Original Nabtesco GM21VA‑A Integrated Final Drive Travel Motor Assembly with Gearbox SA1143‑01060 SA7117‑30011 SA1143‑01112 for VOLVO EC140 EC140B Excavator

1. OEM Part Number & Machine Compatibility

Original travel motor model: Nabtesco GM21VA‑A two‑speed integrated final drive (hydraulic travel motor + 2‑stage planetary reduction gearbox)
Volvo OEM interchange part numbers: SA1143‑01060, SA7117‑30011, SA1143‑01112, VOE14524182, VOE14528729
Fully compatible excavator models: VOLVO EC140, EC140B
All listed part numbers are iterative supersession codes for the same complete assembly. Unified mounting flange bolt pattern, sprocket hub interface, hydraulic A/B feed & drain ports and internal hydraulic calibration. Genuine original unit supports direct bolt‑on replacement, no modification to track frame or hydraulic pipelines required.

2. Core Technical Specifications

Structure type: Two‑speed variable displacement hydraulic travel motor (Stage 1: Low Speed High Torque / Stage 2: High‑Speed Travel) + two‑stage planetary reduction gear reducer
Dual motor displacement: 44 / 79 cm³/rev
Total gear reduction ratio: 54

Second‑Stage High‑Speed Working Parameters

Rated working pressure: 32.0 MPa
Maximum relief pressure: 34.8 MPa
Rated operating speed: 2450 rpm
Rated input power: 43.5 kW
Max output climbing torque: 20600 N·m
Dual travel speed range: 28‑52 rpm, perfectly matched to factory hydraulic system for 14‑ton VOLVO EC140 / EC140B excavator platform
Mounting PCD, sprocket fit dimension and oil port layout strictly follow Volvo OEM drawing specifications
Motor and gearbox housing made of high‑strength ductile iron; internal pistons, valve plate, planetary gears, carrier and heavy‑duty bearings adopt quenched wear‑resistant alloy steel for general construction and rough‑site operations.

3. Internal Structure & Functional Introduction

Dual‑displacement travel motor offers two working modes: low‑speed high‑torque mode for slope climbing, muddy terrain and heavy digging; high‑speed mode for fast flat‑ground machine relocation.
Built‑in multi‑disc spring‑applied hydraulic‑release mechanical parking brake, prevents track sliding on inclined ground when travel control is released.
Two‑stage compact planetary gear set amplifies hydraulic torque to drive track sprocket, delivering stable continuous power output under heavy‑load conditions.
Integrated anti‑cavitation valve and built‑in shock relief valve absorb hydraulic pressure spikes during compound movements, protecting internal core components from impact damage.
Compact integrated layout perfectly fits undercarriage installation space of VOLVO EC140 and EC140B excavators.

4. Product Advantages

Genuine original Nabtesco complete assembly, 1:1 OEM dimension, plug‑and‑play installation without cutting or reworking hoses, track frame or mounting brackets.
Every original final drive passes full factory hydraulic bench test before shipment: two‑speed shift test, pressure stability test, internal leakage test and brake holding torque verification.
Full overhaul spare parts are available: floating seal, piston shoe assemblies, swash plate, valve plate, planetary gear sets, carrier, bearings and full seal repair kits for component‑level maintenance.
Multiple cross‑reference OEM numbers for EC140 / EC140B, simplify order processing, stock classification and inventory management for dealers and repair workshops.
Standard 12‑month full warranty for original unit, performance consistent with factory‑fitted travel motor assembly.

5. Packaging & Global Delivery Details

Oil ports and output spline shaft coated with anti‑rust grease and fitted with dust‑proof protective plugs.
Complete final drive wrapped with moisture‑proof plastic film and secured in export‑grade solid wooden crate to avoid collision and damp corrosion during sea or air long‑haul transit.
In‑stock original units can be dispatched within 3‑5 working days after order confirmation.
Multiple shipping options available: international air express, sea LCL bulk shipment, overland truck transport for global construction machinery markets.
