OK,
I recently bought an IH574 and although I looked for smoke before I bought it, turns out it smokes like crazy. I've read through most of the messages about smoking diesels and the lack of compression. Although I haven't checked my compression the symptoms certainly point to that being the problem. The question I have is how do I get the compression up? The blow-by is not bad so I'm not sure that the rings are the culprit. What else could it be? I have read things about injectors and aftermarket pistons, but I believe everything in my machine is original.

Any help would be appreciated.

Continual white steady smoke all the time may be as simple as late injection timing.

My original D239 started real easy (even in the winter <32F) and hardly smoked a bit even though it had: spun a bearing; lots of blowby, coolant in the oil, and low oil pressure. The rebuild smoked (unless it was working hard and up to temp) and was noticably difficult to start when outside temps dipped below 50F. I have never had a compression check since it's not trivial equipment-wise, but assume it's the aftermarket stuff since the injectors were rebuilt. Does yours start easy in the cold?

I haven't had the tractor long enough to know how it starts in cold weather. Lowest its gotten to is about 30 so far this year. It seems to start extremely well in warm weather and at about 40 or so it fires after about 3-5 compression cycles. The smoke is continuous white and it NEVER blows black. I have tried to get black smoke and it just doesn't happen.

Brad , I believe there are after market sleeve and piston kits that are available that are higher compression . It seems that the original pistons had higher compression ratios than the replacements that are probably in your engine if it's been rebuilt. If I can find the company that produces these enhanced overhaul kits I will post it .-
