Part of the Isuzu 4JJ1 engine documentation.
This is the factory Isuzu parts catalog for the 4JJ1XZSB02, a turbocharged 4-cylinder common-rail diesel engine. Across 93 pages it breaks the engine down system by system with exploded diagrams and Isuzu part numbers, so you can identify and order the exact component you need.
Coverage runs from the engine gasket kit and cylinder head through the cylinder block, camshaft and valve train, turbocharger, fuel injection, cooling, and lubrication, plus the emission piping, starter, generator, wiring harness, and exhaust silencer. Each figure lists reference numbers, part numbers, quantities, and interchangeability marks keyed to the effective machine number, and a How to read this Parts Catalog page explains the marks.
This is a clean digital PDF with a text layer, so it is easy to search. Use it to match a worn or failed part to its correct number and confirm which components fit your serial range. It is a parts catalog for identification and ordering, not a step-by-step repair manual.
