Oliver 70 value?

Looked at a Oliver 70 gas today, sheet metal and grill are very straight it has been painted at some point years ago, the side curtains are missing but otherwise complete, no hydraulics or belt pulley, does have rear pto. Rear tires are pretty good and not flat, fronts are flat but tires look good. Was inside a shed but now sitting outside. He said it ran when he parked it in the shed, but we've all heard that many times. The engine is stuck. He said make an offer. I have an idea on a price range but wanting to see what everyone else thinks on a fair price. Thanks
 
A tractor that does not get a whole lot of respect yet many were sold new back in the day. Being stuck I would say no more than 500 dollars and it would be a shame if it went for scrap. Guys like Randy Lund will be along to voice their expert opinions.
 
Stuck makes it at best a gamble. If stuck from sitting $300-500. If stuck due to rain getting in the engine less. So is there water in the oil and or the oil over full?
 
While reading your post, $400 was the figure that came to my mind. Seems to be right in the range of the others too.
 
I don't think there's water in the oil. And it has been inside until about a month ago and it does have a rain cap on the exhaust so that's a good thing. I've restored many that were stuck so I know all to well the problems that can be found upon teardown.
 
Most I have gotten that where like that as long as there was no water in the cylinders a simple ATF treatment freed them up and where easy to get running again
 
40 Inch rear tires are very expensive to replace compared to 38 inch tires. Check what they sell for in running condition, that is often less than $1000. Engine stuck, side panels missing could make it a project you don't want to begin. You might be able to find a 77 in similar condition with live PTO and live hydraulic for about the same money ($400).
 
It has a obsolete Continental engine. If it needs any serious engine work you need a good machine shop that can think outside the box and use various parts from other engines to get going. One place in Oregon I believe had some bearings. And I think wrist pins are available. A running painted one is usually about 1200 dollars.
 


Maibahh Tractor in Creston Ohio is a good source for parts. I bought one with complete sheet metal running 12 years ago for $600. I got a sleeve kit on Ebay for short money and rebuilt the motor.
 
A finely-tuned Oliver 70 running is music to the ears. It doesn't matter what brand you enjoy, everyone admires the smoothness of that six cylinder engine.
Now, the not-so-good points. You could easily put $2K into the engine and have trouble getting somebody to pay $1K for the whole tractor, even with good tires. It's the one Oliver model that just doesn't bring much money. About a year ago, I got one on an estate sale for $750 and I drove it home. Nobody really wanted it. Engine parts are getting very scarce. As little as six months ago, there were lots of replacement pistons advertised for it on ebay, if you knew what number to look for. Not any more. Engine bearings are scarce. Several years ago, I got a bunch of them from RockAuto, believe it or not. I knew the bearing number and purchased them by number, not application. I'm not sure if new sleeves are available from anybody. If so, I'm sure very pricey.
Getting back to the subject of the original post, I'd probably try to purchase it for $400, tops. You might get the engine to turn over and run good or you might not.
 
Thanks for the info. I agree the 6 cyl has a great sound. Someone else had also said it was a continental engine and that parts are scarce, I thought Oliver used mostly waukesha engines but I know this is an earlier model too and I don't know much about Oliver. I think I'll pass on buying it unless he offers it cheap. Thanks again
 
That's a hard question to answer. It might be lightly stuck and not cost much to get it running, or, it could take a complete overhaul. Maibach is an excellent place for parts. Two years ago I bought a piston and sleeve kit, $1000, gasket kit, some valves and a few other parts. Parts for this engine are very expensive. I have more in this tractor that what it's worth. But I'm glad I did it. If this one has 40" rears, that's another thing to consider. Will they last for a long time yet, If not, the only ones available that I know of are 9x40s. Mine has 38s. It all depends on how much you want a 70 and what you are willing to put into it. At $500 I would go for it.
