• Q: How to Install Piston and Connecting Rod Assemblies into the Bore on 2009 Jeep Liberty?

  A: Before fitting the piston and connecting rod into the engine block, first place the piston rings inside the bore. Place the piston and rings face down in oil, cover them with a ring compressor and use it to keep the rings in place. Ensure both the tabs and parting line inside the bearing line up with the slots and main edge of the connecting rod. Put clean engine oil on the part of the engine where the crankshaft bearing is located. Screw the Connecting Rod Guides 8507 on to the threads of the connecting rod bolts. An "F" is stamped on the piston pin bore near each piston, showing the correct direction for installation; the "F" must always be toward the front of the engine and the slinger slot of the connecting rod must point forward. Use engine oil to clean the cylinder bore and then grease it. Crank the engine until the connecting rod journal reaches the middle of the cylinder bore and whatever is in the wrong position, either the rod or the piston, should now be added as you correctly place the connecting rod guides atop the journal. Holding onto the connecting rod, drive the piston back into the cylinder with a hammer handle. When the plunger rods are removed, the bolts are designed as Torque to Yield and can't be tightened. So, you need to install new ones each time the bolts are loosened. Put engine oil on the rod bolts and the bearing surfaces before installing the connecting rod cap and its bearing. Screw the bolts until they reach 27 Nm (20 ft. lbs.) plus 90°, then pull them back to 90°. Put in the cylinder head(s), timing chain and cover, cylinder head covers and oil pan with gasket/windage tray. Put the right engine oil into the crankcase and attach the negative cable to the battery.
