Tim. I have a question for you about this very topic of an in frame overhaul on a 4230. I fellow I have gotten to know the past few years had suggested there were some differences between the piston design on Deere's overhaul kits versus others. The key point he made was the piston design through Deere upped the compression ratio a bit, as well as trueing up the head, made cold weather starting better on the 30 series. Is there any truth to that statement? I remember on our 4630, after the sleeves and pistons were replaced (through a Deere dealership), the valves all replaced, and the head was planed, this cold blooded tractor really changed for the better in its ability to start. You knew in the first couple revolutions of the engine, if it was going to start. It starts quite a bit better than our 4640. One additional note: When in doubt about starting in cold weather, we simply plug the block heater in.
