Hitachi EX200-5 Final Drive Travel Motor Assembly – Remanufactured to Factory Operating Standards

Note: The application information provided is for reference only. Please confirm the part number and compare it with the old component before purchasing. If you have any questions, please feel free to contact us.
It is worth choosing a product that features stable performance, high reliability, easy installation, and quick response.

The final drive travel motor is the component that converts hydraulic power into the torque needed to drive your excavator’s tracks. When this unit fails, the machine becomes completely immobile – a 20‑tonne obstruction that requires expensive recovery equipment just to get it to a repair location. A properly remanufactured final drive restores your EX200‑5 to full productivity for a fraction of the cost of a new OEM unit.

1. Key Features & Benefits

• Complete travel motor assembly – An integrated unit that combines a high‑torque axial piston hydraulic motor with a multi‑stage planetary gearbox and a spring‑applied parking brake, all in a single housing for direct bolt‑on replacement.

• High load‑bearing capacity – Engineered to handle the full operating weight of a 20‑tonne class excavator, providing the tractive force needed for demanding digging, steep slope climbing, and pushing through heavy material.

• Two‑speed travel capability – Factory‑spec two‑speed shifting allows the operator to select high‑speed travel for moving around the job site or low‑speed, high‑torque crawling for tough digging and climbing operations. The motor responds instantly to operator commands, maintaining the machine’s original responsiveness.

• HMGF series design – Standard travel motor of the EX200/ZX200 series, featuring an inclined cylinder block axial piston design that delivers high volumetric efficiency, low internal leakage, and reliable performance under continuous heavy loads.

• Integrated spring‑applied parking brake – Built‑in wet multi‑disc brake engages automatically when travel controls return to neutral, holding the machine securely on slopes. The brake releases instantly when a travel command is given, ensuring immediate response without drift.

• Dyno‑tested and ready to install – Each unit is fully disassembled, cleaned, crack‑inspected, rebuilt with new bearings, seals, and O‑rings, then run on a hydraulic test stand to verify operating pressure, smooth gear engagement, and no internal leakage before being released for shipment.

• Pre‑shipment visual verification – Detailed high‑resolution photographs are sent to you for approval before packing. You see the actual unit you are receiving – mounting flange, splines, port threads, and general condition – and approve shipment. No blind shipments, no surprises.

• Fast delivery – 5–8 working days lead time from our Guangzhou warehouse, with monthly supply capacity of 300 units.

Compatible models: Hitachi EX200‑5, EX200‑2, EX200‑3, EX210H‑5, EX220‑5, and ZX200 series. Cross‑references include OEM part numbers 9091681, 9146471, 9149087, 9233692, 9133918, 9261222, 9119377, 9124825 and 9148909. The motor type is a two‑speed axial piston travel motor with a displacement of 175 / 94.6 cc/rev (high / low speed). Maximum working pressure is 32.6 MPa (approx. 4,730 psi), maximum torque output reaches 65,000 Nm, and the gear reduction ratio is 48.1:1. The assembly weighs approximately 330 kg and requires SAE 90 or 80W‑90 gear oil (API GL‑4 or GL‑5) in the planetary side.

2. Applications

The Hitachi EX200‑5 with the HMGF series final drive travel motor has proven itself across decades of use in heavy industries where reliable track mobility is non‑negotiable.

• Heavy construction & infrastructure projects – Highway construction, dam building, bridge foundation work, and large‑scale site preparation all demand that the excavator moves reliably across unimproved terrain. A final drive failure in the middle of a highway cut stops production completely – the machine cannot move itself to a repair location, and towing a 20‑tonne excavator requires specialised heavy recovery equipment. A remanufactured final drive eliminates the guesswork of used components and restores OEM driveline integrity at a fraction of the cost of new.

• Mining & quarry operations – EX200‑5 excavators are used in open‑pit mines, aggregate quarries, and material handling operations where abrasive dust, extreme shock loads, and long continuous shifts are the norm. The HMGF series final drive’s high‑strength cast iron construction and premium duo‑cone floating seals are specifically designed to keep contaminants out of the planetary gearbox – fine dust would otherwise turn gear oil into grinding paste. For mine sites with limited service support, keeping a remanufactured final drive on the shelf transforms a week‑long immobilisation into a one‑day repair.

• Demolition & scrap processing – Working in demolition and metal recycling environments subjects the final drive to intense vibration, sharp metal debris, and repeated hard impacts against the undercarriage. The planetary gearing is designed to absorb these extreme shocks without internal damage. When the original unit reaches end‑of‑life, a remanufactured replacement delivers the same durability as new at a cost that makes proactive replacement economically viable.

• Forestry & land clearing – Steep slopes, soft ground, fallen timber, and hidden obstacles are routine in forestry applications. The final drive’s two‑speed capability allows the operator to switch between high‑speed site travel and low‑speed, high‑torque crawling for climbing slopes or pulling through mud. The integrated spring‑applied parking brake holds the machine securely on steep inclines, even with a loaded bucket.

• Equipment rental fleet maintenance – Rental machines see heavier use than privately owned equipment because multiple operators with varying driving habits cycle through them. Final drives on rental EX200‑5 units are high‑wear components. A failure mid‑rental creates costly recovery logistics, lost revenue, and damaged customer relationships. A remanufactured final drive provides a fresh start at a cost that makes proactive replacement before failure a financially sound decision.

• Aftermarket drivetrain rebuilds & overhauls – When overhauling an EX200‑5’s powertrain, installing a remanufactured final drive alongside new undercarriage components (sprockets, track chains, rollers) ensures that the weakest link in the track drive is eliminated. This is standard practice for fleets that want to extend machine life beyond 15,000 service hours.

Critical installation tip for the EX200‑5 final drive: The case drain line is the single most common installation point of failure. If the case drain line is blocked, kinked, or connected incorrectly, pressure will build inside the motor housing and blow the shaft seal instantly on first operation. Before starting the engine, verify that the case drain line is clear, unrestricted, and properly routed back to the tank. Also ensure the planetary gearbox side is filled with the correct gear oil (SAE 90 or 80W‑90, API GL‑4 or GL‑5). Do not overfill – excessive gear oil creates internal pressure that can force oil past the duo‑cone floating seals. After installation, cycle the travel controls at low idle several times to bleed air from the brake release circuit – the machine may not move initially until the system is purged.

The final drive travel motor is the mechanical nerve centre of your EX200‑5’s mobility. When it is healthy, you do not think about it. When it fails, nothing else matters. A remanufactured unit from Hongtengda Parts gets your 20‑tonne excavator back on the job – not next week, but now.
