Fancy cutting saw I unloaded at a machine shop monday. Was supposed to be 12,000lbs. They were planning on using a pallet jack and a forklift to put it in place in the building. I had my old 25 ton grove (its about the only thing I have running right now:rolleyes:), good thing I had it instead of the mack/ national, it was 21,500lbs.

I set it down and told them they were going to have to rethink the whole pallet jack plan. They had asked me to bring my machinery skates, so we put them under one end, and two pallet jacks on the other end, and pushed and pulled with the forklift to get it in the building. 20200210_101646.jpg

Also got my block stowage rack built for the 40 ton. I've been going round and round with the parts guys for the bad pressure transducer to make the LMI work. I think I've got the right parts on the way now for it.

New pac brake showed up for it today also, the old one was rusted tight, I got it freed up, but the cylinder was bad as well as the spring, so I just bit the bullet and got a new one. Actually, I think this one is military surplus, it was $550 off ebay, new ones are more like $1500. The new one is the "improved" model. My old one didn't have the extra arm and spring, I think its to control so it doesn't do too much back pressure.

I think this is where my problem is in the 100 ton. The wiring is 20 years old, and it has a black outer cover that is super hard, it cracks instead of bends. This area with the blue wire coating gone, had a break in the black cover and it could have been touching on the block or the injection pump. I peeled back all the black part, and I'm going to splice in a section, if I can figure out where it goes to in the lower cab, its getting a whole new wire.

There are a lot of small hairline cracks in the insulation of the wiring. I hate the thought of replacing a wire at a time, but a new harness is big $. I think I may just end up going that route, it may save time in the end.

Its so hard and brittle, it seems like the more you touch it and mess with it, the worse it is. I'm sure we didn't do it any favors when we unplugged it all and laid it out of the way when we swapped engines.

Looks as should have back wound the sensors another four to five turns, WOW!! I see they can plug in.

Wiring in a high heat load area CO? brittling the insulation?

I think its a combination of heat and age, as well as the type of insulation. It really only had a small crack and area exposed. By the time I got it unwound, and the black outer layer off, I had a lot more insulation falling off.
The outer black shield is like a heat shrink, its hard to remove and very brittle, I got it off with a combination of razor knife and bending it to where it would crack. There are numerous other small spots in other wires with cracks in the insulation, which makes me think pretty hard about a new harness.

When they have three wires going to a sensor, its like they were machine wound together, then a heat shrink outer over them. I've got wiring in 40 year old stuff with wiring in better shape.

Pretty common on High density heavily obstructed air flow machines as these. Some of the harness sheathing I have seen last thirty years brittles out pretty easily quickly and badly.

Typically when wire is wound like that it’s data transmission and not analog/digital signals. Some form of canbus. It’s to prevent outside frequencies from interfering with the data transfer.

The machine is canbus (at least that's what the tech says), the mass air flow sensor I'm dealing with right now is 5 volts DC , then the blue wire is signal to the ecm.

Try scoring the outer jacket with a razor knife and then hit it with a heat gun. If it is heat shrink, it will split along the score line and you should be able to pull the covering right off. Cam

CANBUS/signal/data transmission wires such as the one in your photos should have approximately one twist per inch of length to prevent outside interference with the signal that is being transmitted along the twisted wires.

First job with the 40 ton. I got the pacbrake installed, but its got something up with the wiring, so its installed but doesn't work. Went to stand a tank monday, it runs well, the C7 engine really surprised me. I hate to admit it, but the allison is pretty nice also. Need to get the pacbrake working though, or we're going to eat those new brake shoes right up, takes a lot of brake to slow it down.

Its got a pretty good engine oil leak, coming from behind a bracket on the top rear of the motor. It looks suspiciously like the rear of the head gasket, but I'm going to have to pull some things apart just to see where its coming from. LMI isn't working properly yet either. I've got a new pressure transducer to put in, and I think the boom length is messed up also.

But at least its out and running. Of course a maiden voyage wouldn't be complete without troubles, fortunately it was only a flat tire. I made it to the job and finished it, then went to the tire shop before driving home.

Old concrete plant tear down. The portland silo had a extra 10,000lbs of old material still in it. The worst one was the fly ash silo. I got attached to it, and it didn't even want to move.

"oh- it still has some in it- maybe 20 ton or so"....

Well I was the bearer of bad news, and they ended up in the air nozzle holes with rebar trying to get it to run out. I pulled it off the leg stand, at 42,000lbs. I knew there was no way it weighed that much, so I made them go back to work getting more material out. It ended up only weighing around 12,000lbs by the time we got all the fly ash out. Its a wonder that we didn't rip the roof or the picking eyes off the tank.

What a dusty mess. The wind was somewhat favorable, but I still have it all over the crane. We blew as much of it as we could off with a air nozzle, and I swapped air filters too.

Had to load the base of the wet well. Flatbed tandem is great for this kind of stuff. They carried the risers down the hill with excavator, but they couldn't pick up the base. Took the 40 ton out there to load base, about 22,000lbs.

How many golf courses are there in Branson now? And are they all cut out of solid rock?
