assuming that you have new cylinder liners and pistons or old pistons with good ring groove conditions, piston rings come with the correct/specified clearance when bought new.

How you can masure the piston ring side clearance?

To measure the piston ring side clearance, first, install the piston ring onto the piston and place them in the cylinder bore. Use a feeler gauge to measure the gap between the ends of the ring when it is positioned in the bore. The thickness of the feeler gauge that fits snugly in the gap indicates the side clearance. Ensure that the measurements are taken at multiple points for accuracy, as the clearance can vary due to wear or manufacturing tolerances.


What causes the piston ring groove clearance to widen in service?

As the piston moves up and down in the cylinder it also moves the piston rings up and down in the grooves. With the rings moving up and down it gradually increases the side clearence. Material is taken off from both the piston groove and the ring.

How do you install piston rings?

The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.
