Hitachi ZX200 Travel Gearbox 1st Planetary Carrier Spider With Sun Gear Assy For Excavator Parts 1025826 3082148 2042351

This 1st stage planetary carrier spider together with sun gear assembly functions as the primary reduction component inside travel final drive gearbox of Hitachi ZX200 excavator, with matching part numbers 1025826, 3082148 and 2042351. Cooperating with planetary pinions and inner ring gear, the assembly reduces high-speed rotation output from travel motor and multiplies torque, delivering steady driving force for crawler tracks. This component is widely used for travel reducer overhaul and replacement of worn-out parts on ZX200 excavators operating in earthmoving, quarry loading, road reconstruction and land leveling projects. It is well accepted by local repair shops, equipment rental businesses and cross-border excavator spare parts distributors.

During prolonged heavy-load operation, continuous impact when climbing slopes, plus deteriorated and contaminated gear oil, the 1st stage planetary components are prone to gear tooth pitting, carrier deformation, spline wear and metal debris buildup in the gear housing. Typical failure signs include insufficient track traction, weak power when climbing slopes, unusual rattling or grinding noise inside travel gearbox, single-side track drifting and excessive heat of final drive. Once the 1st planetary carrier and sun gear suffer severe damage, the reduction system may lock up, making the excavator unable to travel, bringing expensive emergency repair cost and halting construction schedules.

Our planetary carrier spider & sun gear assembly is produced strictly following OEM drawing standards. Gear tooth profile, spline dimension, mounting hole spacing and assembly tolerance fully comply with original specifications. No cutting, reaming or modification work is needed during field installation. Maintenance technicians can replace the old assembly quickly and restore normal travelling performance. Compared with costly genuine spare parts with long delivery cycles, this aftermarket assembly maintains stable transmission performance and supports bulk repeated orders for suppliers specialized in Hitachi medium excavator travel gearbox spare parts.

1. 1:1 OEM dimension interchangeability for fast field replacement All mounting sizes, spline parameters and gear tooth profile match original parts perfectly. It can be installed directly into Hitachi ZX200 travel gearbox, allowing mechanics to finish overhaul without secondary machining and minimize machine downtime.
2. Heavy-load resistant gear design for rough construction terrain Gear teeth and planetary carrier adopt deep carburizing quenching technology to improve surface hardness and shock resistance. It can endure cyclic impact loads from turning and climbing on uneven ground, effectively lower the risk of tooth chipping and premature wear.
3. Strict multi-step quality inspection before shipment Each finished assembly passes gear meshing test, dimensional verification and noise inspection before packing. Defective goods are screened out in factory inspection, reducing rework possibility and avoiding sudden travel breakdown on construction sites.
4. Affordable aftermarket option for excavator fleet maintenance Genuine planetary transmission components have high price and unstable stock. Our factory direct supply balances reliable quality and competitive price, helping equipment owners cut overall maintenance budget for Hitachi excavator fleets.
5. Diverse logistics plans for different order requirements In-stock items can be shipped rapidly after payment confirmation. Air freight service is available for urgent breakdown orders. Sea consolidation and full container shipment are offered for bulk buyers to reduce total logistics cost.

Our factory devotes to R&D and mass production of planetary carrier, sun gear and related gear assemblies for excavator travel reduction gearbox. We have complete production lines covering alloy forging, precision machining, heat treatment and finished product testing. Cyclic load simulation tests are conducted to check durability under real earthmoving and quarry working conditions. Our travel gearbox spare parts are exported to many overseas markets, and we maintain long-term stable cooperation with global construction machinery spare part wholesalers.

Q1: Can this 1st planetary carrier sun gear assembly fit other Hitachi excavator models? A1: Cross-model installation is not recommended. Different stages of travel gearbox feature different gear tooth quantities and spline specs. Please confirm machine model and part numbers before placing orders.

Q2: What travel faults can this assembly solve? A2: It fixes travel problems caused by worn 1st stage planetary components: insufficient traction, slow travelling speed, internal gear grinding noise, track deviation and travel gearbox overheating.

Q3: Is volume discount available for bulk orders? A3: Yes, preferential price is based on purchasing quantity. We can arrange full container sea shipment to save logistics expense.

Q4: What packaging is used for long ocean transportation? A4: Anti-rust oil is coated on all gear tooth surfaces. The assembly is wrapped with waterproof anti-rust film and shock-absorbing foam, then fixed inside reinforced plywood case to protect precision components against collision and rust in overseas transit.
