Information:

2. Put identification marks on counterweights (1), and remove them from the crankshaft 3. Remove bearing caps (2) from the connecting rod, and push the connecting rods away from the crankshaft Use wire to hold the upper half of the connecting rods away from the crankshaft 4. Remove the center main bearing cap, and remove two thrust plates (3) from each side of the main bearing.
Typical Example5. Use two of the bolts that hold the flywheel to the crankshaft, and install a bolt in each end of the crankshaft Fasten a hoist to the crankshaft as shown.6. Remove the remainder of main bearing caps (5), and remove crankshaft (4) from the cylinder block. The weight of the crankshaft is approximately 800 kg (1760.0 lb). 7. Remove the upper halves of the bearings from the cylinder block and the connecting rod assemblies.8. If necessary, remove bolts (7) to remove gears (6) from each end of the crankshaftInstall Crankshaft
1. If gears (6) were removed from the crankshaft, install the gears on each end of crankshaft (4). The upper halves of the main bearings have an oil hole in the center of the bearing.2. Install the upper halves of main bearings (8) in the block.3. Put the upper halves of rod bearings (9) in position in the connecting rod assemblies. Install the bearings dry when clearance check are made. Put clean engine oil on the bearings for final assembly.If the crankshaft journals and bores for the block and rods were measured at disassembly and found to be within specifications, no further checks are necessary. However, if the serviceman still wants to measure the bearing clearances, Plastigage is recommended. Lead wire, shim stock or use of a dial bore gauge can damage the bearing surface.The serviceman must be very careful to use Plastigage, tool (B) correctly. The following points must be remembered:...Make sure that the backs of the bearings and the bores are clean and dry....Make sure that the bearing locking tabs are properly seated in their slots....The crankshaft must be free of oil where the Plastigage touches it....If the main bearing clearances are checked with the engine upright or on its side, the crankshaft must be supported. Use a jack under an adjacent crankshaft counterweight and hold the crankshaft against the crown of the bearing. If the crankshaft is not supported, the weight of the crankshaft will cause incorrect readings....Put a piece of Plastigage on the crown of the bearing half that is in the cap. Do not allow the Plastigage to extend over the edge of the bearing....Install the bearing cap using the correct torque-turn specifications. Do not use an impact wrench. Be careful not to dislodge the bearing when the cap is installed....Do not turn the crankshaft with the Plastigage installed....Carefully remove the cap but do not remove the Plastigage. Measure the width of the Plastigage while it is in the bearing cap or on the crankshaft journal. Do this by using the correct scale on the package. Record
