Essential Insight
The Hanix N120 mini excavator, also known under the Nissan N120 label, is a grey market machine with limited parts support in North America. While components like the pinion and ring gear for the swing table are still available overseas, high shipping costs and import duties make maintenance expensive and logistically complex.
Hanix N120 Background and Market History
The Hanix N120 was manufactured by Nihon Automotive, later rebranded as Hanix, and distributed under various names including Nissan in select regions. These compact excavators were designed for tight urban work, landscaping, and utility trenching. With an operating weight around 2.5–3 tons and a swing boom configuration, the N120 offered impressive maneuverability and digging power for its class.
During the late 1980s and early 1990s, a batch of these machines was imported into North America—often without full dealer support or documentation. Many were sold through secondary channels, leading to their classification as “grey market” units. This designation means they were not officially supported by the manufacturer in the region where they were sold.
Common Parts Issues and Component Identification
In Michigan, an operator acquired a Hanix N120 from a local auction. After discovering the swing table gear was stripped, he contacted U.S. Nissan dealers—only to learn they did not support the model. He eventually sourced the gear set from a UK supplier, but paid nearly $400 in shipping and customs fees. He now stocks critical wear parts and logs part numbers for future reference.
Recommendations for Owners
Owning a Hanix N120 mini excavator offers compact power and versatility, but parts sourcing requires persistence and creativity. With limited domestic support, operators must rely on overseas suppliers, dimensional matching, and community knowledge. By documenting components and planning ahead, even grey market machines can be maintained effectively for years of productive service.

Common Parts Issues and Component Identification
- Swing table gear set
The pinion and ring gear are critical for rotation. Wear or damage leads to jerky movement or complete failure. These parts are not interchangeable with other brands and must match Hanix specifications.
- Hydraulic seals and cylinders
While some seals can be matched by size, cylinder assemblies often require OEM parts due to unique mounting and stroke dimensions.
- Electrical components
Wiring harnesses and control modules may differ from domestic models. Voltage ratings and connector types must be verified before replacement.
- Undercarriage components
Track rollers, sprockets, and idlers can sometimes be sourced from aftermarket suppliers using dimensional matching.
- UK and Ireland dealers
Hanix Europe maintains parts inventories for legacy models. Plant Parts Ltd in Hadleigh, UK is one known supplier. They offer swing gear sets, hydraulic components, and electrical parts.
- Keyword search optimization
Use terms like “mini digger spares,” “Hanix plant parts,” or “N120 swing gear” when searching online. European terminology differs from North American conventions.
- Aftermarket alternatives
Some parts like filters, seals, and bushings can be matched using industrial catalogs. WIX, Parker, and SKF offer equivalents for common wear items.
- Shipping and import fees
While part prices may be reasonable, shipping from Europe and U.S. import duties can double the total cost. Consolidating orders and using freight forwarders may reduce expenses.

Recommendations for Owners
- Build a parts binder with photos, dimensions, and supplier contacts.
- Keep a stock of common wear items: filters, seals, pins, bushings.
- Use calipers and micrometers to measure parts for aftermarket matching.
- Join online forums and owner groups to share sourcing tips.
- Consider fabricating non-critical components locally if specs are known.
