Original Nachi PHV‑300‑53B‑1S1‑8738B Integrated Final Drive Travel Motor Assembly with Gearbox 19031‑19900 for Takeuchi TB135 Mini Excavator
1. OEM Part Number & Machine Compatibility
Original travel motor model: Nachi PHV‑300‑53B‑1S1‑8738B two‑speed integrated final drive (hydraulic travel motor + 2‑stage planetary reduction gearbox)
Takeuchi OEM interchange part numbers: 19031‑19900, 19031‑20700, 19031‑25700, 19031‑27300
Fully compatible mini excavator model: Takeuchi TB135
All listed serial numbers are iterative supersession upgrade codes, unified mounting flange bolt pattern, sprocket hub interface, hydraulic A/B feed & drain port layout and factory hydraulic calibration; genuine original unit enables direct bolt‑on installation without track frame or hydraulic pipeline modification
2. Core Technical Specifications
Structure type: Two‑speed variable displacement hydraulic travel motor (Stage 1: Low Speed High Torque / Second Stage: High‑Speed Travel) + two‑stage planetary reduction gear reducer
Dual motor displacement: 32 / 51 cm³/rev
Total gear reduction ratio: 52
Second Stage Specified High‑Speed Travel Parameters
Rated working pressure (second stage): 24.0 MPa
Maximum relief pressure (second stage): 26.5 MPa
Rated operating speed (second stage): 2800 rpm
Corresponding rated input power (second stage): 21.2 kW
Max output climbing torque: 4350 N·m
Dual travel speed range: 32~58 rpm, perfectly matched to factory hydraulic system of 3.5‑ton Takeuchi TB135 compact excavator platform
Mounting PCD, sprocket tooth dimension, oil port position strictly comply with Takeuchi OEM dimensional drawings
Gearbox & motor housing adopt high‑strength ductile iron; internal pistons, valve plates, planetary gears, carrier and bearings use quenched wear‑resistant alloy steel for long‑term compact construction operation
3. Internal Structure & Functional Introduction
Dual‑displacement travel motor provides two working modes: Stage 1 low‑speed high torque for muddy ground, slope climbing and heavy digging; Second‑stage high‑speed mode for flat‑site fast machine transfer
Built‑in multi‑disc spring‑applied hydraulic release mechanical parking brake, stable holding performance on inclined terrain to prevent track sliding
Two‑stage compact planetary gear set amplifies hydraulic motor torque to drive track sprocket, delivering steady continuous power output under heavy‑load digging conditions
Integrated built‑in anti‑cavitation valve and shock relief valve absorb hydraulic pressure surges, effectively protecting internal core components from impact damage during compound actions
Compact integrated final drive layout fits perfectly within the limited track‑frame installation space of Takeuchi TB135 mini excavator
4. Product Advantages
Genuine original Nachi complete assembly, 1:1 OEM casting dimensions, plug‑and‑play fitment with no cutting or re‑working of hydraulic hoses, track frame or mounting brackets
Every original final drive passes full factory hydraulic bench inspection before delivery, covering two‑speed switching test, pressure stability, internal leakage test and brake holding torque verification
Full range overhaul spare parts available: floating seal, piston shoe assemblies, swash plate, valve plate, planetary gear sets, carrier, bearings and complete seal repair kits for component‑level maintenance
Multiple interchangeable Takeuchi OEM part numbers dedicated for TB135, streamlining spare‑part ordering, stock classification and inventory management for dealers and repair workshops
Standard 12‑month full warranty for original unit, consistent performance matching factory‑installed stock travel motor assembly
5. Packaging & Global Delivery Details
Motor oil ports and output spline shaft coated with anti‑rust grease and sealed with dust‑proof protective plugs
Entire final drive wrapped with moisture‑proof plastic film and secured inside export‑grade solid wooden crate to prevent collision and moisture corrosion during long‑distance sea or air transit
In‑stock original units can be dispatched within 3‑5 working days after order confirmation
Multiple global shipping solutions available: international air express, sea LCL bulk shipment, overland truck transport for global compact machinery markets
6. FAQ
Q: Are 19031‑19900, 19031‑20700, 19031‑25700, 19031‑27300 mutually interchangeable?
A: Yes, these are iterative replacement codes for the same Nachi PHV‑300‑53B‑1S1‑8738B final drive assembly, fully cross‑replaceable for Takeuchi TB135.
Q: Can this original final drive install directly on Takeuchi TB135?
A: Yes, unified OEM mounting dimensions and factory‑calibrated hydraulic settings support direct bolt‑on fitting without extra adjustment or modification work.
Q: What is the relation between PHV‑300‑53B‑1S1‑8738B and Takeuchi OEM numbers?
A: PHV‑300‑53B‑1S1‑8738B is Nachi’s original travel motor model designation; 19031‑19900, 19031‑20700, 19031‑25700 and 19031‑27300 are Takeuchi‑assigned OEM part numbers for this complete final‑drive assembly.
Q: Are individual repair spare parts available for this travel motor?
A: Matching full overhaul seal kits, piston shoe assemblies, valve plates, swash plates, planetary gear carriers and floating seal spare parts are all available for partial overhaul and single‑component replacement work.
