  Q: How to Remove and Replace a Piston and Its Connecting Rod on Dodge Sprinter 3500?

  A:

  Bolts on the negative Battery Cable and then remove the cylinder once it is removed. Lift the vehicle up on a hoist and remove the Oil Pan which includes the oil pump pickup tube. Take out the ridge reamer and clean the top of the cylinder bores until they're smooth, but always make sure the top of the pistons are covered during this step. You should remove the pistons and connecting rods from the block by rotating the Crankshaft so that the connecting rods are centered in the bores, maintaining care so as not to scratch or nick the crankshaft journals. As soon as the worn particles are removed, place a bearing cap over the right rod and mark the pistons according to their respective cylinder numbers. When removing the piston pin, put the connecting rods in a soft jawed vice, remove both of the snap rings fixing the pin and push the pin out of position. When taking out the piston rings, place the ID marks on the top and second rings so they are toward the piston crown and remove first the top and second piston rings with a suitable expander, then the upper rail and lower rail of the lower oil ring and finally the oil expander from the piston. Lastly, wipe the carbon off the pistons' crowns, skirts and ring area, so all four holes in the oil control ring are opened.

  Q: How to Install and Replace a Piston and Connecting Rod on Dodge Sprinter 3500?

  A:

  Secure the connecting rod in a soft jawed vice and apply lubricant on both the piston pin and piston before putting them in place. Piston must be placed inside the connecting rod so the piston's arrow points away from the bearing cap's numbers. After that, fit the piston pin and attach clips on both sides. When installing piston rings, place the chromium-plated, top tapered ring first, using a suitable ring expander to align the second scraper ring's edge at the base of the piston and the oil control ring as well. Set up your rings so that the #3 slot contains the top ring gap, the #1 slot holds the second ring gap and the oil control ring belongs in the #2 slot. Put back all the parts in the same location as before, with engine cylinders numbered opposite to the gear transmition and make sure the arrow on the piston faces the front. Place a ring compressor around the cylinder and make sure the oil ring expander ends and the piston rings are both on the bottom of the cylinder. Close the compressor after providing clean oil to immerse the piston and rings. Turn the crankshaft so the rod's journal is in the middle of the cylinder bore, place the rod and piston through that journal, guide the rod over the crankshaft journal and drive the piston in with the hammer handle as you position the connecting rod on the journal. Assemble the cylinder head and balance shaft, make sure the oil pump pickup tube is connected and then fit the Oil Pan. Before turning the engine back on, reconnect the negative battery lead. Keep in mind that rods cannot be removed from the connection, so whenever you take out the bolts to maintain precision, you need to replace the rods.
