I am going to look at a 1850 diesel that is for sale about 4 hours from me and I would like to know what things to look for that would be indicators something major is wrong with the tractor. I have no experience with diesel tractors or Olivers. All my experiences has been with JD two cylinders. I know the obvious things to look for like oil color, or oil leaks, or strange sounds, etc. , but would be unique to an oliver 1850 and to a diesel engine that I should look for?

For those interested, you can see the tractor if you search TRACTORHOUSE.COM OLIVER 1850. the tractor is at Lori-Lin Farms in PA.
 
If I was looking at a tractor to buy I sure wouldn't advertise where it's at.
I owned an 1850 years ago. It was a great tractor. Traded it on a Case 2290. Don't know of any weak points except maybe the over/under and I'm not even sure if it is a weak point. Mine never acted up. Sorry, not much help. Good luck.
 
If they used ether to get it started then I'd suspect the pistons and/or piston rings are broke. Don't ask how I know.....
 
Make sure the HydraPower Drive or Over-Under Shift work it it is equipped with one (expensive fix), and make sure you don't have to constantly turn the steering wheel to keep going in a straight line (no fix). If you are going to need the PTO make them hook it to a dyno and check it.
 
How I check is put tractor in 4th gear, apply enough brake to make the engine lug a little and shift. Up shift will be crisper than down shift but you will feel slippage or slow engagement. I also pull the dipstick and feel and smell the fluid.
 
The 3 speed over-under in my 2-105 has had a seal replaced, and oil and filter changes since it was new in Feb 1975, no idea of hours, gotta be tough, been shifted a billion times and still works good.
Those 3 speeds are tough if respected a little.
