Well, I have the engine off and the oil pan off, and I took out what was left of the disintegrated connecting rod, all 743 little tiny pieces of it. As long as I'm going to this much trouble, I'll stick a new piston in there too. I'm thinking I might also want to replace the valves, but can't see offhand how to get them out of there. This is an old Kohler 14hp off a JD 140, circa 1974 or thereabouts.

Do you have to take out the camshaft in order to get the valves out? How might one do that, if one is so inclined?

Thanks gentlemen, appreciate the guidance. Tomorrow is looking like a nice day (55 degress, or so they say), so I think I'll try to get those guys out and pretty up the engine while I wait for new parts. John, best of luck to the kid, and give him a thanks from all of us.

Tom, The Kohler K series engines use valves with a split keeper as John T had stated. The best way to remove them is with a small engine valve spring compressor which can be purchased at most NAPA auto parts stores for about $20. You must remove the breather assembly on the front of the engine. This will access the valve springs. Use the spring compressor and collapse the spring. Sometimes it may be required to give the valve head a tap to break the keepers loose from the retainer. Once loose, remove the keepers from the valve stem. Then the valve can be removed from the top of the engine. I would purchase a Kohler K series manual which will have all the info needed for repair of your engine. Most lawnmower shops have them or can get them for you or you can call Kohler direct. 800-544-2444 or 920-457-4441. Good luck!

Hi Tom, Im not familiar with that particular engine, but most of them small engines have valve "keepers" like two split circular halves that are visible after you compress the valve spring down. Comprerss the spring without the valve stem going down and they will practically fall out. They fit into indents in the ends of the valve stem, and the spring presure holds them together and in place.

Yall take care, Im gonna be gone a week or so. My Marine son Brandon was flying to Kuwait today or tomorrow. God Bless the USA Ol John T Nordhoff
