  Q: How to Remove and Install a Crankshaft in an Engine on Chrysler Concorde?

  A:

  The first step is to take the engine out from the vehicle and set it on an engine stand. Take out the old engine oil using a drain pan, change the Oil Filter and remove the Oil Pan and oil pick-up tube after that. After that, remove the bracket for the accessory Drive Belt, the upper Intake Manifold and the cylinder head covers. Uncover the Timing Chain, replace the primary chain, remove both tensioners, the crankshaft sprocket, oil pump and the rear crankshaft oil seal retainer. After that, remove the structural windage tray. Move the crankshaft so you can take out the connecting rod cap and remember to mark the connecting rod bearing caps with a permanent ink marker or scribe tool, since they don't fit every engine. Prevent the damage of the connecting rods by not using a number stamp or punch. Be careful to take out the bearing caps and the bolts that hold them before you remove the main bearing caps. Do not damage the bearings when you remove the crankshaft. Use engine oil to coat the upper main bearing halves and then install the crankshaft, so the coated and grooved side of the thrust washer is turned toward where the crankshaft will press against it during operation. Push the crankshaft towards the front to install the front thrust washer and then press it back to set the rear thrust washer, each lubricated. Apply engine oil to the lower main bearings, slide in the main bearings and caps and make sure you grease the main bearing cap bolts before installation. Do up the main cap bolts on the inside to 20 Nm + 1/4 Turn, then measure the crankshaft for play and install the rods and check their side clearance. Place the windage tray in position, give the bolts a coat of oil and tighten by 27 Nm + 1/4 turn. Put all of the oil seals, sprockets and chain onto the crankshaft, then screw the main tie bolts to 28 Nm. After everything is checked, reinstall the engine and add the needed amount of oil to the crankcase.
