This 91-page Isuzu 4JJ1XZSB03 Parts Catalog (OEM #P-TB1160W_EEOA) exists for one purpose: identify every engine component and order the correct replacement part on the first attempt. Exploded-view diagrams break down cylinder head assemblies, crankshaft components, and fuel injection systems, while full part numbers cover gaskets, bearings, sensors, and seals. The catalog includes 38 pages of engine parts breakdowns spanning piston rings to turbocharger adapters, plus complete parts lists for the oil cooler assembly, water pump mounting hardware, and exhaust manifold heat protectors. Look up part number 15-87817-0650 for the cylinder head gasket (1.05 mm thickness) or locate the exact fuel injection nozzle (part 18-98201-5640) without guessing. No more wrong seals because you eyeballed it. Opens on any device; search by part number or component name and get back to your rebuild.

Isuzu 4JJ1XZSB03 Common Problems This Manual Covers
Isuzu 4JJ1XZSB03 turbocharger assembly part number needed after oil contamination and seal failure p. 50
Refer to the turbocharger system exploded view on page 50. The complete turbocharger assembly is part #18-98134-2272. Confirm the gasket set (part #18-94433-6050) is included for proper sealing. Cross-reference your engine serial number with the parts index to verify compatibility before ordering.
Manual Section: Turbocharger SystemCannot identify correct fuel injector nozzle part number after misfiring and black smoke diagnosis p. 52
Turn to the fuel injection system parts list on page 52. Individual injector nozzles are cataloged with specific part numbers based on engine configuration. Measure the nozzle holder outer diameter (typically 17-19 mm range) and match it to the illustrated components. Order the complete nozzle assembly rather than individual seals to maintain proper fuel spray pattern.
Manual Section: Fuel Injection SystemNeed sensor part numbers after water damage caused corrosion and no-start condition p. 68
Open the engine electrical control parts section on page 68. Common sensors include the rail pressure sensor, temperature sensors, and throttle position sensor, each with distinct part numbers. Match corroded sensors by their connector type and mounting location in the exploded diagrams. Replace sensors as complete 24V-rated assemblies to avoid intermittent electrical faults.
Manual Section: Engine Electrical Control PartsCylinder head gasket kit part number unclear during engine overhaul after head failure p. 11
Review page 11 for the engine gasket kit parts number list. The complete head gasket set includes the 1.05 mm thickness head gasket plus valve cover gaskets and seals. Confirm the M11X114 cylinder head bolts (page 17) are replaced during reassembly. Match your engine serial number prefix to verify correct gasket compression specifications.
Manual Section: Engine Gasket KitOil cooler assembly part identification needed after finding metal contamination in oil system p. 58
Navigate to page 58 for the oil cooler and oil filter exploded view. The oil cooler assembly includes mounting gaskets and plugs as separate line items. Inspect the oil filter mounting base (separate part number) for cracks or thread damage. Order the complete cooler assembly if internal passages show scoring beyond 0.5 mm depth.
Manual Section: Oil Cooler and Oil FilterWiring harness part number required after electrical short damaged multiple connector pins p. 76
Consult the wiring harness section on page 76. The engine harness is listed as a complete assembly with fixing clips (12 mm ID band clips on page 79). Identify damaged sections by connector color codes in the parts diagrams. Replace the entire harness rather than splicing individual wires to maintain proper wire gauge and insulation resistance specifications.
