Deere 2154D 240DLC 250GLC Travel Gearbox 2nd Planetary Carrier Spider With Sun

This second-stage planetary spider paired with matched sun gear assembly serves as the intermediate torque conversion unit housed inside the travel final drive for Deere 2154D, 240DLC and 250GLC crawler excavators. It is widely used in logging land clearing, port material stacking, highway foundation works and urban basement excavation projects, satisfying regular maintenance demands for equipment rental businesses, field service garages and cross-border spare parts distributors serving Africa, Southeast Asia and the Middle East markets.

Positioned in the middle reduction section of multi-stage travel gearbox, this planetary assembly undertakes power transmission and torque adjustment between the primary and tertiary gear sets. It endures continuous alternating impact loads generated during frequent direction changes, full-load travelling and uphill operation. Common failure conditions include fatigue cracking of carrier support lugs, sun gear tooth chipping and surface pitting, as well as excessive abrasion of internal connecting splines. Once the assembly becomes damaged, the excavator will display obvious operational defects such as weak travelling power, speed discrepancy between left and right tracks, persistent metallic grinding noise inside the reducer and abnormal overheating of the travel gearbox. Unplanned equipment downtime will interrupt construction timelines and increase emergency repair and component replacement costs for project contractors and equipment asset owners.

Our assembly is fabricated to OEM equivalent standards for gear tooth profile, spline fitting clearance and overall mounting dimension. No secondary cutting, drilling or structural modification work is needed during travel gearbox overhaul, enabling direct replacement installation and minimizing machine downtime. As an economical aftermarket substitute for high-priced genuine spare parts with unstable supply cycles, this assembly maintains reliable torque transmission with factory wholesale pricing, well suited for bulk procurement by cross-border construction machinery component suppliers.

1. Precise dimensional replication, dedicated for Deere 2154D, 240DLC, 250GLC travel reducer, non-interchangeable with other excavator models This planetary assembly is customized according to the internal cavity size of the corresponding travel gearbox and cannot be fitted onto other machine models. Accurate control over spline tolerance and gear meshing gap prevents transmission jitter, track deviation and accelerated wear of matched transmission components after installation, and no extra auxiliary fittings are required during assembly.
2. One-piece integral forging structure, excellent impact resistance for frequent heavy-load construction tasks Many low-cost generic planetary carriers easily suffer lug fracture and gear tooth collapse under frequent start-stop impact loads. Our integral forging process combined with standardized heat treatment improves overall structural toughness and extends working service life. It keeps stable power output during repeated moving and digging cycles, helping rental fleets cut down the overall overhaul frequency of travel gearboxes.
3. Strict whole-process factory quality control to lower risks of unplanned machine halt Every finished assembly passes full dimension inspection and load simulation testing before shipment. Defective semi-finished products are screened out in advance, avoiding rework troubles for maintenance teams and economic losses triggered by sudden equipment breakdown on construction sites.
4. Cost-effective aftermarket option to manage routine equipment maintenance budgets Genuine original planetary spare parts usually carry high prices and long lead times. Our aftermarket assembly reaches equivalent load capacity and service lifespan as OEM components at factory direct price, lowering annual maintenance expenditure for enterprises operating multiple excavators.
5. Multiple global logistics choices for bulk wholesale buyers In-stock goods can be arranged for delivery within 3 working days after payment confirmation. Air freight satisfies urgent emergency repair orders; consolidated sea freight and full-container shipment provide economical bulk purchasing solutions for long-term distributors.

Our manufacturing workshop focuses on the research and production of planetary gear spare parts for travel gearboxes of various excavator brands. We own a complete production chain covering alloy steel die forging, precision gear machining, professional heat treatment and finished product performance testing. The independent torque simulation test bench replicates harsh real-site working conditions to continuously optimize product wear resistance and impact tolerance. Our planetary gear assemblies are exported to many overseas regions and maintain long-term stable cooperative relations with global construction machinery spare parts wholesalers.

Q1: Can this second-stage planetary carrier assembly fit excavator models outside Deere 2154D, 240DLC, 250GLC? A1: Cross-model installation is not supported. Different excavator models adopt final drive assemblies with different structural sizes and spline specifications. Please confirm your machine model and corresponding part numbers before placing orders.

Q2: Which travel gearbox failures can this assembly fix? A2: It resolves malfunctions caused by cracked carrier lugs, broken or worn sun gear teeth, inconsistent track travelling speed, internal metal grinding noise and insufficient traction while climbing slopes.

Q3: Do you offer tiered discounts for large wholesale orders? A3: Yes, differentiated preferential prices are provided based on purchase volume. We can also arrange full-container sea transport to reduce comprehensive logistics costs.

Q4: What packaging is adopted for long-distance ocean transportation? A4: Heavy-duty anti-rust grease is evenly coated on all metal surfaces. The whole assembly is wrapped with waterproof and shockproof PE film, then sealed inside reinforced export plywood cases to prevent collision deformation and moisture corrosion during long overseas transit.
