How to Maintain and Fix a Piston in an Engine on 2001 Dodge Ram 1500?

To work on the piston, the first step is to remove the engine, after which take off the cylinder head and oil pan. Take out the top ridge in the cylinders with a durable ridge reamer and be sure the piston tops have a cover during this step. Attach a connecting rod to each connecting rod cap, using the same number found on the engine's side and remove the caps. Then, install the connecting rod bolt guide sets on the bolts. Using the crankshaft, center the connecting rod in BDC, center the connecting rod in its bore in the cylinder block and gently raise up the pistons. Once you have the bearing, put on the bearing cap on the rod it matches. Make sure you stagger the gaps in the compression ring, not making them line up with those of the oil ring rail. You should ensure that the ends of the oil ring expander are squarely joined and that the rail gaps are accurate before using the ring compressor. Place the piston head and rings into engine oil, use Tool C-385 to compress the rings and tighten the tool with the dedicated wrench so the ring positions do not move. Add bolt protectors to the rod bolts using the long one on the numbered end of the connecting rod. Bring the crankshaft to a point where the center of the connecting rod journal is at the center of the cylinder bore and the number on the rod is near the number inside the cylinder bore. Placed the rod and piston inside the cylinder bore, make sure the connecting rod follows the crankshaft journal and use a hammer handle to tap the piston down as you fit the rod into position. Place the notch on the piston toward the front and slide the rod so that the larger piece of the rod chamfer faces the crankshaft fillet. After the rod caps are in, align the connecting rod, cap and cylinder bore numbers and use 61 Nm (45 ft. lbs.) of torque to tighten the oil-covered rod bolt nuts. After that, the oil pan, cylinder head and engine should be placed back in the vehicle.
