clintonnut 126 #2 Posted May 28, 2010 Just pull the head off and if the exhaust valve is smaller than the intake valve then you know what to get. The smaller one is 1 1/8 and the bigger one is the same size as the intake valve and measures 1 3/8. The measurements are the diameter of the face of the valve.

rmaynard 15,961 #3 Posted May 28, 2010 With your model and spec number in hand, go to the Kohler parts look-up and it should tell you what valve you need. Kohler Parts Lookup Bob Share this post Link to post Share on other sites
