The engine maker files this assembly under governor, while the trade sells it as a fuel pump — and that single word changes what a buyer checks before paying. This page gives the official description, the machines that carry it, and the six figures most often quoted in its place.
| Product Name | Governor group, unit injector fuel system |
|---|---|
| Official Description | GOVERNOR GP-UNIT INJECTOR, listed under the fuel system of the 3114 engine |
| Part Figure | 113-6187, written 1136187 without the dash |
| Parent Group | 113-6183, of which this governor is one item |
| Engine | 3114 four cylinder, four point four litre, 105 by 127 mm, mechanically actuated unit injectors |
| Machine Fitment | 924F wheel loader and IT24F integrated toolcarrier, and other frames using the same engine rating |
| Function | Sets fuel delivery against engine speed and load, and carries the shutoff and the rack linkage |
| Drive | Gear driven from the front train, flange mounted |
| Condition Offered | New, and rebuilt with a bench report |
| Packing | Port caps fitted, rack linkage braced, foam blocked carton |
| Two Cylinders Fewer | The six cylinder relatives of this engine share its bore and stroke, and their governor groups are sold under different figures that do not fit a four cylinder block. |
|---|---|
| Figures Quoted In Its Place | 4P-4306, 130-7323, 105-3576, 6I-4267, 4R-9036 and 141-1238 are all six cylinder assemblies, and a buyer who quotes any of them is describing a different engine. |
| Governor Versus Pump | The assembly governs delivery rather than generating pressure, because the pressure is made at each unit injector, so a bench test of rail pressure is not the right check. |
| Calibration Follows Rating | The same casting is set for different horsepower ratings, and a governor set for a loader will not fuel a generator correctly. |
| Serial Break | The figure applies from a stated engine serial upward, and earlier engines carry a different governor. |
Related Components: Unit injectors, priming pump, filter base, shutoff solenoid, rack linkage, drive gear.
