Hi all,My wife finally gave me the OK to start my '45 2N restoration and I have a few questions. First a little background info.... it's a '45 model 2N pretty much original. The generator is missing and the wiring has been "re-done" several times during the tractors life. It was left covered non-running for the past 8 years and I towed it home a few months ago. I drained all the fluids, did some initial cleanup and solved the no spark problems. The engine had very poor compression on #3 & #4 and the compression didn't change appreciably when I added oil to the cylinder. I was able to get it to "pop" a few times but never successfully got it started. I pulled the head and found that I could move the pistons side to side quite easily, far beyond the factory specs. At this point I decided to do a full restoration on the tractor and started disassembly. The motor is now on the engine stand and I've started sandblasting the chasis. The sheetmetal was just sent out today for chemical stripping. OK, on to the questions : 1) how do you remove & replace the sleeves in the engine ? 2) the main & rod bearings show little if any wear so I'll assume they've been replaced at one time or another. How can I tell if they are .002 (or larger) oversized ? There appears to be no "extra" markings on them. (i.e. car bearings generally are stamped .010, .020, etc.) I plan on replacing them anyway as long as the engine is apart. 3) what are "rotating" & "non-rotating" valves, which is better, and how can I tell which I have ? If it matters, my tappets have adjusting nuts on them. 4) what are the angle(s) of the valves & seats? Also, should I be looking at replacing the seats with something newer due to the no-lead gas? Again, in 60's cars replacing the valve seats is commonly done to stop valve burning due to no-lead gas. 5) What is the best primer to use on the chassis after it's sandblasted clean of paint & sludge? 6) I'm planning on using car paint (PPG) of the sheetmetal, but what should I use on the chassis & engine? Do I need a high-temp paint on the engine block? Whew, that was longer than I thought it would be! Any help that you all could provide would be greatly appreciated ! Thanks, Bob
