This OEM part number is the factory original assembly code; unified mounting flange bolt pattern, sprocket hub interface, hydraulic A/B feed & drain port layout and internal hydraulic calibration. Genuine original unit supports direct bolt‑on replacement without modification to track frame or hydraulic pipelines.
Dual travel speed range: 28‑52 rpm, perfectly matched to factory hydraulic system for 13‑15 ton Komatsu PC135F / PC150‑1 excavator platform
Mounting PCD, sprocket fit dimension and oil port layout strictly follow Komatsu 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 matches the undercarriage installation space of Komatsu PC135F and PC150‑1 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.

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.
Factory OEM number 21K‑60‑00020 dedicated for PC135F / PC150‑1, 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.
