  Q: How is a Crankshaft Installed in an Engine on Chrysler Pacifica?

  A:

  First, properly lubricate both sides of the crankshaft main bearing with engine oil and then fitted them within the engine block. Install the crankshaft in the engine block and perform the fitting of the main bearings. Check the main cap bolts to make sure they are not stretched and swap out any that have stretched; if the threads do not contact a scale or straight edge, that bolt should be changed. Tighten the main bearing caps and bolts to 41 Nm and then add an additional 1/4 turn before using new washer and cross bolt assemblies during assembly. Set the screw tightness of all the new cross bolts and washers to 61 Nm. After that, fit and mount the connecting rod and bearing caps on the crankshaft. Put the crankshaft rear oil seal in first and then place the crankshaft sprocket. After that, place the Timing Chain in its housing and fit the camshaft sprocket on the end of the camshaft. Now, install the timing chain cover. Then, attach the oil pick-up tube and Oil Pan, fit the transaxle to the bottom of the engine and finish by mounting the engine assembly.

  Q: How to Safely Extract the Crankshaft from an Engine on Chrysler Pacifica?

  A:

  First, undo the bolts on the engine and take it out before removing the transaxle from it. Put the engine on a stand, then remove the Oil Filter, the Oil Pan and the oil pick-up tube. After that, take out the Timing Chain cover and then remove both the timing chain and sprockets. Take out the rear oil seal and retainer for the crankshaft, remembering never to change or mix the connecting rod caps, because the 3.8L may have a mix of standard forged or cracked caps. When the connecting rod cap can be turned, make a mark or a scribe on it and then remove the cap very carefully to avoid harming the crankshaft bearing surfaces. Do this same process for all of the connecting rod caps. With reassembly, discard the main bearing bolts and washers and then attach new assemblies instead. First, loosen and take off the main bearing cap bolts, then remove both parts of the main bearing caps and at last remove the crankshaft from the engine block.
