Deere 200CLC 225CLC Travel Gearbox 2nd Planetary Carrier Spider With Sun Gear Assy For Excavator Parts 3085985 1027161 3085941

This 2nd stage planetary carrier spider integrated sun gear assembly acts as the core reduction component inside travel final drive gearbox for Deere 200CLC and 225CLC medium excavators, with matched part numbers 3085985, 1027161 and 3085941. Working together with planetary pinions and ring gear, the assembly lowers the high rotating speed output from travel motor and amplifies torque to drive crawler tracks. It is widely used for travel reducer overhaul and worn parts replacement on Deere excavators working in site grading, land clearing, quarry loading and municipal trenching projects. This aftermarket gear assembly is popular with field repair workshops, equipment rental operators and cross-border construction machinery spare parts suppliers.

Under long continuous heavy load, repeated impact from slope climbing and contaminated gear oil, the 2nd stage planetary components tend to suffer gear tooth pitting, carrier spider deformation, spline wear and metal particle generation. Common failure signs include insufficient track traction, slow movement under heavy load, abnormal grinding noise inside travel gearbox, unilateral track drift and final drive overheating. Severe damage to the 2nd planetary carrier and sun gear may jam the reduction system, resulting in excavator immobilization, expensive emergency maintenance and suspended construction progress.

Our planetary carrier spider & sun gear assembly is manufactured strictly in accordance with OEM drawing standards. Gear tooth profile, spline dimension, mounting hole spacing and assembly tolerance fully comply with original specifications. No cutting, reaming or other modification work is needed during on-site installation, allowing service technicians to replace the damaged assembly rapidly and restore normal travel performance. Compared with high-priced genuine spare parts with long delivery cycles, this replacement assembly delivers stable transmission performance and supports bulk repeated purchasing for merchants focusing on Deere medium excavator travel gearbox components.

1. 1:1 dimensional matching for hassle-free field replacement All mounting sizes, spline parameters and gear tooth profile are fully consistent with original parts. The assembly fits perfectly into the travel gearbox of Deere 200CLC / 225CLC, enabling mechanics to complete overhaul without secondary machining and shorten machine downtime.
2. Impact-resistant gear design adapted to rough construction terrain Gear teeth and planetary carrier adopt deep carburizing and quenching technology to raise surface hardness and shock resistance. It can withstand cyclic impact loads generated during turning and climbing on uneven ground, effectively reduce risks of tooth chipping and premature abrasion.
3. Multi-process quality inspection before delivery Each finished assembly will pass gear meshing test, dimensional verification and noise check before packing. Defective products are screened out at factory inspection stage, minimizing rework risk and avoiding sudden travel system failure at construction sites.
4. Budget-friendly aftermarket option for excavator fleet maintenance Genuine planetary transmission parts come with high cost and unstable stock availability. Our factory direct supply balances reliable quality and competitive pricing, helping equipment owners cut down total maintenance expenses for Deere excavator fleets.
5. Diversified logistics solutions for different order demands In-stock goods support quick shipment after payment confirmation. Air freight can be arranged for urgent breakdown orders. Sea consolidation and full container service are available for bulk buyers to save overall logistics cost.

Our factory focuses on R&D and mass manufacturing 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 implemented to verify component durability under real earthmoving and quarry working conditions. Our travel gearbox spare parts are exported to many overseas regions and we maintain long-term stable partnerships with global construction machinery spare part wholesalers.

Q1: Can this 2nd planetary carrier sun gear assembly fit other Deere excavator models? A1: Cross-model installation is not suggested. Different stages of travel gearbox have different gear tooth counts and spline specs. Please confirm machine model and part numbers before placing orders.

Q2: What travel issues can this assembly fix? A2: It solves travel faults caused by worn 2nd stage planetary components: weak traction, slow traveling speed, internal gear grinding sound, track deviation and travel gearbox overheating.

Q3: Can we get volume discount for bulk orders? A3: Yes, preferential price is determined by purchasing quantity. We can arrange full container sea shipment to reduce logistics expenditure.

Q4: What packaging is used for long-distance ocean shipping? 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 parts from collision and rust during overseas transit.
