  Q: How to Install Piston and Connecting Rod Assemblies on Chrysler Aspen?

  A:

  Install the piston rings first, then immerse the piston head and rings in fresh clean engine oil before putting on the piston and connecting rod assemblies. Place a ring compressor on top of the piston and rings and tighten it slowly, so the rings are not moved out of place. Install the bearing right side up on the connecting rod, line up the bearing hole with the rod and wipe the bearing with clean engine oil. Place Special Tool 8507 Connecting Rod Guides inside the connecting rod bolt threads before assembling. On each piston, an "F" must be visible when looking down the cylinder; both pistons should also show the connecting rod oil slinger facing forward. Clean out the inside of the cylinder, apply a thin coat of engine oil and turn the Crankshaft until the connecting rod journal sits right inside the cylinder. Lower the rod and piston through the bore, push the connecting rod guides over the crankshaft journal, tap the piston and lead the connecting rod into its proper spot. Remember that connecting rod bolts are Torque to Yield Bolts that should not be used again; take care to always replace them when you loosen or remove them. Grease the rod bolts and where the bearing will go with engine oil, then put the cap and the bearing on and tighten them to 27 Nm (20 ft. lbs.) plus 90°. Next, set in the cylinder head(s), fit the Timing Chain and cover, seal the cylinder head covers and secure the Oil Pan with gasket or windage tray. After that, add the proper oil to the crankcase and link the negative battery cable.

  Q: How to Remove and Replace a Piston and Connecting Rod on Chrysler Aspen?

  A:

  First, take out the negative terminal from the battery to detach the cables before moving the piston and connecting rod. After that, take out the Oil Pan and gasket/windage tray, cylinder head covers, timing chain cover and cylinder head(s). If the cylinder bores need it, use a good ridge reamer to remove the top ridge and then take out the pistons with the tops of them still covered. The pistons and connecting rods on top of the cylinder block should be taken out and the Crankshaft must be rotated, so the connecting rods are in the center of the bore. Don't use a number punch or stamp on the connecting rods or their caps to prevent damage. Place marks on the positions of the connecting rods and bearing caps using an indelible marker or scribe, but do not scrape or ruin the joint surfaces still intact. Take off the cap on the connecting rod, place Special Tool 8507 Connecting Rod Guides inside the removed rod and take the piston out of the cylinder bore, repeating the steps for every 1 piston. Be careful not to cut the bore works while installing. Right after removing the piston and connecting rod, set the bearing cap over the mating connecting rod to prevent damage to the broken cap and rod pieces. You should carefully removed the piston rings from the pistons, starting with the ring that fits the piston head first.
