Part of the New Holland Repair Manuals.
Before the head comes off tonight, you can have the New Holland F4GE and LM Turbo engine repair manual PDF open at the diagnostics table: 117 pages, OEM 604.13.694, covering eleven variants from the F4GE0404B through the LM1745 Turbo. Wiring diagrams for the starter motor and alternator circuits close out the book, and a diagnostics chapter traces the main engine operating anomalies back to their causes before anything gets pulled apart. Full disassembly through reassembly takes up the bulk of the pages, from crankcase and drive shaft down to injection pump timing and tappet adjustment. Pull the cylinder head screws to 50 ± 5 Nm on the first phase, and expect 1.2 bar of oil pressure at minimum speed with the oil at 100°C. Guessing at valve timing on a rebuilt long block gets expensive fast. Bookmarked and text searchable, this PDF rides along to whatever your engine is bolted into.
