Isuzu
Model Number:
8-97603414-4
| Product Name | High pressure common rail fuel pump, HP0 family |
|---|---|
| Component Figure | 094000-0484, also written 0940000484 |
| Engine Figure | 8-97603414-4, written 8976034144 without dashes |
| Matching Rebuilt Pair | The -0 engine figure and the -0480 component figure travel together |
| Same Block Neighbours | 094000-0481, 094000-0483, 094000-0485 — each a separate calibration |
| Engine | 6WG1, 15.7 litre six-cylinder, turbocharged and charge-cooled |
| Machines | ZX450-3, ZX470-3, ZX470H-3, ZX500LC-3, ZX650-3 and their near neighbours |
| Control | Suction control valve on the inlet side, rail pressure closed loop |
| Drive | Gear train, flange mounted with a keyed coupling |
| Supplied With | Inlet fitting, outlet union and mounting hardware |
| Condition Offered | New, and tested rebuilt with a bench pressure report |
| Packing | Ports sealed, shaft protected, foam-blocked crate |
| Two Systems, One Badge | Earlier builds of this machine ran an in-line mechanical pump driven from the camshaft, while later builds run the common rail unit shown here — the two share no flange, no coupling and no pipework. |
|---|---|
| The Mechanical Numbers Still Circulate | Second-hand listings and workshop notes quote the older in-line figures against the same model name, which is the single largest cause of a wrong pump arriving on site. |
| Pairing Rule | Component figures ending -0480 and -0484 are distinct calibrations, and each travels with a different engine figure ending -0 or -4, so both sides must be read from the same plate. |
| Four Calibrations In A Row | -0481, -0483 and -0485 sit beside this number and are quoted loosely by resellers who treat the block as interchangeable. |
| Cheap Lookalike | A feed pump bearing a similar eight-figure number is sold for a fraction of the price and is often titled as a high-pressure pump in bulk uploads. |
| Another Rail Family | A later common rail pump from the same engine also exists under a 294- prefix, and it belongs to a different hydraulic layout. |
| Displacement Split | The 14-litre relative of this engine appears in the same listings, and its pump will not satisfy the larger block. |
| Caution — Metal Downstream | When a pump wears, the rail, the pipes and every injector receive the debris; a replacement fitted without a full flush fails within weeks. |
| Caution — Suction Valve | The inlet metering valve is matched to the calibration; a pump supplied without its correct valve will idle badly and set a rail pressure code. |
| Caution — Leak Off Test | Excess return flow from the injectors is frequently mistaken for a pump failure, so the leak-off test belongs before the order, not after. |
| Caution — Clean Bench | The outlet union is a sealing face on the high-pressure side; a single grain of grit under it will weep for the life of the pump. |
| Related Components | Common rail, injectors, rail pressure sensor, feed pump, filter assembly, high-pressure pipes. |
The pump body plate decides, because the model name is shared by both builds.
No — they are separate calibrations and each belongs to its own engine figure.
It is a feed pump, not the high-pressure unit.
Filters, and a full flush of rail, pipes and tank.
No coding is written into the pump itself; the valve must simply be the correct one.
Injector leak-off exceeding spec, which is measured before the pump is blamed.
