About IHI Construction Machinery

IHI Corporation is one of Japan's most distinguished and long-established industrial engineering companies, with a corporate history stretching back to 1853 — making it one of the oldest continuously operating industrial enterprises in Japan and one of the oldest engineering companies in Asia. Founded in Tokyo during the final years of the Edo period, IHI — originally known as Ishikawajima Shipbuilding and Engineering — began as a shipbuilding company at the dawn of Japan's industrial modernisation, building vessels for Japan's expanding naval and commercial maritime fleet during a period of extraordinary national transformation.

Over the following century and a half, IHI grew and diversified far beyond its shipbuilding origins to become one of Japan's largest and most technically capable industrial conglomerates, with major business divisions spanning aerospace, energy, industrial machinery, transportation infrastructure, and precision machinery. IHI's engineering credentials are particularly distinguished — the company has been involved in the development and manufacture of aircraft engines, rocket propulsion systems, and industrial gas turbines, giving IHI a depth of precision engineering expertise and manufacturing capability that few industrial companies in the world can match.

IHI entered the construction machinery business by leveraging its deep precision engineering expertise into the design and manufacture of hydraulic excavators — machines that demand the same high standards of hydraulic system engineering, structural integrity, and manufacturing precision that IHI had developed across its other industrial divisions. IHI Construction Machinery Co., Ltd. went on to produce a well-regarded range of hydraulic excavators that earned a strong reputation across Asian and global construction markets for reliability, hydraulic performance, and durability in demanding operating conditions.

IHI excavators — including the popular IS, UE, and 50N series — were widely used across construction, civil engineering, and earthmoving projects in Australia and throughout the Asia-Pacific region. While IHI Construction Machinery was later acquired by Sumitomo Construction Machinery, the large installed base of IHI excavators still operating across Australia means that demand for quality IHI excavator parts remains strong. Keeping these proven and capable machines operational requires access to a reliable supply of genuine and aftermarket parts from a supplier with the knowledge and sourcing capability to find what you need.

Genuine vs Aftermarket IHI Excavator Parts — Which Should You Choose?

Genuine IHI OEM parts are manufactured to the exact engineering specifications of your machine and are the recommended choice for critical components such as hydraulic pumps, swing bearings, engine components, and electronic control units. For an older IHI excavator still in productive service, genuine OEM parts provide the assurance of correct fit and reliable performance that protects your machine and your investment.

For high-frequency consumable items such as bucket teeth, cutting edges, track shoes, undercarriage components, filters, and hydraulic seal kits, quality aftermarket IHI-compatible parts offer a cost-effective alternative that delivers equivalent performance at a lower price point. This is particularly relevant for older IHI excavator models where OEM parts availability through dealer networks may be limited or carry significant price premiums due to low volume demand.

At Lucas Parts, we supply both genuine and premium aftermarket IHI excavator parts, giving you the flexibility to make the right choice for each component based on criticality, budget, and your machine's operating condition. Our team is happy to advise you on the best option for your specific IHI excavator model and application.
