| I am freshening up a cast iron 16HP Briggs engine, and I removed the piston which is stamped .010 over, and have discovered that I can't get .010 piston rings for some reason. I have not removed the old rings from the piston as of yet. When I put a standard ring in the cylinder, the end gap is way out of tolerance. I am wondering if I can reuse the old rings? I have given the cylinder a quick hone to break the glaze. Thanks for the input. Thanks for the space. |

Was the head clean inside? Was there good compression? Was it NOT buring oil ? If , I'd reuse the rings...cause if it ran fine before you tore it apart ,it'll work fine now. ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

| It was a decent running engine a few years ago. The head did have some carbon on it, and I have cleaned it up. I am putting this engine in a B110 for some stock tractor pulling The proper route would be to hog it out to .020 over and put the .020 rings in it that I can get new. |

| I forgot to mention that there was a wee bit of side play of the piston in the cylinder, but not much. I have seen a lot worse! LOL. |

I don’t know what it takes to get NAPA to order some through Hastings or Perfect Circle, but there was a phone number to Hastings. I would guess you could get by with the old rings, but new ones would be a good improvement. |

| Just a thought but why not .020 over and file fit on the rings ? |

Agree with AC720, file a set of .020 to fit. Gary |

| Dumb question, guys, but I will ask it anyways...lol....Do I just have to file the end gap to the proper tolerance? Thanks. |

| Make sure you lube the rings real good, and that's from the guy who believes in dry ringing an engine. The reason? Because you're going to be putting a lot more pressure on everything. I've done it myself and it worked perfectly. Spin it over with the plugs out for 5-10 seconds, then put them in and start it. Don't rev it up just let it run until you feel the heat build up, kill it and let cool out. If it spins free by hand, next time run it longer and a little harder. Let cool again and you should be good to go. You'll get pride out of making it go. Let us know. Leon |

| PS. Check your oil for metal specks before running it very hard. No use in loosing what you already have. |

| Good idea, Leon. It won't be hard to drain it out and check it. |

PSS Well for a lot of us we're well past retirement age and most of us are limited on how much we can do and how hard we can work. We may not be real current with our memories but we're pretty darn good at the old times and we have a lot of experience to pull from. My plan had been to help the widows with children, old folks and the poor to maintain their vehicles free of charge for the labor. Well, I got to help a few but a couple of tick bites put the skids to me close to ten yrs. ago. I can do a little bit and maybe gaining a little, but it's a long haul. I like to see younger ones and the inexperienced expand their imagination to fix things and have fun doing it. And fishing isn't a bad occupation either. LOL |

KevinON, just a note on rings be sure and get the required clearance you need from ring maker, to much clearance and you'll have leakage past rings and to little clearance and rings will seize as heat increases. Every manufacturer has a set standard on file fitting for their products. Leon sorry to hear about bites, I know we all have ideas of things we want to accomplish in life, enjoy the fishin won't find a much better cure. |
