Happy Birthday
@Eugen Have a special day on your birthday! Buy your wife and kids presents.
They will appreciate you. Have a Good day!

I personally don't drink but this could be a frosty mug of A&W Root Beer.

Happy Birthday, glad all are well now! Spending time with family is a great way to celebrate

Like others have said just keep an eye on things and troubleshoot as you go.

And yes, bigger tractors can be scary to little ones - I remember one of my brothers crying when my grandpa would start his IH 986. He'll be watching you in it soon enough and then wanting to be up there too

I didn't want to get excited but ran the tractor for about 10 minutes, moved it back and forth, lifted the bucket and backhoe. Engine oil level doubled. Now I'm trying to figure out if it's hydraulic fluid or diesel that makes it into the engine. And all of a sudden I now know why the guy let it go so cheap.

I'm thinking that the only way for hydraulic fluid to make it into the engine would be from the pump. The pump is located a the front of the engine, has a splined shaft that gets turned by the engine. Trying to make sense of how this could happen. If the shaft seal on the pump is damaged, then fluid would go in via the crankshaft seal which also must be damaged.

Looking at the parts manual, the pump shaft turns that hub, which I think is connected to the crankshaft pulley. If this is where the leak is, I'm actually surprised that it's not an exterior leak. got myself into a tight spot I think.

Actually the hub seems to have 8 holes and the crankshaft pulley only 6, so that's not where the pump is connected.

I’m sorta remembering a bit now about the Ford I mentioned earlier. The power steering pump was run by the crank or cam by a gear or chain. Any way, power steering pump had a bad shaft seal. So the steering fluid would run out the seal to where the pump was driven by the gear or chain which was the engine oil side.

Sorry to hear of your troubles Eugen.

Can’t see how it would leak from the pump seal into the crank shaft seal. So was the hydraulic oil down, after doing this 10 minute run. ? I know nothing about these tractors or engines. But would there be a diesel fuel line in the engine leaking. Or the fuel injection pump leaking into the engine some how.

Chev Duramax diesel trucks had that problem. Diesel line in the engine would fail and fill the base oil with fuel.

Might be time to get excited. Don’t run it to much if it’s diesel fuel in the oil. Might harm engine.

Can you take some pic. of the hydraulic pump and the injector pump so I can get batter idea of what you got .

Be easier to see stuff, that’s for sure. Maybe power steering pump too if there’s one.

Noel

I'll get some pictures of the actual thingy there asap.

But just figured this out: the 6 hole crankshaft pulley picture was from the service manual, but in the parts manual it shows it pretty clearly with 8 holes.

OK, I think I got the right picture in my head now. The crankshaft comes out of the engine and it has a seal. The crankshaft pulley bolts on the crankshaft. There is the pump to engine bracket around the pulley. And the hydraulic pump is mounted on the bracket, but its splined shaft mates with the splined hub, which is bolted on the crankshaft pulley with 8 bolts. I find it hard to believe that hydraulic fluid makes its way out of the hydraulic pump, through the crankshaft seal and into the engine.

Can’t happen as far as I know. Crank or pump seals bad it would be running out on the ground.
