Okay, this morphidite engine i'm working on is giving me fits...here's what i've found so far. Maybe someone can shed some light on what I actually have. This was a 1940 distillate tractor to begin with, but has had the engine replaced at some time. The head is casting # 6186DD... my older parts book doesn't show it. It does have the 43912D and 43913D kerosene valves in it. The bore mics at 3.443 + or - .002
The piston skirt mics at 3.431, and the top at 3.414 The block # is the 6397DF 1.This appears to be a 3 7/16 (3.4375") bore to begin with, and has about .068" wear. The ring gap was considerable, but there was very little ridge in the cylinder. 2.The valves were very carboned up. I had done a compression test and got only 55 lbs. 57lbs, when I added oil. The tractor burned oil and fouled plugs quickly and I suspect it was mostly in the valve train. 3. I'm considering getting new pistons and sleeves while I have it apart, but am not sure what to get. With the distillate head, I'd guess it would have lower compression. It currently has flat head pistons in it. Would dome head pistons give much power increase and can they be used in conjunction with the distillate head? 4. The valve length was almost exactly 5" with the exception of one that was about 5.2" long... it did not have the IH part # and must have been replaced at some point. Can the distillate head be reworked for gasoline valves? The parts kits i've seen mostly show 5 5/16" or 5 15/32" long valves. If I replace EVERYTHING,valves, guides, springs etc, is there any reason I could not have the valves listed in the kits? It appears there is no difference in pushrods, or camshaft for gasoline vs Distillate tractors. any help would be appreciated.... my hair is thinning as it is... I really don't need any more reasons to pull what is remaining out!

Talk of the Town: How to Remove a Broken Bolt - by Staff. Another neat discussion from the Tractor Talk Discussion Forum. The discussion started out with the following post: "I have an aluminum steering gear housing with a bolt broken off in it. The bolt is about a 3/8" x 1 1/2" bolt. I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
