Part of the Case Repair Manuals.
All 206 pages of this Case F4 Series Engine Repair Manual (OEM #87630273 NA) target one job: rebuilding the F4GE9454H, F4GE9454J, F4GE9484D, F4HE9484A, and F4HE9484C engines in Case backhoe loaders. Inside: page after page of exploded component views covering crankshaft, piston, and valve assembly, plus wiring diagrams and connector pinouts for the complete EDC7UC31 electrical system. You also get a full troubleshooting section covering conditions from no-start to runaway, torque tables split by engine family, and fuel pressure test values for both mechanical and Common Rail injection systems. Torque your F4GE injectors to 55-65 Nm; on the F4HE, bring the M6 injector bolts to 8.15-8.85 Nm before the 75-degree final rotation. Your engine is apart and the right spec isn't on a forum. Bookmarked by section so you search any value, pull it up on your phone, and get back to work.

Case F4GE/F4HE series Common Problems This Manual Covers
Case F4GE9454H backhoe loader engine coolant temperature runs hot within thirty minutes of operation. p. 10
Inspect the cooling system components. Check the water pump for leaks or a bad bearing as noted on page 10, and overhaul or replace if necessary. Verify the thermostat start of opening temperature is between 79 and 83° C. Torque the fan pulley M10 bolts to 37 to 49 Nm.
Manual Section: Engine Overheating DiagnosticsMechanical injection engine cranks normally but fails to start or produce combustion after replacing the fuel filter. p. 72
Test the fuel supply system on page 72. Measure the mechanical fuel lift pump static pressure at 1800 rpm. If the pressure falls below the required 0.47 to 0.61 bar, replace the lift pump. Torque the fuel pump fastening bolts M8 to 20 to 28 Nm.
Manual Section: Fuel System Test (F4GE)Persistent ECU-020 error code with rough running and sudden loss of power under heavy load. p. 12
Examine the air intake and turbocharger system on page 12. Clean or replace the air filter element. Repair or replace the turbocharger unit if you find damaged compressor fins. Tighten the turbine to exhaust manifold M8 pins to 6 to 8 Nm during reassembly.
Manual Section: Engine Lacks Power / Erratic Running DiagnosticsElectronic injection engine runs rough with active ECU-050 injector circuit malfunction code and excessive exhaust smoke. p. 199
Measure the electro-injector coil impedance using a multimeter as shown on page 199. Replace the injector assembly if the reading is outside the 0.56 to 0.57 Ohms specification. Do not attempt repairs, as these units are not repairable. Torque the injector fastening M6 bolts to 8.15 to 8.85 Nm.
Manual Section: Electrical, Charging and Start-UpFrequently Asked Questions
What are the torque specs for the injectors and cylinder head on CASE F4GE9454H and F4GE9454J engines?
For F4GE engines, the cylinder head fastening bolts have multi-phase torque specifications: M12x1.75x70 bolts are tightened to 45 to 55 Nm (33.2 to 40.6 pound-feet), M12x1.75x140 bolts to 35 to 45 Nm (25.8 to 33.2 pound-feet), and M12x1.75x180 bolts to 65 to 75 Nm (47.9 to 55.3 pound-feet) in the first phase, followed by additional rotations of 90 degrees ± 5 degrees. Fuel injectors are tightened to 55 to 65 Nm (40.6 to 47.9 pound-feet).
What are the replacement specifications for Fuel injector set?
For F4HE engines, the replacement specifications for fuel injectors depend on the engine's power output. For engines above 152 kW (204 h.p.), CRIN 2 DLLA injectors are used, operating at a minimal pressure of 250 bar (3626 psi.) and a nominal pressure of 1600 bar (23206 psi.). For engines below 152 kW (204 h.p.), CRIN 2 DSLA injectors are used, with the same minimal pressure but a nominal pressure of 1450 bar (21030 psi.).
What are the replacement specifications for Fuel pump?
For F4GE engines, the mechanical fuel lift pump should have a static pressure of 0.47 to 0.61 bar (6.8 to 8.8 psi) at 1800 r/min (rpm). For F4HE engines, the high pressure pump unit cannot be overhauled and must be replaced if defective. If the low pressure pump's pressure is below 6 bar (87 psi) or above 9 bar (130 psi) at 1500 rpm, it should be replaced.
How do you fix case F4GE9454H backhoe loader engine coolant temperature runs hot within thirty minutes of operation?
Inspect the cooling system components. Check the water pump for leaks or a bad bearing as noted on page 10, and overhaul or replace if necessary. Verify the thermostat start of opening temperature is between 79 and 83° C. Torque the fan pulley M10 bolts to 37 to 49 Nm.
