Case 680E

[Eugen]

Sludge be gone! Cleaned up the oil pan. There was no need to wire wheel more than the perimeter but I just couldn't stop myself.

Dang! That’s so clean it’s almost a shame to put oil in it!
You said that torque adapter shows a max of 220 and you had it set to 210. Do you feel it was giving an accurate reading of the force you were applying or is it off a little?

[Eugen]

I don't know Jeff, it's supposed to be up to 2% accurate. I'm thinking the sensor records the peak torque it sees and maybe the bolt doesn't tighten in small torque increments. In any case, I'm not worried. The service manual has a torque chart and it says 200 - 240 ft lbs for grade 8, size 5/8 bolts. Even if it went a little over 210 I think it's fine.

Had some more time today so I cleaned and installed the push rods and rockers

With the oil pan so clean I thought I'd try to install it. @JSinMO , indeed I have no plans of getting that oil pan dirty.

If you remember this operation needs the nose (radiator enclosure) and the engine lifted up front. Used the 644 loader again to lift the nose and then the 12 ton jack to lift the engine.

But when I looked more carefully I realized that the oil pump pipe was not routed correctly and the pan wouldn't fit. This is because it got bent/ straightened when I too the balancer off. Oh well, it's 1/4 inch OD steel pipe but quite malleable so after taking it off again, I bent it to route it in such way that it would not interfere with rotating crankshaft or the gears. Here's a picture of the correct routing in case some poor soul makes the same mistake as I.

Now the pan needs to get ready: a bead of permatex black to stick the gasket on the pan.

And a bead on the gasket before sliding it under the engine above that cross member. Had to lift the front of the engine quite a bit and it was still a tight space to wiggle the pan in. But it worked, and the oil pan bolts got screwed in and torqued.

Was a long day but the progress is satisfying.

Eugen you have come a long way on the progress of this project. Meticulously cleaning, checking, torquing and assembling everything. I’m sure you will be smiling from ear to to ear when you crank this engine and it starts. Especially when you get to use it and move some dirt. A feeling of satisfaction and accomplishment like no other. Congratulations and thanks for documenting and posting all the details. Harry

Ouch

Hopefully I torqued the rods right.

Still a ways to turning it on though. Adjust valves, reassembly of injectors, all injection fuel lines, hoses, radiator, engine mount, nose. Then the manual calls for one hour running under load and then retorque head bolts and rockers nuts while engine is hot.

Meanwhile nobody wants the Johnny bucket project tractor so I'm thinking of fixing it

I see a big hole in the block. Is this on the 680E? Harry

No, just me joking around. Hopefully this won't happen to me.

[Eugen]

I won't bore you with the details, but today I tried to deal with all those little things I mentioned in my previous post. Around 5:30 it was time to look for the key. After some fuel priming... it started. Here's the second start.

More work is awaiting, but now a full hour of working it under load is needed. Not today.

WooHoo!
Looking Good @Eugen
