My son was given a 2520 that belonged to his grandfather,the tractor had antifreeze in the oil and was sold to a friend who is a collecter.The tractor was completly overhauled and repainted 10-12 years ago and was ran less than 10 hours,it has not been started in 5-6 years.(Dad was killed in a farm accident 13 years ago and this friend just gave the tractor to my son)He went to pick it up today and the engine oil was thick and looked terrible,they cracked the oil pan drain and got water(tractor has anti-freeze in it) we are figuring that it is condensation.He decided to pull the oil pan to clean it up before even trying to start it and while it was off he pulled a main bearing cap and found rust on the crank where the oil groove in the bearing is.Took the fuel cap off and the inside of the fuel tank is rusty.He drained all the fuel and is planning on flushing the tank and adding clean fuel.Also found a small rust trail down the outside of the block coming from the head.Should we even try starting the tractor or should we haul it home and tear the engine down first? Right now the tractor is several 100 miles from home.The tractor has been setting in a large enclosed metal machine shed.The said part is that there a 20 other tractors in the same shed and probaly in the same condition.I know who did the engine work and feel it was done right.Should we pull the bearings one at a time and emory cloth the crank? The bearing show no rust only in the oil groove on the crank.He pulled the oil pump to clean it up as well.Another question is should we add break in oil to it as it has ran less than 10 hours since overhaul? Any thought and ideas on what to do? My son is very disappointed has he has known that when he turned 18 he was getting this tractor but now it has all these problems from sitting. The tractor is in a somewhat warm climate so I think the antifreeze probaly has protected the block from cracking and when he drained the oil no antifeeze only water came out.Thanks Tom
