The crankshaft can be removed after taking out the engine from the car and removing the engine oil pump. The oil pan gasket must not be pried because it is secured to the cylinder block at three points and will not unscrew when the pan is removed. Following that, get rid of the bedplate mounting bolts, make a note of where the two stud bolts should go and take out the connecting rods, making certain you do not hurt the sealing surface between the bedplate and cylinder block. Because the lower main bearing halves are in the bedplate, you should handle it gently to not fall on them since an improper installation might seriously harm the crankshaft. Lift the bedplate using the cast pry points and once done, remove the crankshaft and the crankshaft tone wheel. If you notice scoring, blueing or heavy scratches inside the connecting rod bearing bores or main bearing bores, extra disassembly may be required. When the bearing bores in the connecting rods are damaged, taking off the cylinder heads is necessary to replace the piston and rod assemblies; damaged bedplate or cylinder block bores call for a new engine. If desired, separate the two main bearing pieces from the front of the cylinder block and main bedplate, clear them of debris, clean all the bearing faces and bores inside the engine and examine the bedplate bore for possible cracks or scoring. Inspect the thrust washers of the crankshaft and look for any splits or visible damage on the oil pan gasket/windage tray. Care should be taken not to harm the bearing surfaces and sealant should be applied to the tone wheel retaining screws before mounting the crankshaft. Apply clean engine oil to the upper main bearing halves, put the crankshaft tone wheel in place and tighten the mounting screws to 15 Nm (11 ft. lbs.). Place the crankshaft in the cylinder block, put the thrust washers on and coat the contact surface area of the bedplate to block with Mopar Engine RTV to avoid leaks. Apply a 2.5 mm (0.100 inch) amount of sealant to the engine block where the bedplate will sit, rub a thin layer of clean oil on the crankshaft journals and set the bedplate on the block. All bedplate retaining bolts should be lubricated with clean engine oil before you install them and as you install them, check that stud bolts are where they are supposed to be and use the correct torque sequence. Place bolts 1D, 1G and 1F until the bedplate touches the block before securing bolts 1A to 1J to 54 Nm, measuring by Nm or ft. lbs. Then, turn bolts 1 - 8 to 7 Nm, 90° further and finish with bolts A - E, set to 27 Nm. First, check the crankshaft end play, then add the connecting rods, measure side clearance and add the oil pump and engine.
