Part of the Isuzu 4JJ1 engine documentation.
This Isuzu 4JJ1XYSB01 Parts Catalog, publication P-T1140EBC, is the factory parts-identification reference for the 4JJ1 series industrial diesel engine. Its 80 pages organize the engine into illustrated figures, grouped here into gasket and cylinder head, cylinder block and oil system, the rotating assembly, fuel, air and cooling, and the full electrical group.
Every figure shows an exploded diagram tied to reference numbers, part numbers, and quantities, so you can pinpoint the exact component before you order. It reaches down to individual bolt, stud, and gasket sizes, including head-gasket thickness options.
Use it to build accurate parts lists for a rebuild, match part numbers, and avoid ordering the wrong turbocharger, injector, or cooling part. It is a searchable, downloadable PDF you can zoom and print at full size whenever you are working on the engine.
