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.

New Holland F4GE0404B, F4GE0454C, F4GE0484G Common Problems This Manual Covers
New Holland F4GE0404B cranks but will not start after fuel filter change, no fuel at injectors
Crack an injector line and crank; dry fittings mean air in the circuit. Bleed from the filter forward and work the primer until fuel runs clear with no bubbles. Follow the fault chart starting on page 10. On this engine, pop test the injectors at 260 + 14 bar before condemning the pump.
Manual Section: Main Engine Operating Anomalies p. 10Engine overheats at full load, temperature gauge climbs and coolant pushes out of the expansion tank
Check coolant level cold and pressure test the system for external leaks before pulling parts. Drop the thermostat into heated water and watch for the start of opening at 81 ± 2 °C, the spec on page 30; replace it if it stays shut. Inspect the water pump for weep hole seepage and bearing play.
Manual Section: Cooling System p. 30Oil pressure light flickers at idle when hot, gauge reads low at operating temperature
Verify oil level and grade first, then tee a mechanical gauge into the gallery. At 100 °C oil temperature the regulating valve should hold 1.2 bar at minimum speed and 3.8 bar at maximum, per page 57. If pressure falls short, pull the oil pump, check it for wear, and clean the pickup screen.
Manual Section: Lubrication System p. 57Light blue exhaust smoke under load, oil level drops between service intervals
Measure blow-by before tearing anything down: the limit is 20 cm3 per liter at 0.83 bar pressure and 26.7 °C oil temperature, listed on page 57. High readings point to ring and liner wear, so measure the liners against the tables starting on page 74. If blow-by passes, inspect valve guides and stem seals instead.
Manual Section: Cylinder Cluster and Valve Gear Repair p. 74Loud tappet ticking from the rocker cover after cylinder head work, valve lash out of spec
Adjust valve lash cold to 0.25 ± 0.05 mm intake and 0.50 ± 0.05 mm exhaust, per page 105. If the head was off, confirm first phase torque on the M12 x 1.75 x 70 head screws at 50 Nm ± 5 Nm from page 104 before angle tightening, then recheck lash after the first heat cycle.
Manual Section: Engine Reassembly and Timing p. 105Frequently Asked Questions
What are the torque specifications for the New Holland F4GE0404B engine cylinder head bolts?
The cylinder head fastening screws are tightened in three phases. The first phase for M12x1.75x70 screws is 50 ± 5 Nm, for M12x1.75x140 screws is 40 ± 5 Nm, and for M12x1.75x180 screws is 70 ± 5 Nm. The second and third phases require a 90° turn. p. 37
