I take it thats the crosshead puller and marine jet drive? Can you elaborate, what is a marine jet drive?

It's one of these;

The bit on the floor behind the job is the bit in the picture with the two hydraulic steering cylinders running alongside. The part we're working on is the housing for the main propellor bearings which live within. Together the sub-assembly is about 1.2 tonnes of cast, machined 316 stainless. When it's running, the bearings are fed with pressurised, constantly circulated and filtered oil. The main oil seal had failed creating something of a slick behind the boat.

You want to complain about the cost of Cat parts? How do you fancy dropping $18K for one seal?

Pictures being shared of excavator buckets close to piping in the gas compressor stations being shared are frowned upon. Ive spent the last few months working around major gas transmission piping. We are making capital improvements in areas with several different pipes besides the mains. Each valve has 3-6 lines running to them for multiple uses. Everything has 600-1500psi running through it depending on location in the station

JD 450B with 4 in 1 bucket...clam cylinders at rebuilder (one pin was STUCK, 16lb hammer driven by Thor with 175k rosebud and #3 cutting tip for heat to remove.). Now making new pins out of 1.5" W1 round stock, one hole left to drill, followed by heat treat at 1450F and a brine quench. Will reheat to draw temper in welding rod oven.

Yikes! have any pics? How did they manage to blow holes in the block?

Years ago i saw a guy do the same to a Deutz V12 engine in an old Ingersoll Rand LF-750 compactor. was not pretty.

#4 rod broke at the big end 3hrs after egr cooler replacement and had low oil pressure fault immediately afterwards. Cat tested and changed oil and filter but he didnt cut filter open before he released it. If he had there was a small chance it may have been savable maybe. This engine has been an assache of problems since new 3500 hrs 2 egr coolers 1st one at 300 hrs and had to pull the head on that one. 3 injectors a broken front cover and oil pan gasket.this is in an 836 k the old 836h that just went thru a full rebuild went 22,500 hrs with no major engine work and 2 tranny repairs one of which was a rebuild

thanks for the pic Walker. That is a mess for sure.
Our 836H had an in frame done at 7500 hours, had a piston come apart and the others were showing signs of the same fate.
Hell of a machine tho.
