What This Engine Parts Catalog Covers

The Hitachi ZAXIS 870-5G Series Isuzu 6WG1-XQA04 Engine Parts Catalog is a complete illustrated guide to the engine components used in the ZAXIS 870-5G, ZAXIS 870LC-5G, ZAXIS 870H-5G, ZAXIS 870LCH-5G, and ZAXIS 870LCR-5G hydraulic excavators. It covers the Isuzu 6WG1-XQA04 diesel engine from serial number 050001 onward.

The catalog is divided into engine assembly groups, each containing a detailed exploded-view drawing keyed to an itemized parts list. The parts lists include part numbers, part names, quantities per engine or assembly, service codes, serial number ranges, interchangeability codes, and replaceable part numbers with quantities. This structure allows a technician or parts specialist to identify exactly which component is used on a specific machine serial number and whether a substitute part is available.

Major systems covered include the cylinder head and valvetrain, cylinder block and liner set, crankshaft and piston assemblies, flywheel and timing gear case, oil pan and level gauge, camshaft and valve mechanism, timing gears, inlet and exhaust manifolds, ventilation system, water pump and thermostat, water piping, fan and fan belt drive, turbocharger system and turbocharger unit, air compressor and piping, fuel injection system and injection pump, governor and feed pump, fuel filter and fuel piping, oil cooler and oil filter, oil pump and oil strainer, engine electrical control parts, starter, generator, and the water sedimenter.

Because this is a parts catalog, every page is built around part identification and ordering rather than repair procedures. The exploded-view illustrations are designed to show how components fit together, which helps when disassembling an engine or verifying that the correct part is being ordered. The serial number columns indicate when a part was introduced or changed, so buyers can match parts to their exact machine build.

Who This Parts Catalog Is For

This PDF is intended for Hitachi ZAXIS 870-5G owners, fleet maintenance managers, diesel mechanics, parts counter staff, and rebuilders working with the Isuzu 6WG1-XQA04 engine. It is also useful for anyone performing an engine overhaul, top-end rebuild, turbocharger replacement, fuel system service, cooling system repair, or electrical component replacement on these machines.

When ordering engine parts for a ZAXIS 870-5G, having the correct part number is critical. The catalog provides the exploded views and itemized lists needed to trace a component back to its exact part number, including superseded and interchangeable options. The multilingual format makes the document usable across different regions where these excavators were sold and serviced.

Get the Right Part the First Time

Engine downtime on a 87-tonne-class excavator is expensive. Waiting on a wrong part because the number was guessed or pulled from an outdated source adds days to a repair.

Whether you are resealing a cylinder head, replacing a turbocharger, servicing the injection pump, or rebuilding the oil cooler assembly, the exploded views and parts lists in this catalog help you identify every gasket, bolt, bearing, and assembly involved.
