jake22si 5 #1 Posted January 17, 2011 The stud broke off the crank on my k301 and I am having it drilled and tapped. Should I go 3/8 or 5/8 on the bolt size? Share this post Link to post Share on other sites
TT-(Moderator) 1,162 #2 Posted January 17, 2011 3/8" - 24 NF Then you can use the OEM Kohler bolt & heavy washer to secure the flywheel - just like the newer engines. :banghead: Share this post Link to post Share on other sites
jake22si 5 #3 Posted January 17, 2011 that sounds good, I just informed my machinest 3/8 is what it will be. :banghead: Share this post Link to post Share on other sites
TT-(Moderator) 1,162 #4 Posted January 17, 2011 In case you are wondering......... The Kohler part number for the bolt is 25 086 24-S and the flat washer is p/n 12 468 03-S Proper torque for the bolt is 40 to 45 ft/lb (lightly oil the threads) Share this post Link to post Share on other sites
