Before installing new piston rings, begin by checking the ring end gaps, while assuming that the piston ring side clearance has been verified as correct. In order for each set to correspond to a specific piston and cylinder, organize the piston/connecting rod assemblies and new ring sets this way. Gently push it down with the top of the piston for squaring up of the first (top) position one ring inside the initial cylinder near its bottom with its walls. The right gap width should be found by using feeler gauges inserted between the ends of the rings until it can be slid on them with just a little bit of pull. Check this measurement against specifications to make sure it's in range. Check if they are not too small or large enough in case you have chosen wrong ones or if necessary, file accurately their ends and adjust this size of clearance. Double-check compatibility when end gaps exceed 0.040 inches. This should be repeated for all rings intended for every cylinder while maintaining proper pairings during this process. Rings are then installed after checking and adjusting end gaps. These three components constitute an oil control ring that is installed by putting a spacer/expander into a groove and aligning an anti-rotation tang (if present) with a hole drilled in a ring groove. Use no tool for side rail installation below or above while doing so. When inserting both upper and lower side rails into the ring groove, ensure they move freely there within that space. The middle (number two) generally marked ring must be installed utilizing a plug installation tool with its mark facing upwards'. Ring packages should follow maker's instructions; don't mix up top and middle rings that have different cross sections.' Ensure that you put number one (top) ring on indicating direction upwards and see to it that you have distinguished it from number two (middle) ring.' For top rings without marks on later model engines, it can be placed in any direction. This process should be repeated for the rest of the pistons and rings while keeping accurate pairings.
