Hi Gramps, Engines are funny things and don't follow the rules as they are written down or as we think of them & how they wear. :>) After a gasoline engine is brought up to tempreature, for all intents and purposes, there is no wear whatsoever. The wear comes when it is started cold and also if it is allowed to idle for long periods of time. These are the times when the upper cylinder walls are least likely to get lubrication. That's why most of these old tractors were designed with updraft fuel systems. They are designed to keep that fuel to a minimum while the choke is being used and the engine is cold. Raw fuel washes lube away from that cold cylinder wall. So, you can see that you really cannot compare engines in cars with engines in a tractor. You would never want to buy a used car where it's previous owner "Was a little old lady who just drove the car down to the post office and to church". That car has had a terrible life. Car engines are abused in the worst possible way plus the fact that they are allowed to rev much, much higher than your tractor's engine. You never hear of a car's engine lasting for over 50 years, but there are many tractors out there which have worked hard all their life and are still going strong. I would venture that many of these old tractors have upwards of 10,000 hard working hours on them. So, if your tractor's engine is running fine, not making any unusual noises and not using oil, I would not even worry about it. Just ignore that hour meter and keep on keepin' on. Allan
