This parts catalog covers the Isuzu 4JG1-TPA diesel engine fitted to the Takeuchi TL140 track loader. Its 77 pages break the engine into illustrated figures, from the gasket kit, cylinder head, and block through the camshaft, crankshaft, fuel injection system, injection pump and governor, cooling, and electrical parts.
Each figure pairs an exploded diagram with item numbers, part numbers, and quantities, so you can identify the exact component before ordering. This is a mechanical injection-pump engine, and the catalog details the pump, governor, nozzles, and their shims down to individual thicknesses.
Use it to build accurate parts lists for a rebuild, order the correct shims and gaskets, and match part numbers for this specific engine. It is a bilingual Japanese and English PDF you can download, search, zoom, and print whenever you service the engine.
