I was going to say that.........Just like Ikea
I don't know about Komatsu boxes John, but the 789 and 793 boxes I've worked with came in 4 pieces, centre section, LH & RH side sections, & headboard. The wear plate packs came separately. The welders worked 2 x 12 hours shifts to nail them together.The biggest issue I saw with them was the boxes come in two halves that have to be welded together. The number of days it takes depends on the amount of over time is allowed. Most crews work half days. One crew works 12 hours and then the next crew comes in and works the other twelve hours.
No in-frames, no mid-life injectors & turbos, even the overheads only get run every 4000 hours. End of life, snatch the whole engine/radiator/generator power pack in a single lump. On earlier Komatsus the complete power pack rolled out of the front of the frame on rails, never been around a 980 so couldn't comment.I wanna see someone do an inframe on that engine. The rear section seems a bit tight to the frame all around.
