I have herd that when the 450 came out that the many had problems with the engine and transmission, What problems did you experance with this tractor? also did the timing gears wear out from driving the hydrolic (spelling) pump on the timing gear?

Spent a great deal of time on a Farmall 450 diesel. We farmed 300 acres with it and a John Deere 70 diesel. They were pretty well matched for power. We plowed day after day following each other. Of course the Farmall 450 had to have the torque pulled while the John Deere 70 lugged right on though. Problems ... Well, like was said the hydraulics are weak. The pumps go out. The levers get loose. The steering is more like power steering assist. Nothing like the JD 70 .. it always had good steering and hydraulics. The steering shaft went through the radiator. If not alined right it wore holes in the radiator. The torque went out once while we had it. On the diesel the heads were prone to crack. Remember doing that once. Bearing went out in the rear end. Not enough clearance between the casting and the bull gears. Pushed open the bottom of the rearend once. Also, pushed a hole in the transmission case with the same kind of bearing problem. The Deere never really had any of these problems. The 450 was a faster tractor and probably more modern with the foot clutch. People complain about the torque .... but for all the times we used it the little repairs it took was worth it. It handled tasks like pulling the rotary hoe much better due to its speed and the torque. Both were good tractors in their own way.

There is an issue with the timing gear coming loose from the cam shaft. New cam shafts have LH threads and are less prone to loosening up. The priority valve for the power steering is another common area for a problem. I have not really heard of to many tranny problems, but I am sure it was an issue as when they went to the 560 all heck broke loose. And they do like gasoline, but they will pull like an ox.

I had a 450 Gas for a few years and the only problems I had with it was the hydraulics. They were very weak and the power steering would only work half of the time. I have read several posts about a "saftey block" valve that gives priority to the steering and if that valve wears out you have hydraulic problems. I didn't fix mine and sold it to buy the 656D that I have now. I also rebuilt the engine in mine and it had tons of power after that. Was a good tractor overall, but I wanted something more modern. I love my 656, but I wish I had the 450 back for lighter work.

There were some problems with the final drive gears, never heard about problems with the gas engines. The Diesels were IH's start-on-gas engines with the usual problems and advantages.
