The instructions say .003 to .004 per inch of cylinder diameter. Calculates out to .011” to .015”. What end gap should I use? Anyone used this combination?
Thanks, Jsaum |

.017" is good, if you're over a hair I wouldn't worry about it.
You don't really have to stagger the gaps, as the rings spin in the grooves, but old habits die hard so I still do. On the oil scraper do have the gaps 180 from each other and the wavy ring 90 degrees from the gaps. These rings do have bigger gaps right out of the box, don't worry about it. With grant rings care must be taken on the wavy ring that you don't overlap the ends, you must see both painted colours on the ends once installed. After grinding lightly deburr with a jewelers file, but only enough to remove any burrs. I don't know if running .015" on the 2nd ring helps much, but I like to keep gaps as small as possible. Nickies you can run much smaller gaps. |
