Crmaverick 91 #1 Posted January 13, 2021 Is there’s an interval that these Kohler K series heads should be removed and decarboned? And check the cylinder / deglaze with scotch brite if needed? Curious if that’s something a lot of people do when they get a new tractor, or every so often just as a preventative. Share this post Link to post Share on other sites
ebinmaine 63,133 #2 Posted January 13, 2021 I'm not sure if there's an actual service maintenance interval on something like that. We've done three or four. All of them were because we had the rest of the externals off the engine for painting so that's obviously the easiest time to do something like that. 2 Share this post Link to post Share on other sites
richmondred01 2,205 #3 Posted January 13, 2021 There is no scheduled decarb for the Kohler engines (k and magnum series) unlike the onans. However, for the cost of a head gasket, it’s not a bad idea to inspect one you just procured. That way you will know what you are starting with and what you may expect down the road. While you have the head off it may be a good time to check for warpage and level the head. Here’s the torque sequence. 1 Share this post Link to post Share on other sites

Good to know is deglazing with scotch brite a good idea with the piston still in there? Share this post Link to post Share on other sites

richmondred01 2,205 #6 Posted January 13, 2021 Nope. use a hone to deglaze however, the piston and crank should be out of the engine when you hone. 3 Share this post Link to post Share on other sites
