Aftermarket High Quality Integrated Final Drive Travel Motor Reducer 9149087 9149087EX for John Deere 200LC 230LC 230LCR Medium Excavator

1. OEM Part Number & Machine Compatibility
Original travel motor model: Hitachi HMGC35 two-speed integrated final drive (hydraulic travel motor + 3-stage planetary reduction gearbox)
John Deere OEM interchange part numbers: 9149087, 9149087EX
Fully compatible medium excavator models: John Deere 200LC, 230LC, 230LCR
9149087EX is the upgraded supersession version of base part 9149087; identical mounting flange bolt pattern, sprocket hub interface, hydraulic A/B feed & drain port layout and internal hydraulic calibration, fully cross-replaceable direct bolt-on aftermarket replacement without track frame or 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) + three-stage planetary reduction gear reducer
Dual motor displacement: 62 / 98 cm³/rev
Total gear reduction ratio: 42
Second Stage Specified High-Speed Travel Parameters
Rated working pressure (second stage): 34.3 MPa
Maximum relief pressure (second stage): 35.0 MPa
Rated operating speed (second stage): 2800 rpm
Corresponding rated input power (second stage): 52.6 kW
Max output climbing torque: 26800 N·m
Dual travel speed range: 26~46 rpm, perfectly matched to factory hydraulic system of 20–23 ton John Deere medium excavator platform
Mounting PCD, sprocket tooth size, oil port position strictly conform to John Deere OEM dimensional drawings
Gearbox & motor casing adopt high-strength ductile iron; internal pistons, valve plates, planetary gears, carrier and bearings use quenched wear-resistant alloy steel for long heavy-load service life

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 excavation; Second-stage high-speed mode for flat ground fast transfer
Built-in multi-disc spring-applied hydraulic release mechanical parking brake, stable holding performance on steep slopes to prevent track sliding
Three-stage planetary reduction gear set amplifies hydraulic motor torque to drive track sprocket, stable continuous power output under long digging and loading loads
Integrated built-in anti-cavitation valve and shock relief valve to absorb hydraulic pressure surges, effectively protect motor core components from hydraulic impact damage
Compact integrated final drive layout fits perfectly inside the track frame space of JD200LC / 230LC / 230LCR medium excavators
