Deere 450DLC 450LC Travel Gearbox 1st Planetary Carrier Spider With Sun Gear Assy For Excavator Parts 1015505 3053098 2044685

This 1st‑stage planetary carrier spider assembled together with sun gear acts as the core reduction transmission component inside travel gearbox for Deere 450DLC and 450LC large‑frame excavators. It takes output torque from travel motor, executes speed reduction and torque multiplication, and delivers powerful tractive force for heavy‑load travelling, slope climbing and on‑site slewing movement. Widely applied in large‑scale quarry mining, heavy earth‑moving and infrastructure foundation projects, this aftermarket replacement assembly is widely sourced by overseas repair depots, equipment leasing companies and cross‑border spare‑part wholesalers for final drive disassembly overhaul and direct worn‑component replacement on Deere heavy‑duty excavator fleets.

Operating under sustained high torque output, impact load and degraded gear‑oil lubrication on tough construction sites, the original planetary carrier assembly will suffer gear tooth pitting, spline surface wear, carrier spider deformation and sun‑gear tooth cracking after long‑time service. Common failure manifestations include insufficient travel pulling force, track offset running, clattering metallic noise inside travel reducer, travel gearbox housing overheating and track jerking during movement. Once the assembly suffers severe damage, the travel system may lock up, forcing the machine out of service and bringing high on‑site repair cost and project schedule delay for equipment operators.

Our replacement planetary carrier and sun gear assembly strictly follows original component benchmarks for carrier structure, gear tooth profile, spline dimension and mounting layout. No cutting, welding or extra adaptor modification is required during field installation, allowing service technicians to complete final‑drive repair efficiently and cut machine downtime greatly. Compared with high‑cost genuine OEM units with long order lead‑time, this assembly provides steady transmission performance and meets bulk purchasing demands for global dealers focusing on Deere large excavator final‑drive spare parts.

1. Precision‑matched dimension to support quick on‑site final‑drive repair All gear tooth parameters, spline sizes and mounting hole positions keep consistent with original specifications. Maintenance crews can finish assembly swap inside travel gearbox without secondary machining work, lifting repair efficiency for heavy excavator overhaul and pre‑owned equipment refurbishment assignments.
2. Forged heavy‑load‑resistant structure for large excavator harsh operating environment Many low‑cost cast replacement parts are prone to tooth chipping and carrier deformation under sudden impact torque. Our carrier spider adopts alloy steel forging plus full tooth‑surface hardening treatment, improving impact resistance and fatigue resistance, lowering part replacement frequency for Deere 450DLC / 450LC machines working in quarry sites and high‑intensity earth‑moving jobs.
3. Multi‑item inspection for each finished assembly prior to delivery Every planetary carrier assembly passes tooth‑profile detection, spline tolerance verification and gear meshing noise test before packing. Defective workpieces are screened out inside factory, decreasing re‑work risks for repair teams and avoiding unexpected travel‑system breakdown on construction jobsites.
4. Economical aftermarket selection for heavy‑duty excavator fleet management Genuine original planetary carrier assemblies for Deere 450‑series excavators carry steep purchase price and unstable stock availability. Our factory‑direct replacement assembly balances reliable transmission performance and competitive cost, helping equipment owners and service workshops lower total maintenance spending for large excavator fleets.
5. Flexible logistics solution for bulk‑purchase traders In‑stock goods support fast shipment once payment is confirmed. Air freight service is available for urgent emergency repair orders. Sea consolidation and full‑container transport options help overseas bulk buyers reduce overall logistics expenditure.

Our manufacturing facility concentrates on R&D and mass manufacturing of final‑drive transmission spare parts for large‑size excavators, covering multi‑stage planetary carrier groups, sun gears, planet gears and internal travel gearbox components. We own complete production workflows: alloy‑steel forging, precision gear machining, professional heat‑treatment and finished‑product tolerance inspection. Simulated heavy‑torque cyclic load tests are performed to validate component durability under real‑world quarry and earth‑moving working scenarios. Our spare parts are exported to numerous overseas regions and maintain long‑term stable cooperation partnerships with global construction‑machinery spare‑part wholesalers.

Q1: Will this 1015505 3053098 2044685 planetary carrier assembly fit other Deere excavator models? A1: Cross‑model fitment is not recommended. Different travel gearbox assemblies differ in gear modulus, spline specs and carrier overall dimension. Please double‑verify machine model and old part number before placing orders.

Q2: What travel‑drive faults can this planetary carrier plus sun gear assembly solve? A2: It addresses failures caused by gear and carrier wear: inadequate travel power, track drifting, abnormal knocking noise inside final drive, travel gearbox overheating and intermittent track stalling.

Q3: Can I get volume‑based discount for large quantity orders? A3: Yes, tiered preferential price is offered according to order volume. Full‑container sea freight arrangement can be supported to cut comprehensive logistics cost.

Q4: What export‑standard package is used for long‑distance overseas transportation? A4: Anti‑rust oil is sprayed over all gear and spline surfaces. The complete assembly is wrapped by anti‑rust paper and shock‑absorbing PE foam, then fixed inside heavy‑duty plywood case, protecting gear teeth against collision damage and rust formation in long‑haul ocean transit.
