| High Light | Hitachi ZX230 travel gearbox planetary carrier ，excavator planetary gear spider with sun gear ，Hitachi excavator parts planetary carrier assembly | ||
This 3rd stage planetary carrier spider integrated with sun gear assembly is a core reduction component for the travel final drive gearbox of Hitachi ZX230 excavator, with part numbers 1026779, 3085966 and 3085927. Installed inside the travel gearbox, it works together with planetary gears and ring gear to reduce high speed output from travel motor and amplify torque, delivering powerful driving force to crawler tracks. This assembly is widely used for overhaul and replacement of travel reducer on ZX230 machines working in quarry mining, road construction, earthmoving and site grading projects. It is favored by repair workshops, equipment leasing firms and global excavator spare parts distributors.
Long hours of heavy load operation, impact force during climbing and mixed impurities in gear oil will gradually cause tooth surface pitting, gear abrasion, carrier deformation and spline wear. Common failure symptoms include weak traction, excavator crawling slowly on slopes, abnormal clicking or grinding noise inside travel gearbox, unilateral track deviation and overheating of final drive. Severe damage to the 3rd planetary carrier & sun gear will lock the travel gearbox directly, leading to machine immobilization and costly site downtime.
Our planetary carrier spider and sun gear assembly is manufactured strictly according to original OEM dimension standard. Tooth profile, spline size, mounting hole spacing and assembly tolerance fully match original specs. No modification, cutting or reaming work needed for installation. Mechanics can replace the old assembly quickly to restore normal travel performance. Compared with original parts with long lead time and high price, this aftermarket assembly keeps stable transmission performance and supports bulk purchase for merchants focusing on Hitachi medium excavator undercarriage and travel gearbox spare parts.

Our factory specializes in manufacturing planetary gear assemblies, sun gears and carrier spiders for excavator travel reduction gearbox. We own complete production lines including alloy forging, precision machining, heat treatment and finished product testing. We carry out cyclic load simulation test to verify durability under actual construction working conditions. Our travel gearbox spare parts are exported to many overseas markets and maintain long-term cooperation with construction machinery spare part wholesalers.
Q1: Can this 3rd planetary carrier and sun gear assembly fit other Hitachi excavator models? A1: Cross-model installation is not recommended. Different travel gearbox stages have different gear teeth and spline parameters. Please confirm machine model and part numbers before ordering.
Q2: What problems can this assembly solve? A2: It fixes travel faults caused by worn 3rd stage planetary components: weak traction, slow traveling, gear grinding noise, track drifting and travel gearbox overheating.
Q3: Will volume discount be offered for bulk orders? A3: Yes, discount price depends on purchase quantity. We can arrange full container sea shipment to reduce logistics expense.
Q4: What packaging is adopted for long-distance export transport? A4: Anti-rust oil is coated on all gear tooth surfaces. The assembly is wrapped with waterproof anti-rust film and shockproof foam, then fixed inside reinforced plywood case to avoid collision and rust during ocean transit.
