520HC 207 #2 Posted June 25, 2010 yes they are the same. I would buy them from a Kohler Dealer. Share this post Link to post Share on other sites
FarmerJim 5 #3 Posted June 27, 2010 I just overhauled a k301 and the original main bearings in mine were stamped with the I-H (International Harvester) logo. After inquiring about the price from my friendly kohler dealer and recovering from the sticker shock, I went to my local I-H dealer and ordered them at ONE HALF the price that kohler wants :thumbs: Share this post Link to post Share on other sites
