Travel Gearbox 3rd Planetary Carrier Spider With Sun Gear Assy for Deere 200CLC 225CLC Excavator Parts 1026779 3085966 3085927

Product Brief

This 3rd-stage planetary carrier spider assembled with sun gear serves as the core reduction component inside the travel final drive gearbox for Deere 200CLC and 225CLC medium excavators, corresponding part numbers:1026779, 3085966, 3085927. The assembly works together with planetary pinions and internal ring gear to reduce high rotational speed delivered by travel motor and amplify output torque, supplying steady driving force to crawler tracks. It is widely adopted for travel reducer overhaul and worn component replacement on Deere 200CLC & 225CLC machines deployed in road grading, quarry loading, land clearing and large trenching works. This aftermarket gear assembly gains popularity among local repair shops, equipment rental firms and cross-border construction spare part distributors.

Continuous heavy load operation, frequent climbing impact and contaminated gear oil will gradually trigger gear tooth pitting, carrier deformation, spline abrasion and metal debris generation. Typical failure symptoms include insufficient track traction, slow travel speed when climbing slopes, persistent grinding or clicking noise inside travel gearbox, unilateral track drifting and abnormal heating of final drive. Once the 3rd planetary carrier and sun gear suffer severe damage, the travel reducer may lock up, causing machine immobilization, costly on-site repair and construction schedule interruption.

Our planetary carrier spider & sun gear assembly is fabricated strictly following OEM drawing standards. Gear tooth profile, spline dimension, mounting hole pitch and assembly tolerance are fully consistent with original specs. No cutting, reaming or modification is needed during field installation, allowing service technicians to replace the old assembly quickly and restore normal travel performance. Compared with genuine parts featuring high pricing and long lead times, this replacement assembly maintains reliable transmission stability and supports bulk repeat purchase for merchants focusing on Deere medium excavator travel gearbox spare parts.

Core Technical Indexes

Product Highlights

1. Perfect interchangeability for fast travel system overhaul All mounting sizes, spline parameters and gear tooth profile match original component 1:1. It fits seamlessly into Deere 200CLC /225CLC travel gearbox, helping mechanics complete repair without secondary machining and shorten machine downtime.
2. Reinforced anti-shock gear structure for rough working terrain Gear teeth and planetary carrier adopt deep carburizing quenching craft to lift surface hardness and impact resistance. It can endure recurring shock loads when excavator turns and climbs uneven ground, effectively reduce tooth chipping and premature wear.
3. Strict multi-point inspection before shipment Every finished assembly will pass gear meshing test, dimensional verification and noise detection before packaging. Defective items are eliminated in factory inspection, lowering rework risk and preventing sudden travel breakdown on construction sites.
4. Cost-effective aftermarket spare part for fleet maintenance Genuine planetary transmission components carry high cost and unstable stock supply. Our factory direct supply balances stable quality and competitive price, helping equipment owners cut overall maintenance budget for Deere excavator fleets.
5. Flexible shipping plans to satisfy varied order needs In-stock items support prompt shipment after payment confirmation. Air freight can be arranged urgently for sudden breakdown orders. Sea consolidation and full container service are available for bulk buyers to cut total logistics expense.

Frequently Asked Customer Questions

Q1: Can this 3rd planetary carrier sun gear assembly fit other Deere excavator models? A1: Cross-model installation is not recommended. Different travel gearbox stages differ in gear tooth quantity and spline specifications. Please verify machine model and part numbers before order placement.

Q2: Which travel faults can this assembly resolve? A2: It fixes travel malfunctions caused by worn 3rd stage planetary components: poor traction, slow traveling, internal gear grinding noise, track deviation and travel gearbox overheating.

Q3: Is volume discount available for large bulk orders? A3: Yes, preferential price depends on purchase quantity. We can arrange full container sea shipment to reduce logistics cost.

Q4: What export packaging is adopted 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 from collision and rust during overseas transit.
