the grooves of the piston.end by:a) install pistons
