I found a 7045 nearby for sale. It has about 4500 on the tach, but it doesn't work. It was bought from a farm auction a year ago. Has been used for a year by present owner and leased out to run a grain vac. All say it runs fine. There is plenty of old oil and dirt on the engine around the valve cover and the interior is well worn with foam gone. The tin is in pretty good shape. They are asking $8,000. I would really like to have it, but am afraid of not knowing the history or actual hours. It's a power director, clamp on duals, no front weights. Any thoughts? What have been other's experience with the 7045? Was it a solid performer? Did the 7045s have the same issues as the 7080 and 7060 breaking cranks? Thanks for the help.......

7060 didnt break cranks 7080 broke the nose because of the hardning process in the counter balanced cranks, not a hp issue either because the nose snapped off, not the middle or back of the crank. 7045 were a great tractor but if the condition is a little rough 8000 would seem high. Cab kits are goig to run you 3-400 with the floor, valve cover gasket & the kit to keep it tight is cheap enough, if thats all thats wrong. If you have to get into it mechanically thet runs into money quickly.

The 7045 is a great tractor with some refinements over the 7040. If I am not mistaken, the entire tracotr is basically a 7060, with a detuned motor, and not intercooled. They are workhorses. My grandfather had one, for a while before he passed away, and it was just as solid as the rest of our big 7000 series tractors, now my cousin runs it, and as far as I know it is still solid.
I too tend to think 8K is on the high side, but that may be a dealer thinking it is gold. I would think 6K to 7K should buy a good straight lightly faided power shift 7045 with say 50% of the rubber left. These are mid Nebraska numbers, I would think that MO would be less yet, as there are tons of Allis in that area. Now if it has all new or nearly new rubber on the back, then 8K is probably fair, as a new 20.8x38 will run up against a grand if not over depending on brand.

A sharp good rubber nice paint cab etc should be in the teens 13-16,000 would be a good price, but if they are rough, and didnt look like they came from the best care 8000 is high. I dont want to leave the impression that a 7000 series is a cheap tractor, and be bought for peanuts when in great shape. Condition is everything, and at 8,000 by the time you cherry it out your going to be over the 15,000 mark and now it gets tough.Unless you are planning on keeping it than its a toss up, just remember if you open that motor up to do it correctly your going to spend 5-9 grand.

If I remember correctly, the 7045's had a two pinion differential, vs the 7060's four pinion. Also, I believe the axles are a smaller diameter on the 45, but don't quote me on that.

I am pretty sure Orangeblood is right about the makeup of a 7045, I know the axles are the same as a 7060 because I have switched mounted duals back on forth on mine. I think 8k sounds high from what you described. I bought mine and had to put a bunch of money in it, but it is a really good tractor now and serves its purpose well.

the 7045 is probably the best 7000 series made, very reliable.

All 7000 series allis Chalmers tractors had 3.75 Dia. rear axles with two exceptions. The 7080 had 4.00, and the 7000 had 3.25. The 7045 is a very nice tractor for small to medium size farming operation.

Thanks for the comments and advice. I have a real nice 7010 original with 8000 hours on it. If the 7045 were as nice as it was I would buy it in a heart beat. Just too scared of getting a high houred machine with no history. I want it for a working tractor. I was thinking a new cab kit and good wax job would be about all I would want to put in it. Maybe paint the frame and wheels, but I would like to use it. Maybe I can still talk myself in to it!
