  Q: How Are Rod Bearings Properly Serviced and Repaired on Chrysler Concorde?

  A:

  For bearing service and repair, use the usual routine that covers machining and fitting needed for an engine overhaul, involving the cylinder block, cylinder bore, connecting rod and bearings, Crankshaft and bearings, valve train elements, changing the oil and fitting Pistons and rings. Assembling and disassembling the unit's subassemblies involves service for the cylinder head, the cylinder block, hydraulic tappets if present, oil pump and valves. Procedures focused on cleaning and inspection include the cylinder head, the cylinder block, the Camshaft and its journals, the crankshaft and its journals, intake and Exhaust Manifolds and components of the valve train. If no separate procedure is listed for a particular internal engine part, it means the manufacturer did not supply one.

  Q: What Precautions Are Essential for Proper Rod Bearing Installation to Prevent Engine Damage on Chrysler Concorde?

  A:

  Work on one bank at a time, putting all the connecting rods in place and make sure to notice how the bearing caps are labeled when removing them so you can assemble everything right. You should avoid any damage to the fractured rod and cap joint face so that the engine remains unharmed. Slide the bearing rings up on both rods, so that the tangs are fitted into the holes in the ends of all the rods and caps. Position the cap on the same side as the rod so that the hole in the upper bearing half is aligned with the oil squirt hole. To keep the engine safe, it's important that the hole in the upper half of the bearing matches the hole in the connecting rod. It is best to observe a maximum layer thickness of 0.015 mm or less on any crankshaft journal. Suitable bearings for this include those in 0.250 mm, 0.025 mm and 0.0006 inch undersize. When putting in the bearings, set one pair at a time, never use a fresh half with an old one and don't change or file anything. When checking Main Bearing Clearance and Connecting Rod Bearing Clearance, follow the instructions in Engine Specifications and use plastigage. Before you re-use a bolt, look for signs of stretching; if the threads are damaged, then replace it. Connecting rod bolts sit in the rod cap with a slight press fit, so use a hammer and punch to drive them out when removal is needed and avoid disturbing the screwed cap. If the scale or straight edge holds away from some of the threads, you should replace the connecting rod bolt. First, grease the threads of the screws with engine oil, put the bolts together by hand and then tighten each nut alternately until everything is in place. Put a dial indicator on a still point on the engine, so that its probe is resting against and perpendicular to the connecting rod cap being inspected. Shift the connecting rod to its furthest backstop, put the dial indicator at zero and then bring the connecting rod to its front stop and measure the dial indicator. Make sure the connecting rod's measurement matches the literature value by repeating the process on every connecting rod, as you rotate the crankshaft for accessibility.
