How to Check Clearances and Install a Piston Ring Set Before Reinstallation on Jeep Commander?

Always clean the cylinder bore, put in the ring and measure the gap at the part of the ring where it is at least 12 mm (0.50 inches) above the bottom of the bore. Place the ring inside the cylinder by pushing it down with a piston, checking that it is squared before measuring the end gap with a feeler gauge and changing any ring with a gap that is not right. Always check the grooves for piston rings, making sure they are clean and nicks are removed before measuring, inserting a feeler gauge and replacing the ones that are out of specification. Turn the ring as it sits on the piston to check it does not jam and remember that the manufacturer's Dot should face the top of the piston when installing the No. 2 ring. Place the oil ring expander on top, followed by the upper oil ring side rail by sliding one end into the expander ring and the piston's groove, squeezing it down into position. Then, do the same for the lower side rail as well. Install the No. 2 intermediate piston ring and the No. 1 upper piston ring using a piston ring installer, with all end gaps in correct position, the expander ring gap at least 45° from the side rail gaps and not in the thrust direction or on the piston pin center.
