Part of the Case Repair Manuals.
Both the naturally aspirated 6-830 and the turbocharged 6T-830 diesel engines are covered here, in the 276 page Case 6-830, 6T-830 Service Manual PDF published under OEM number 8-28420. Cylinder head and valve train work runs through the front of the book, and the cylinder block section is the longest stretch in it: crankshaft, pistons, rods, sleeves, camshaft, bearings and seals, each teardown ending in reassembly specs. Turbocharger failure analysis sits with the turbo procedures, so a wheel that rubbed tells you why before you hang a new one. Electrical specifications and starting circuit troubleshooting close it out. Machining limit on the cylinder head is 1.00 mm and minimum head height is 115.75 mm, so you measure before you decide to reuse it; fuel filters go every 500 hours. Bookmarked and text searchable, and the pages print clean enough to live on the bench and get dirty.
