Question 1

How is the Crankshaft Installed on Chrysler 300?

Accepted Answer

Make sure the upper and lower bearing halves are different and that you use select fit main bearings when mounting the crankshaft. Always start by installing the upper crankshaft bearings at the top of the cylinder block, checking their tangs fit into the slots and that the oil passages are correctly matched. Coat the upper main bearing halves with engine oil before you begin installing the crankshaft so you don't damage the bearings. Fit the crankshaft, placing the thrust washer block onto the machine's thrust surface with its coated and oil groove facing upward. Roll the front thrust washer onto the machined area between the No. 3 upper main bulkhead and the crankshaft with a crankshaft rotation forward. Set the crankshaft back into position, put on the grease and insert the rear thrust washer as outlined above. Set up the main bearings into the main bearing caps and pour clean engine oil onto them, then lubricate the bolts on the main bearing caps. Put each major cap into place and just finger-tighten the bolts inside, making the reference marks on the #3 main bearing cap align. Place the #3 main bearing cap on the block, so that it is level over the inner bolts, then tighten the inner bolts to 20 Nm (15 ft. lbs.). Move the crankshaft forward until the space between the #3 main cap and the crankshaft thrust face reaches at least 0.25 mm (0.010 inch). If space is too small, adjust the #3 main bearing cap into a new position. Once you're sure the main bearing is centered, tighten the inner bolts on the main bearing cap an extra 90° turn. With the crankshaft supported, find the end play then put in the connecting rods and test their side clearance. First tighten the inner main cap bolts, then windage tray bolts and finally, the main cap tie bolts. Set up the windage tray by aligning the slots to the right-hand side of the engine; stick the bolts onto it, then install and tighten to a torque of 27 Nm + 90° turn. Attach the main cap tie bolts and fasten them to 28 Nm (250 in. lbs.). Replace the rear crankshaft seal retainer, assemble and install the oil seal and then place the oil pump assembly. After installing the pick-up tube and O-ring, tighten the bolts so they have a torque of 28 Nm (250 in. lbs.). Installing the oil pan gasket, oil pan, oil filter, crankshaft sprocket, timing chain, timing chain cover and cylinder head covers is necessary now. Insert the oil dipstick, connect the engine components, measure and put in proper oil level for the crankcase and add coolant as needed. After that, start the engine and look for any sign of leaks.

Question 2

How to Remove and Install Crankshaft and Main Bearings on Chrysler Crossfire?

Accepted Answer

Put the engine on a crane and drain all oil from the engine before starting to disassemble. Then, take off the upper oil pan, the oil pump, the rear crankshaft radial seal and the timing chain, being careful not to twist the connecting rods as you turn the crankshaft. On one side, mark the connecting rod and its bearing cap, remove the bolts that hold them and unscrew the caps without removing the bearings. Disconnect the connecting rods, mark the bearing caps before removing the crankshaft and gently pull out all the crankshaft bearing caps. Following that, take out the main bearing journal cap side bolts, discard the crankshaft main bearing journal cap bolts and pull the crankshaft out of the engine block with the main bearing shells and thrust washers attached. Before setting up the upper bearing shells in their areas, clean the main journals with solvent, let them dry and place the thrust washers into the block. Apply a light coating of engine oil towards the bearing places, slide the crankshaft into the block and fix the lower bearing shells onto the main bearing caps. Replace the M8X75 and M10X90 crankshaft main bearing journal cap bolts first, then put in the main bearing journal caps and tighten them in two stages: 20 Nm on the M8 bolts and a 90° rotate clockwise and likewise for the M10 bolts: 30 Nm with a similar rotate. Replace longer connecting rod bolts, set the connecting rod caps on, then bolt them and the oil pump, upper oil pan, timing chain and finish with a new rear radial seal for the crankshaft.
