ZX230 Travel Gearbox 1st Planetary Carrier Spider With Sun Gear Assy | 1027160 3086006 2051204 | Hitachi Excavator Aftermarket Spare Parts

Product Brief

This 1‑stage planetary carrier spider assembly integrated with sun gear, OEM numbers 1027160, 3086006, 2051204, belongs to the first reduction stage inside final drive travel gearbox for Hitachi ZX230 excavator. As one of the core torque‑bearing components of travel reducer, it undertakes power distribution and speed reduction during crawler travelling, supporting heavy‑duty travelling, slope climbing and frequent forward‑reverse switching on construction sites, quarries and earth‑moving projects. This aftermarket assembly is widely purchased by local repair shops, equipment rental firms and cross‑border spare‑part wholesalers for final drive overhaul and worn‑component replacement.
Under long‑term heavy impact load, frequent start‑stop and muddy‑site working conditions, the first planetary carrier unit tends to suffer gear tooth pitting, carrier body deformation, sun‑gear tooth breakage and excessive clearance between matching gears. Typical failure signs include weak travelling power, poor climbing capacity, abnormal rattling or grinding noise from travel gearbox, unilateral slow track speed and overheating of final drive housing. Severe damage will directly lock up travel gearbox and cause machine to lose travelling ability, bringing high downtime loss for construction projects.
Our aftermarket planetary carrier spider with sun gear assembly is manufactured strictly in accordance with original dimension standards for spline size, gear tooth profile, mounting hole position and assembly clearance. No welding, cutting or secondary modification is required for field replacement, direct installation helps shorten equipment idle time. As a cost‑effective substitute for high‑priced original assemblies with long lead‑time, this unit maintains stable load‑bearing performance, satisfying bulk‑order demands for global excavator spare‑part dealers.

Core Technical Indexes

Unique Product Competitive Advantages

1. Precise dimension match for Hitachi ZX230 travel final drive structure Produced following OEM drawing specifications, this carrier assembly keeps consistent spline parameters, gear tooth count and mounting hole spacing. Gear‑meshing clearance is well controlled after assembly, effectively reducing abnormal abrasion and noise inside travel gearbox. No extra machining work needed during on‑site fitting.
2. Reinforced gear tooth heat‑treatment to improve anti‑impact performance Many low‑cost replacement carriers are easy to generate tooth chipping and premature wear under heavy climbing and impact conditions. Our key gear components adopt standardized carburizing quenching process, improving surface hardness and core toughness. It effectively extends service life under cyclic heavy‑load conditions and lowers parts replacement frequency for fleet owners.
3. Strict assembly inspection before delivery to rule out hidden gear‑matching risks Every finished carrier assembly goes through gear‑meshing inspection, clearance detection and appearance check before packing. Defective workpieces are filtered out in factory, avoiding secondary disassembly‑repair work for maintenance teams and unexpected site shutdown risks.
4. Economical aftermarket solution for final‑drive overhaul cost control Genuine OEM planetary carrier assemblies come with high procurement cost and long delivery cycle. Our factory‑direct aftermarket assembly provides reliable comprehensive performance at competitive wholesale price, helping operators cut down overall maintenance expense for medium‑tonnage excavator fleets.
5. Multiple logistics solutions for global wholesale buyers In‑stock goods can be dispatched quickly upon payment confirmation. Air freight is available for urgent breakdown repair orders; consolidated sea freight and full‑container service offer cost‑saving options for long‑term bulk importers.

Factory Production Strength

Our workshop concentrates on manufacturing aftermarket final‑drive components including planetary carrier assemblies, sun gears, planet gears and ring gears for mainstream excavator brands. We own complete production workflows including alloy steel forging, gear hobbing, heat‑treatment, tooth‑surface grinding and finished‑product inspection. Simulation test can simulate real‑site travelling impact load to verify component reliability. Our travel gearbox spare parts are exported to many overseas markets and keep long‑term stable cooperation with global construction machinery spare‑part distributors.

Frequently Asked Customer Questions

Q1: Can this 1027160 1st planetary carrier assembly fit other Hitachi excavator models besides ZX230? A1: Cross‑model installation is not recommended. Different travel gearbox versions have different gear parameters and carrier dimensions. Please double‑confirm machine model and OEM part number before ordering.
Q2: What travel‑system faults can this assembly solve? A2: It fixes failures caused by worn, cracked or deformed first‑stage carrier and sun gear: insufficient travelling power, bad climbing performance, abnormal grinding/rattling noise from travel gearbox, uneven track speed and final‑drive overheating.
Q3: Can you give discount for bulk‑quantity purchase? A3: Yes, tier‑based preferential price is available according to purchase quantity. We can arrange full‑container sea shipment to reduce total logistics cost.
Q4: What packaging is used for long‑distance overseas transportation? A4: Anti‑rust oil is coated on all gear surfaces. Components are wrapped with waterproof shock‑proof PE film, then fixed inside reinforced export plywood case, preventing collision deformation and moisture corrosion during long‑distance transit.
