Default Huston I have a problem... Wisconsin AEN Rings

Well I ordered parts today for my Wisconsin AEN and I started reassembling parts. I cleaned the piston and the rings and then I noticed NO dots or bevels on the rings. None. And the rings DON'T look like the ones in the Wisconsin pdf file. The oil ring has one sharp scraper side? no difference in the other three. So should I install the oil ring sharp side down?

Thanks,
Mike

Does one of the compression rings have a notch cut around the outside? If so, that one should be just above the oil ring and the notch should be on the bottom. I would put the sharp side of the oil ring down or it will push oil up instead of back to the crankcase.

Ok I did that with the oil ring, but there are NO differences in the compression rings.

Is there a bevel on the INSIDE of any of the rings? If so, that one goes on top, bevel side down. The bevel acts to press the ring outward under compression, to help seal the cylinder If all compression rings are identical in appearance, then it should not matter where they go on the piston.

Sorry to quibble...

I had to give myself a sanity check by checking a manual (Wisconsin AGND in this instance; first one that came to hand) to be sure but yes, for one rare moment my memory served me well. Compression rings that are beveled on the inside are installed with the bevel UP not down. I can't say for sure but I always thought that this was done in such a way so that any compression that leaked down the side of the piston and got in the back side of the ring would press the ring out and down to help sealing. But that and $5 might get you a cup of coffee at one of those fancy pants places.

My rings are the ones that were on the piston when I got the engine they are not replacements. All three compression rings are the exact same no dots, bevels, no nothing. The oil control ring is the only one that was different, and NOT like the one in the ANEL pdf file.

Thanks and God bless.

s100 is correct, inside bevel goes UP and outside scraper goes DOWN
