Well, I finally went and got my little C that I bought. Bought it pretty reasonable because it has some engine problems. It runs , but I haven't heard growling and knocking like that since the last presidential debate! Didn't get much time to play with it , but I had just enough time to pull the valve cover and the oil pan. Top end had some slighlty bent pushrods. I didn't get a chance to pull the bearing caps yet , but I found there was oodles & gobs of crankshaft end play. I also saw that someone had been in there before me as one piston and rod was new. Does anyone know what the crank endplay supposed to be? Is this corrected by the bearings on these little tractors or on having the crank reworked? This tractor ought to be a fun little project. I have overhauled lots of tractors (D17's, Ford 861's, 8n's, IH 1086's...)but this will be the first I have worked on where shims are used to set the clearance. Wish me Luck!
