FE290 Piston Ring Order

[DrLenger]

Finally got my block back....all bored and ready to go....one problem, I can't tell which piston ring is the top and which is the middle. The FE290 manual looks like the #1 or top position is rounded, while the #2 or middle position is angled. But looking at the new rings I can't tell which is which, one is black finished on the edge while the other looks machined. I know the side with the markings goes to the top, but how do I know which is which.....HELP!

I am excited to get this thing back together, but as my previous posts have said ...... patience my son patience.....I don't want to screw this up again.

I just assembled a FE350 and I put the top ring the one with the machined face and the black finished one in the second groove.

When you install the rings, remember to index them.

got it......I am a little concerned the one that has the machined edge appears to be the scraper, or 2nd position, while the black or unfinished edge seems to be the bevel



see in the clip from the FE290 Engine Manual how the edges of the rings are.....?????

I saw that too in my manual, but I couldn't see those outer shapes no matter how long I tried to find them. Thus, made a decision and went with what made the most sence to me.

I did the same, I looked and looked, even broke out the magnifying glass, still nothing. So I used my best judgement and went for it......it worked out, seems to run just fine.
