I am looking for some additional information on an Oliver 1450 I recently purchased. I have the Fiat diesel engine in it, which runs good. I have already found the local AGCO dealer to be a good resource for parts, available but expensive. I have two questions really.

#1 The hydralics bounce under load. When I lift a three bottom plow for transport the hydralics cycle and the tractor bounces. Any ideas where a neophite mechanic could start to fix this problem?
Is it making the problem worse to continue to use it this way?

#2 The easy question: I haven't been able to find any information on the history of this model. I have found information on just about every other Oliver/White four digit model, but nothing on the 1450. Does anybody know anything about when this model was produced? What is the reliability of the Fait engine? Any help would be appreciated

I recently had quite a time trying to find a waterpump for my dad's Oliver 1450. After searching for about two weeks, I failed even to find a rebuild kit for the leaking waterpump I had.The local John Deere dealer had a rebuild kit for their pumps.With a little bit of modification we can now use my dad's tractor and it don't leak a drop of water.

My Oliver book says they were made from 1967-69 and made in Italy by Fiat. However, in the text it says that in 1966 Fiat made the 1450. "in 1966, the larger Fiat tractor became Oliver's 1450 model. Both the 1250 and 1450 tractors were sent from the plant in Modena, Italy, to Genoa and them by ship to Jacksonville, Florida. Oliver then shipped them to Decatur, Georgia, where American tires and lights were installed and Oliver decals and grilles were added." It has a photo and the caption reads, "The Oliver 1450 diesel, also mde in Italy by Fiat, had an estimated PT) power of 55 horsepower when operated at 1,900 rpm. There tractors were overdesigned, which gave them an extra long lifetime" I guess that last comment must make your day! Hope that h

The bouncing symptoms are most likely due to the Draft Control feature of the tractor. The cycling is normal.

The Fiat models were put out after Oliver was aquired by Agco. They had a few different engines they used, the smaller numbers tended to have a non-counter ballanced diesel which had a shorter life span because of the added wear and tear from the extra motion. Most of the ballanced engines had extremely long life expectantcies and as I remember the only weakness was with a thrust bearing. I don't have my book handy to give dates, but hopefully someone else can give you that.

Also, the Agco/Olivers (sheet metal and everything) will interchange with the Agco/AC tractors. They were all made the same place with some subtle changes and different paint. For instance, an AC 5040 is the exact same thing as an Oliver 1265 and the sheet metal will also interchange with the 1365. So it might help in future scrounging trips to find your tractors "sole mate".

I just read a good description by Llamas on the Ford N board about position control on N tractors, including draft control. Some of this information may be of help to you too.

that bouncing 3pt could indicate a leaking main lift cylinder. The cylinder is inside the rearend of the tractor. The position control on a three point always trys to maintain the three point at the position you set it at with the lever. A heavy load can force the 3pt down, the position control valve and linkage responds by sending oil into the lift cylinder. boink!! up goes the three point, the leak and weight sends it back down and the cycle starts over, boink!! up again. So your tractor is now hoppin up and down. The leak could be in the valve or around the lift piston seals. Draft contol is a clever linkage that lifts the 2 lower arms in response to excessive load on the toplink (upper middle point of the three). It only helps with ground engaging implements like plows, moldboard or chiesel. When the plow sucks in too deep the draft control senses the extra pull on the top link and brings up the arms until the pull eases up. Tractors with this have a big spring, leaf or coil, associated with the top link, which lets it move a bit underload, and some internal or external linkage that sends that info to the position control valving. cool, huh?
