Piston Ring Placement????

Newbie...first rebuild.

I purchased a set of Sealed Power Rings #E-251K-40 from Summit. The install directions show the top ring as having a inner top bevel or a outer tapered face and the second ring as having a inner bottom bevel (depending on the kit). The set does include rings with a inner bottom bevel so I suppose these are the second groove rings however the other set of rings in the kit have no taper or bevel at all. So, by way of elimination the squared (plain, no bevel, no taper) ring must be the top groove ring. Does this seem correct? The rings I removed from the pistons both have inner bevels. Top ring is beveled on top and the second ring is beveled on bottom.

Thanks
Willy

Hello Willy, is there a mark of any kind on the ring showing "up"? If not, I'd use another set of rings that are properly marked. Trust nobody.

"Top ring is beveled on top and the second ring is beveled on bottom."
That's the way I remember it.

It is common for that set of rings.. The top ring is a plain ring. Unlike Hastings and others. No markings. Installs either side up. Second ring has a dot on top side.. Dot up..

Look VERY carefully at the second ring for the pip mark (aka "dot"). It's there, maybe an inch or slightly less from the end of the ring- just hard to see compared to the top ring's pip (if present).

I believe I've been misunderstood. The issue is not which side goes up. Both sets are marked with the dot for top side. No problem. The issue is top groove and second groove on the piston. The install instructions show (diagram) two sets of rings with beveled edges. But the box has one set with beveled edge and one set squared, no beveled edge. I want to make sure i put the compression rings in the top grooves.

Ring w/inner bottom bevel is the second compression ring. The other is (obviously) the top ring.
