Sparky-(Admin) 21,403 #1 Posted October 18, 2007 Anyone know what the thread size is on a Kohler "K" Series? Saw a used compression gage with 14mm threads only. I'm pretty sure a Kohler is a standard size and not metric. Thanks Mike.... Share this post Link to post Share on other sites
Sparky-(Admin) 21,403 #2 Posted October 18, 2007 Now that I think about it....is a compression gage any use on a "K" Series kohler with Auto Compression Release? Mike....second guessing myself.... Share this post Link to post Share on other sites
nylyon-(Admin) 7,300 #3 Posted October 18, 2007 It should be 14mm, that is the standard plug size even for SAE. Share this post Link to post Share on other sites

Curmudgeon 28 #5 Posted October 18, 2007 Well, you'll get a compression reading, something like 40 pounds, and wonder how it can run. A leak down test would tell you a lot more, but then, it's a lot harder to do too. Me? If it runs, I run it, if it doesn't, I work on it. LOL Dale Share this post Link to post Share on other sites
