Make sure to inspect the ring clearance before putting in either new or used rings to keep engine components from becoming damaged. Begin by cleaning the bore and install the ring, putting it into the bore so that you can measure the interval with the ring being 12 mm or 0.50 inch above the bottom of the cylinder. Square the ring with a
Piston in the cylinder bore and then lower it. Measure the distance between the ring and groove with a feeler gauge and if it is out of specification, replace the ring. Assemble the ring so both sides are clean and smooth, then check the ring side clearance between the ring and the ring land with a feeler gauge; replace any ring that doesn't fit as specified. Be certain that the marks on the ring face up and push it onto the piston so it remains free as it revolves. First, push the oil ring expander through the hole, then press down the bottom side rail between the expander and the piston ring groove until it's in place and do the same for the upper side rail. Put No. 2 intermediate piston ring and No. 1 upper piston ring in place with the help of a piston ring installer. Place the area between the oil ring expander and 3rd ring at the 5 position, between the oil ring lower part and first rail at the 4 position, between the oil ring upper part and second rail at the 1 position, between the second compression ring and 3rd ring at the 5 position and between the top compression ring and compressor cover at the 2 position.
