WrenchinOnIt posted a long (thorough) comment on the mechanical procedure for cleaning the K582 in an HT23. He even gives part numbers! Reply #13 and the thread is here: http://gardentractor...-oh/?hl= uh oh
Hi Paul , a few more details , YouTube has vids of lapping valves if you decide to go that route .I use various diameters of soft wire wheels in a variable speed drill.I like the cup style for top of the piston, and the wheel type for the heads I have found the die grinder even with soft brushes is to aggressive. A dremel ( or similar) with an assortment of wire brushes is handy to get in the tight spots.
When you compress the valve spring it will push the valve out slightly rap it with a soft faced mallet to pop the valve keepers , one of those small strong magnets on a telescoping wand is handy for retrieval of them out of the oil gallery.
When I pull the valve I chuck it into a battery drill get it spinning and use the bench grinder with a wire wheel mounted, the valve spinning against the rotating wire wheel on the bench grinder makes them as clean as new.
After the lapping is done a very thorough cleaning is a must, you should change the oil anyways (IMO) after procedure is complete, I like the green can of NAPA (CRC) brake cleaner it will blast the crud and the grinding compound out and the smell of it won't drive you out of the garage.
A good tip mentioned several times here by others is a dab of grease on the keepers when reinstalling will hold them in place, the magnet on the wand will help you place them where you want them.
Valve adjustment is valves closed compression stroke, 360 after TDC following exhaust stroke, rotating the clevis clamp to the 11 o'clock position but only if it's going to be a full moon, HUH! WTF! Yea really ,I need stuff K.I.S.S. cause I can be at times.. so do all the valves first , keep the heads off , do the valves one at a time when they're all complete and back in rotate the flywheel till what ever cylinder your on comes to the end of the jug all the way to flush ( or close you'll see as you stroke it thru a revolution) TDC,the valves will be closed,if you reach into the valve stem/tappet galley are the tappets tight against the valves? Can you rotate the tappet? If not rotate the flywheel till the piston makes another revolution to TDC,valves will still be closed, but now the tappets are loose ,get out your feeler gauge and adj. if necessary.
Last check this out , did a couple heads this way before reassembly the machinist that does block work for me suggested this method ,said it makes a difference, he is old school so if he said try it that was good enough for me. I'm anxious to see the results on how they run, if I ever get the tractors done! If you want pics i'll pull a head and take some.http://www.jeremiahs...com/grooves.htm
PS, volume off on YouTube, unless you want some rap is crap stuck in your head
