Stagger the gaps so they don't line up.
You will need feeler gauges, a ring spacer and separation tool, the correct specs for their correct placement on the piston and the gap specs.
Piston ring placement is very important to ensure the life of your engine. Check out my bio page for help.
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.
You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.
Yes, you can get a snake bite ring on the first placement
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.
a piston ring is not calibrated. You just slide the new one in place

one ring per piston, the pistons have a groove in it where the ring fits on.
Most commonly the bottom ring will be the Oil Controlring.(Control added by amclaussen.)Oil control ring is correct. It is used to keep the cylinder lubricated as the piston goes up and down. The first two top rings are for compression. However, the 2nd from the top ring is also a wipper ring. Used to keep oil from getting into the combustion chamber.(~Decker)
You mean a piston ring. It seals the gap between the piston and the chamber in your engine
The purpose of a piston ring expander is to make it easier remove and install piston rings. Because of the low torque they use, they help to prevent damage to the piston rings.
