Hitachi ZX210-3 Wheel Excavator Travel Assembly 4664223 – Japanese Genuine (Complete Portal Axle Drive Set)

3. Applications

The Hitachi ZX210‑3 wheel excavator with the 4664223 travel assembly is a 20‑ton class machine used in mixed road and off‑road applications where mobility and traction are equally critical.

• Municipal utility & pipeline work – Wheel excavators are preferred for city water, gas, fibre‑optic, and electrical projects because they travel on paved roads under their own power between work points. The 4664223’s two‑speed capability allows high‑speed road travel without a low‑boy trailer, then switches to low‑speed high‑torque for trenching and backfilling.

• Highway & bridge maintenance – Shoulder repair, guardrail replacement, drainage cleaning, and slope stabilisation require the machine to drive long distances along the highway. The wheel drive system must withstand sustained high‑speed rotation and heat build‑up. A genuine Japanese travel assembly delivers that reliability.

• Port & container handling – At cargo terminals and container yards, wheel excavators move between storage rows, load/unload containers, and clear spillage. The constant stop‑start and tight turning place high demand on the wet brake system and planetary gears.

• Agriculture & land improvement – Farm drainage, pond cleaning, and irrigation trenching involve working in soft, muddy fields after traveling on farm roads. The planetary wheel end’s sealing system keeps water and silt out of the gear oil, preventing premature bearing failure.

• Mine support & site maintenance – Large open‑pit mines use wheel excavators for road grading, dust control, and equipment pad maintenance. Sharp rock fragments and abrasive dust accelerate wear on floating seals; genuine Japanese seals provide the best resistance.

• Equipment rental fleet – Rental machines see mixed use by multiple operators. A fresh wheel travel assembly with intact seals and new bearings restores full travel performance and eliminates customer complaints about leaking hubs or noisy wheel ends.

Warranty note: Warranty period is 3 to 6 months depending on product details. We do not provide warranty service for genuine original parts. Our value is delivered up front: genuine Japanese sourcing, new‑condition components, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote aftermarket alternatives – please ask our sales team.

Critical installation & oil tip for wheel travel assemblies:
– Do not use hydraulic oil in the planetary side. The wheel end reduction gearbox requires gear oil (SAE 90 or 80W‑90, API GL‑4 or GL‑5). Hydraulic oil lacks extreme‑pressure additives and will cause rapid gear and bearing wear.
– The floating seals are pre‑installed. Do not strike or pry the seal seating surfaces when mounting the wheel hub.
– Before starting the engine, verify that the case drain line is clear and unrestricted. A blocked case drain will blow the motor shaft seal instantly.
– After installation, cycle the travel controls at low idle to purge air from the brake release circuit. The machine may not move initially until the system is bled.

The wheel travel assembly is the only link between hydraulic power and the road on your ZX210‑3. When the wheel end leaks, the brake drags, or the motor loses power, your 20‑ton wheel excavator becomes a roadside hazard. A genuine Japanese 4664223 travel assembly from Hongtengda Parts gets your machine back on the job – on the highway and in the trench.
