Hi All
I received a few new sets of Standard Piston rings and was looking to determine their Orientation.
The top and 2nd ring have both got a Capital R which I assume is Riken. All OK
The challenge is which is the top ring and which is second. I have looked at all the guides and think the following
image 516 and 515 are of both rings with an R to be faced upwards
image 514 and 513 are the same ring from either side of the ring. I think this is top ring. It also looks lighter than the other ring...
Image 512 is the second ring I think but seems to have 90 degree sides.... IS That right..
Thanks

Top ring (compression) is the light coloured ring, 2nd ring is the dark coloured ring (scraper) , all markings facing upwards.
Here is a pic of my Cruzinimage 400/4 pistons / rings.
