Aftercooler through turbocharger, cylinder block through both CAV and Bosch Model A injection pumps: the Case 4-390, 4T-390, 4TA-390 Service Manual PDF, OEM number 7-91612, walks all 342 pages of those systems end to end on a rebuild of the 390 diesel family. Front and rear oil seal replacement, piston and rod removal, and two gear and three gear balancer work take up the largest block of the book, with procedures running through pulling, inspecting, and reinstalling each assembly. Injection pump timing gets its own treatment for both pump makes, so your fuel side matches what is actually bolted to the engine. Hold connecting rod journal taper to 0.013 mm maximum, and pull 3/8 inch Grade 5 fasteners to 420 to 504 pound-inches. Bookmarks and searchable text put you on the clearance or torque sequence you want in seconds.
