3. Remove connecting rod caps (1) from the two connecting rods and push the pistons up until the rings are free of the cylinder liner.4. Remove the two pistons.5. Do the above steps again for the remainder of the pistons.Install Pistons
1. Turn the crankshaft until the bearing journals for the pistons to be installed are at bottom center.2. Put clean engine oil on the crankshaft journals and on the inside of the cylinder liners. Put clean engine oil on the piston rings and connecting rod bearings.3. Move the piston rings on the piston until the ring openings (gap) are approximately 180° apart.
Never install tool (A) (the ring compressor) without the use of the cylinder liner as a guide. Damage to the piston rings can be the result.
TYPICAL EXAMPLE4. Put tool (A) in position on the cylinder liner as shown. Put the connecting rod and piston in position in the same cylinder liner from which it was removed and into the ring compressor. Make sure the "V" mark on the piston is in alignment with the "V" mark on the cylinder block.5. Push the piston into position while the connecting rod is put into position over the crankshaft. 6. Put clean engine oil on bearings, bolt threads and surfaces of the nuts that make contact with the connecting rod caps. Put caps (1) in position on the connecting rods and install the nuts. Tighten the nuts to a torque of 30 3 lb.ft. (40 4 N m). Put a mark on each nut and the end of each bolt. Tighten the nuts 90° more.
When the connecting rod caps are installed, make sure the number on the side of the cap is next to and respective with the number on the side of the connecting rod.
7. Follow Steps 1 through 6 for the installation of the other pistons.end by:a) install oil pumpb) install cylinder head assemblyDisassemble And Assemble Pistons
start by:a) remove pistons 1. Remove keystone rings from the piston with tool (A). 2. Remove snap ring (3), piston pin (1) and connecting rod (2) from the piston.3. Clean the piston ring grooves on the old piston with an acceptable ring groove tool. For clearances on pistons and rings of earlier models, see PISTON AND RINGS in SPECIFICATIONS.4. See SPECIAL INSTRUCTIONS, Form SMHS7295 for USE OF PISTON PIN REMOVAL AND INSTALLATION TOOLS. Be sure to remove the bearings from the crankshaft end of connecting rod.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 the connecting rod in position on tooling (B) for the regular rod. Use tooling (C) for the tapered rod. Put a new rod pin bearing in position. Make sure the rod pin bearing joint (4) is 90° from a center line through crankshaft and pin bearing bores.7. Remove the old rod pin bearing and install the new rod pin bearing with one operation. 8. Use a pin bearing machine to make the bearing the correct size. The bore in the bearing (new) must be 1.5017 .0003 in. (38.143 .008 mm). The maximum permissible clearance between the bearing and piston pin (worn) must not be more than .003 in. (0.08 mm).9. Put the connecting rod in position in the piston with bearing tab groove (5) and number identification on the same side as the "V" mark on the top of the piston. 10. Install piston pin (1) and retaining ring (3).11. Check the clearance between the ends of the piston rings (end gap) with the rings installed in a cylinder liner with a bore size of 4.750 in. (120.65 mm). The clearance of the top ring and middle ring is .0245 .0075 in. (0.622 0.191 mm). The clearance for the 9S7788 Oil Ring is .0205 .0075 in. (0.521 0.191 mm). The clearance for 9L6934 Oil Ring is .0225 .0075 in. (0.572 0.191 mm).12. Install the oil ring spring in the oil ring groove of the piston. The oil ring (7) must be installed on the piston with the ring end gap 180° from the oil ring spring joint. 13. Install the oil ring (7) on the piston with tool (A).14. Install the top piston ring (6) with the side that has the mark "UP" toward the top of the piston with tool (A).15. Check the clearance between the piston oil ring groove and the oil ring. The maximum permissible clearance for this ring and piston groove must not be more than .006 in. (0.15 mm). Make sure piston ring end gaps are 90° apart before the pistons are installed.
