Doosan DH35 Final Drive Travel Motor Assembly – TM04 (OEM 2401-9285 / 401-00023)

Crawler track propulsion on the 3.5-ton Doosan DH35 and Daewoo Solar 035 mini excavator requires high-output tractive effort to drive 300mm rubber tracks through mud trenches and onto transport trailers. Tatan Machinery supplies 100% Brand New TM04 complete final drive travel motor assemblies (OEM part numbers: 2401-9285 / 2401-9285A, interchangeable with 401-00023 / 401-00456). Combining an automatic two-speed axial piston hydraulic motor with an enclosed multi-stage planetary reduction gearbox, each unit is equipped with heavy-duty duo-cone mechanical floating seals and an internal wet-disc parking brake pack. Backed by our 12-Month Comprehensive Replacement Warranty.

Step 1: Confirm Final Drive Identification & Wholesaler Standard

Tatan Machinery is a verified first-party physical stocking wholesaler of excavator components. All our hydraulic pumps, main valves, and travel drives are 100% Brand New (our diesel engine assemblies are remanufactured to OEM tolerances).

Step 2: Verify Track Frame Fitment & Sprocket Bolt Pattern

The 2401-9285 track drive serves several Doosan/Daewoo 3-ton to 4-ton mini excavator models. Review your chassis setup below:

Step 3: Inspect Actual Product Build & Planetary Mechanism

This final drive is 100% Brand New with zero operating hours. We do NOT sell resealed salvage yard drives. Key internal mechanical specifications include:

• Two-Stage Planetary Gear Train: Hardened alloy steel sun pinions and planet gears designed to deliver high drawbar pull without tooth root pitting.
• Mechanical Duo-Cone Floating Seals: High-chrome alloy floating face seals tested to resist fine construction slurry, weeds, and sand intrusion.
• Integrated Counterbalance Valve: Motion control check valve manifold prevents runaway when tracking down steep slopes or loading onto transport ramps.

Step 4: Watch Live Warehouse Inventory & Physical Stock Video

Because this is a 100% Brand New hydraulic component (only our diesel engine assemblies are remanufactured), we document our physical warehouse stockholding, palletized inventory, and port-sealing quality directly on camera:

Step 5: Review 12-Month Quality Warranty Protection

Every 100% Brand New 2401-9285 final drive supplied by Tatan Machinery comes backed by our 12-Month Comprehensive Replacement Guarantee:

• Full Planetary & Motor Integrity Coverage: Planetary gear fracture, sun shaft shear, motor cylinder barrel cracks, and internal parking brake failure resulting from manufacturing defects.
• Direct Replacement Support: If any defect occurs under proper maintenance, we dispatch immediate replacement components or complete drive assemblies without lengthy disputes.

Step 6: Heavy Export Packaging Protocol

A heavy 55 kg final drive requires reinforced industrial packaging to survive ocean transit without shift or moisture penetration:

• Threaded Metal Port Plugs: Main travel ports, case drain line, and 2-speed shift signal ports sealed with heavy-duty metal blanking caps.
• Marine Anti-Rust Wax: External bare hub surfaces, sprocket mounting faces, and bolt threads coated with heavy marine anti-rust wax.
• Solid Structural Base Mounting: The drive unit is bolted down upright to high-density solid wood base skids to prevent tipping during transit.
• ISPM 15 Fumigation-Free Solid Plywood Box: Fully enclosed export crate banded with multiple high-tensile galvanized steel straps.

Sealed ports, protective anti-corrosion wax, and reinforced wooden crating

Step 7: Supported Global Logistics & Customs Documentation

Prompt logistics dispatch adapted for urgent machine-down emergencies and trade stock:

• Air Express (3–7 Days Door-to-Door): Handled via DHL Express, FedEx, or air cargo for rapid jobsite recovery.
• Sea Freight Consolidation: Economical LCL shipping for distributors stocking multiple units.
• Tariff-Ready Paperwork: Commercial invoice detailing official HS Code (8483.40 / 8412.29), packing lists, and Certificate of Origin (COO) upon request.
