Bosch / Zexel Fuel Injection Pump Assembly F01G00506C 073Z095775 6P120/721LS3000
Key Technical Specifications and Design Details
1. Inline 6-Cylinder Plunger Design: Features six independent plunger assemblies mounted side-by-side within the pump and driven by an integrated camshaft at the base; these correspond to engine cylinders 1 through 6.
2. 12mm Plunger Diameter: A specification designed for large-displacement, high-injection-volume applications, capable of delivering a very high fuel quantity per injection cycle to heavy-duty diesel engines.
3. High Mechanical Pressure Capability: An upgraded version of the mechanical P-type pump, featuring a reinforced, thickened pump housing designed to withstand instantaneous injection pressures of 800–1200 bar at the plunger end, ensuring thorough diesel atomization.
4. Integrated Mechanical/Electronic Governor: A governor assembly is integrated into the rear of the pump housing; certain batches support external electronic governor actuators to precisely maintain engine speed under complex load fluctuations.
5. Forced-Circulation Lubrication: The pump connects directly to the diesel engine's main oil gallery via inlet and outlet ports at the base, utilizing engine oil for forced-circulation lubrication and heat dissipation, thereby extending the service life of the camshaft and bearings.
Core Engine Compatibility
Isuzu 6HK1 diesel engine (compatible with Isuzu official part numbers such as 1-15603-334-5).
Selected classic 6-cylinder heavy-duty engine platforms from Mitsubishi and Hino.

| Item No. | Part Number / Category | Description (EN) | Qty | Material Property & Replacement Advice |
|---|---|---|---|---|
| [Part A] | External Installation Accessories | (Mandatory for Engine Installation) | ||
| 01 | F01G00506C | Fuel Injection Pump Assembly | 1 Pc | Core Assembly: Replace entirely if the old pump casing or internal drive is badly damaged. |
| 02 | 1-15419-242-0 (Ref) | Front Mounting Flange O-Ring | 1 Pc | Mandatory Renewal: Prevents engine oil leaks at the joint between the pump and the engine timing gear housing. |
| 03 | Standard M14 / M16 | Fuel Line Copper Washers / Gaskets | 12 Pcs | Mandatory Renewal: For banjo bolts and return lines. Reusing old washers highly risks diesel leakage. |
| 04 | 6HK1-ICT (Ref) | High-Pressure Fuel Injection Pipe Set (Cyl 1-6) | 1 Set | Inspect & Replace: Renew if pipe ends are deformed, or if internal metal debris/carbon fouling is detected. |
| 05 | N/A | Fuel Filter Elements (Primary + Secondary) | 1 Set | Highly Recommended: New filters must be installed before priming the new pump to prevent premature plunger seizure. |
| [Part B] | Internal Pump Overhaul Components | (For Bench Testing & Calibration) | ||
| 06 | 1 418 412 xxx (Ref) | 12mm Plunger and Barrel Element (P-Type) | 6 Sets | Core Wear Part: Replace if symptoms like black smoke, loss of power, or hard starting when engine is hot occur. |
| 07 | 1 418 522 xxx (Ref) | Delivery Valve Assembly | 6 Sets | Core Wear Part: Replace along with plungers to ensure crisp fuel cutoff and prevent nozzle dripping. |
| 08 | F01G Gasket Series | Full Pump Overhaul Gasket & Oil Seal Kit | 1 Set | Mandatory Renewal: Contains side cover gaskets, governor seals, and front/rear driveshaft oil seals. |
| 09 | Roller / Camshaft | Drive Roller Tappets / Camshaft | A.R. | Inspect & Replace: Renew if pitting, flaking, or heavy scoring is found on the cam lobes during disassembly. |
