START BY:a. remove timing gear coverb. remove flywheel housingc. remove pistons and connecting rods 1. Turn the crankshaft until the "C" mark on the crankshaft drive gear is in alignment with the "C" mark on the camshaft drive gear as shown. The main bearing caps are installed with the part number toward the front of the engine. Each cap has a number on the front of the cap which is the same as the number on the camshaft side of the cylinder block.2. Remove the three center main bearing caps (1). 3. Remove thrust bearings (2) from each side of the center crankshaft journal. 4. Remove bolt (3). Remove the oil pickup tube support strip and the clip from the cylinder block as a unit.5. Install one of the flywheel bolts in the end of the crankshaft.6. Fasten a nylon strap and a hoist on crankshaft (4) as shown.7. Remove the two end caps.
Be careful not to damage the crankshaft journals when the crankshaft is removed.
8. Remove crankshaft (4) from the cylinder block. The weight of the crankshaft is 52 kg (115 lb.).
If new main bearings are not to be installed during crankshaft installation, put identification marks on the original bearings as to their location in the engine.
9. Remove the crankshaft main bearings from the cylinder block and from the main bearing cap.10. Check the condition of the main bearings and crankshaft. Make reference to Guideline For Reusable Parts: Main And Connecting Rod Bearings, Form No. SEBF8009 and Visual Inspection Of Crankshafts, Form No. SEBF8043. 11. Use tooling (A), and remove the drive gear from the crankshaft.Install Crankshaft And Gear
1. Heat the crankshaft drive gear to a maximum temperature of 315° (600°F). Install drive gear (1) on the crankshaft with the "C" mark on the gear toward the pulley end of the crankshaft. 2. Clean the surfaces in the cylinder block for the main bearings. Install the upper main bearing halves (bearings with the oil hole) in the cylinder block. Install the main bearings dry when the clearance checks are made. Put clean oil on the main bearings for final assembly.3. Fasten a nylon strap and a hoist on crankshaft (2), and put it in position in the cylinder block with the "C" marks on the camshaft drive gear and crankshaft drive gear in alignment. 4. Install a thrust plate (4) on each side of the No. 3 main bearing saddle. Put the side of the thrust plate which has the identification mark "BLOCK SIDE" toward the bearing saddle and the side with the oil grooves toward the crankshaft.5. Put the clip and oil pickup tube support strip in position on the cylinder block as a unit, and install bolt (3) that holds them in place.6. Clean the surfaces of the main bearing caps for the main bearings. Install the lower main bearing halves in the main bearing caps. Be sure the tabs on the back side of the main bearings fit in the grooves of the main
