This complete third‑stage planetary spider carrier pre‑assembled with sun gear carries the peak torque output inside travel final drive for Deere 180GLC, 200DLC and 225DLC medium‑size excavators. As the last reduction stage of travel gearbox, this assembly transfers high torque to crawler tracks, supporting rough‑terrain travelling, steep slope climbing and heavy‑load relocation in municipal construction, site development and quarry working environments. It is a core replacement component during final drive overhaul, widely stocked by cross‑border spare‑part traders, on‑site repair workshops and equipment rental companies.
Under long‑term low‑speed heavy‑torque impact, frequent forward‑reverse switching and contaminated gear oil conditions, the 3rd‑stage carrier and matched sun gear are vulnerable to tooth pitting, spider body distortion, spline wear and enlarged gear backlash. Typical failure signs include weak track driving power, poor uphill performance, persistent metallic grinding noise inside travel gearbox, uneven track speed and final drive housing overheating. Once gear teeth crack or chip, metal debris will pollute the whole gearbox chamber, damage adjacent planetary components and even lock up travel unit, resulting in costly project downtime.
Our aftermarket carrier spider and sun gear assembly strictly complies with OEM dimensional standards for spline profile, gear tooth parameters, mounting hole layout and assembly backlash. No welding, cutting or extra adapter modification is needed for field installation, direct drop‑in fit greatly cuts machine idle time. As a practical cost‑saving substitute for high‑priced original assemblies with long procurement lead‑time, this unit delivers reliable heavy‑torque bearing capacity, satisfying bulk‑order purchasing demands for global construction machinery spare‑part suppliers.

1. Accurate dimension matching for Deere 180GLC / 200DLC / 225DLC travel final‑drive reducer Produced against original component drawing specifications, this assembly keeps consistent spline specification, gear tooth count and mounting hole spacing. Pre‑calibrated meshing backlash effectively reduces internal abrasion and vibration noise inside travel gearbox, no secondary machining work required during on‑site fitting.
2. Optimized gear heat‑treatment craft oriented for heavy‑torque working scenarios Many low‑cost replacement carriers suffer tooth chipping and rapid abrasion under climbing and overload impact. Our critical gear components adopt mature carburizing quenching process, balancing surface hardness and core toughness. It extends service life under sustained heavy‑torque cycles and reduces parts‑replacement frequency for excavator fleets.
3. Rigorous finished‑goods inspection before delivery to eliminate hidden transmission risks Each finished carrier assembly undergoes gear‑meshing test, backlash measurement and appearance inspection prior to packing. Defective workpieces are filtered out in factory, lowering re‑assembly labor burden for maintenance technicians and preventing unexpected jobsite breakdown losses.
4. Cost‑effective aftermarket option for final‑drive overhaul budget management Genuine OEM planetary carrier assemblies come with high procurement cost and lengthy delivery cycle. Our factory‑direct‑supply aftermarket assembly provides dependable comprehensive performance at competitive wholesale price, helping operators cut overall maintenance expenditure for medium‑tonnage excavator fleets.
5. Multiple flexible logistics solutions for global wholesale customers In‑stock goods can be dispatched quickly upon payment confirmation. Air freight supports urgent breakdown repair orders; consolidated sea freight and full‑container service offer cost‑saving selections for long‑term bulk importers.

Our manufacturing workshop focuses on producing aftermarket final‑drive spare parts covering planetary carrier assemblies, sun gears, planet gears and ring gears for mainstream excavator brands. We possess complete production workflows: alloy steel forging, gear hobbing, professional heat‑treatment, tooth‑surface grinding and finished‑product inspection. Dedicated simulation equipment reproduces real‑site low‑speed heavy‑torque impact load to verify component reliability. Our travel‑gearbox spare‑parts are exported to multiple overseas markets and maintain long‑term stable cooperation with global construction‑machinery spare‑part distributors.

Q1: Can this 1025875 third‑stage planetary carrier assembly fit other Deere excavator models besides 180GLC, 200DLC, 225DLC? A1: Cross‑model installation is not recommended. Different travel gearbox versions adopt different gear parameters and carrier dimensions. Please double‑confirm machine model and OEM part number before submitting orders.
Q2: What travel‑system malfunctions can this assembly resolve? A2: It fixes failures triggered by worn, cracked or deformed third‑stage carrier and sun gear: insufficient travel driving force, bad climbing performance, abnormal grinding or rattling noise of travel gearbox, inconsistent track speed and final‑drive overheating.
Q3: Is volume‑based discount available for bulk‑quantity orders? A3: Yes, tier‑based preferential price is offered subject to purchase quantity. We can arrange full‑container sea shipment to reduce total logistics expense.
Q4: What packaging is adopted 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 secured inside reinforced export‑grade plywood case, preventing collision deformation and moisture corrosion during long‑haul transit.
