Hitachi ZAX170W-3 SCM Computer Board – (9274929)

Description

Detail Information

1. Key Features & Benefits

• Genuine Hitachi OEM SCM computer board – Part number 9274929. Manufactured to Hitachi‘s original equipment specifications for the ZAX170W-3, ZX170W-3, and compatible wheeled excavator models. This is the electronic brain of your machine – not a generic aftermarket substitute. The SCM (System Control Module) computer board is the central processing unit that manages and coordinates all electronic functions of your excavator.

• The “excavator control brain” for the entire machine – The SCM computer board is the core electronic control component for Hitachi ZAX170W-3 series wheeled excavators, widely used in urban construction, utility work, and road maintenance. It receives input signals from sensors, joysticks, and switches, processes this data, and sends output commands to actuators, solenoids, and valves throughout the machine. It controls the engine, hydraulic system, transmission, monitor display, and all electronic functions – making it the most critical electronic component on your ZAX170W-3.

• Engineered for the Isuzu 4HK1 engine – The ZAX170W-3 is powered by the Isuzu AI-4HK1X turbocharged, intercooled 4‑cylinder diesel engine, delivering 107 kW (143 HP) at 2,000 rpm with a maximum torque of 540 N·m. The SCM computer board is specifically calibrated for this engine platform, ensuring optimal performance, fuel efficiency, and emissions compliance. The 4HK1 engine meets US EPA Tier 3 and EU Stage IIIA emission standards.

• Intelligent hydraulic and transmission control – The ZAX170W-3 features Hitachi’s advanced hydraulic system with precise electronic control. The SCM computer board continuously monitors hydraulic demand and adjusts pump output in real time to match working conditions. For wheeled excavators that travel on public roads between job sites, the SCM board also manages transmission functions, ensuring smooth gear changes and efficient road travel. This delivers the precise, responsive machine control that Hitachi wheeled excavators are known for – critical for precision grading, trenching near utilities, and fine attachment work.

• Real-time monitoring and fault diagnosis – The SCM computer board continuously monitors all machine systems and records fault codes when issues are detected. When a fault occurs, the controller illuminates the warning indicator on the monitor, enabling rapid diagnosis and reducing downtime. The controller communicates reliably with all machine sensors and actuators.

• Compact and lightweight design – Each SCM computer board weighs approximately 1.17 kg, making it easy to handle and install in the machine’s electronic compartment.

• Plug-and-play replacement – The SCM computer board is a direct replacement for the original Hitachi unit. It connects to the existing wiring harness with standard connectors – no modifications, no adapters. Simple unbolt-and-replace installation.

• Pre-shipment visual verification – Before packing, we send you detailed high‑resolution photographs of the actual unit (connectors, part number markings, overall condition). You approve shipment – we never ship blind. Video inspection is also available upon request.

• Fast delivery – 5–7 working days lead time from our Guangzhou warehouse. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight.

2. Applications

The Hitachi ZAX170W-3 SCM computer board is the electronic brain of this 17‑ton class wheeled excavator, used across a wide range of demanding job sites:

• Urban construction & utilities – Sidewalk repairs, water and gas line trenching, fibre‑optic cable installation, and small‑scale demolition in tight urban spaces. The SCM board’s precise engine and hydraulic control provides smooth, predictable machine response for working near existing structures. The ZAX170W-3 has an operating weight of approximately 17,200 kg and a bucket capacity of 0.52 – 0.82 m³, making it ideal for urban jobs where both mobility and digging power are required.

• Road & bridge maintenance – Shoulder repairs, guardrail replacement, drainage cleaning, and slope stabilisation. The SCM computer board ensures the machine delivers consistent power for road work while managing transmission functions for efficient travel between job sites. The wheeled design allows the ZAX170W-3 to travel on public roads under its own power, reducing transport costs and downtime.

• Residential & commercial development – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The controller‘s precise electronic control provides the “fine‑touch” response needed for working in confined residential spaces.

• Equipment rental fleet – 17‑ton wheeled excavators are frequently rented machines due to their versatility in both road travel and worksite digging. A genuine new SCM computer board provides predictable performance and eliminates the risk of electronic failure – avoiding costly mid‑rental breakdowns, towing bills, and customer complaints.

• Forestry & vegetation clearance – Steep slopes, fallen timber, and uneven terrain place variable loads on the machine. The SCM computer board continuously adjusts engine and hydraulic output to maintain consistent power for saws, grapples, and mulchers.
