I received no instructions for these rings and have not seen any like them on YouTube. I have never worked with similar rings.

Piston Ring Placement



It has been a while since I received them and I am not 100% sure how they were arranged in the boxes. I am fairly confident that they are placed in the boxes now as they were from the factory.

Piston Ring Placement



The compression rings are not marked as "Top" or with a dot as I am used to seeing. There is not a pronounced chamfer on the inner edge either side to identify the top. There are numbers on one side and there is a barely perceptible break of the inner edge on the numbered side. The reverse side has a very shape inner edge. One compression ring appears to be chrome/steel while the other appears that it might be cast iron.

I am fairly confident that the numbered side is "up" and the chrome steel ring goes in the top ring groove on the piston.

Can anyone that has experience with these type rings verify my assumptions?

Of course the usual specs for arranging the gap and minimum end gap would be employed.
