Im replacing piston rings on my DYT 4000 18.5 HP OHV. Although the replacement rings i order based on model # do not fit, also oil ring is different style. I have exhausted myself trying to identify the exact set of rings needed and honestly could use some help if anyone has a clue. Thanks in advance.

Looking at the Briggs IPL, it shows 1 part number for standard (594437) but when you get into the .020" over rings, thats where the date codes come into play. .020'' over only if you bore the cylinder. and you also need a .020 over piston.
and it appears you got the correct ones.

So, are they not fitting on the piston, or are they not going into the cylinder bore?
Hello I had that same engine with the same problem. One of the valve’s got stuck open on the heads as well.
That’s the engine that they paid a settlement on it. I end up junk it and replacing with a B&S 19 hp. Good luck with it.
