We call that Bunker oil here. Used in maritime for a time, then in heavy boilers, finally used to thin slabs of solid asphalt for paving roads!!

Never seize seems to jump from one part to another so that you can enjoy it more.
Did some work over the years and found Carbon Black not much fun either. Starts as white powder, turns brown just before it turns black and is about permanent bonded to your skin. Goes through your clothes, like a fart in reverse. You throw away all your clothes and I have seen guys throw away tools that were covered with Carbon Black.

They will wear slots in the pads over time. The cogs wheels will have the wear marks of the lugs on the cog wheels as well. I've seen that system on big cranes also and never thought about the track chains probably wouldn't take the weight anyway.
Here's a view of the drive tumbler showing how it engages the track pads. You can also see how the centre end of the track shoe pin bore is a reduced diameter to stop the pins walking inwards while the bolt on the outside stops them walking outwards.

Without actual rails the system has a better chance to clear itself of packable debris, another plus.

While the welding of the travel motor guard bases was going on it was a good time to start assembling the platforms, walkway, & handrails for the LH & RH modules. And before anyone says anything...... yes I know those handrails are bent. Result of some d1ckhead in the port trying to lift a pallet using a crane instead of a forklift. It would've been relatively fine had they slung it from the pallet, but they fixed the slings to the handrails and when the strapping broke it dropped the whole shooting match about 10ft to the ground. New ones are all available in Miami and are on the way already by air-freight. Should be on site by the middle of the week, fingers crossed.

Dock Hands were a bunch of Rubes if ask me, who signed off their longshoreman tickets as that is just beyond stupid as to damage incurred.

And now for what the Scots call "The Big Yin". All of a sardine it's starting to look like a digger.
Damn thing fought us all the way though. Sometimes the four swing pinions just slide into the ring gear, sometimes they don't. We spent 2 hours fighting it until the pinions finally meshed and it slid into place. Then there is a small matter of having to swing it 180 degrees and back again, because only about 6 bolts front and rear will actually install, there isn't enough clearance to get them in above the carbody. So after tightening the first dozen bolts we used a forklift truck to slowly swing the upper frame in order to get all the others in, then swung it back again. Today is Hytorc day to fully tighten all 60 bolts to 7,250 ft.lbs.

This photo was taken at the docks. The whole shooting match came half-way round the world, was trans-shipped twice during that time, and arrived without so much as a scratch. Then this happened........

Is that machine running two separate engines and sets of pumps? I did an appraisal on a big Hitachi years back that was configured that way.

Appears as they left notable room for working on this.
It gets even better. Apart from regular maintenance the best thing to do is to have a complete "power pack" (engine, radiator, hydraulic oil coolers, pump drive, pumps, etc) all assembled in the module which is the grey & orange box you see here, then swap the whole thing out as one unit. With a bit of planning it can be done in just over a day. It's not that heavy, comes in a shade under 30 tonnes.
