IHI60 IHI65 IHI70 Final Drive Travel Motor | High-Torque Propulsion for IHI-Kato Excavators

The Final Drive and Travel Motor Assembly for the IHI60, IHI65, and IHI70 series is the heavy-duty propulsion heart of these 6 to 7.5-ton class excavators. Engineered for the mid-sized machine segment, this assembly integrates a high-pressure axial piston motor with a multi-stage planetary gearbox to deliver the superior tractive effort and synchronized tracking required for urban construction, utility trenching, and site development.

Precision Power for the Mid-Size Workhorse The IHI60, IHI65, and IHI70 (often rebranded under Kato Works) are legendary for their compact power and hydraulic balance. The final drive is the critical component that converts that balance into movement. Whether you are navigating a muddy residential job site or climbing a trailer, this assembly ensures your tracks have the synchronized torque to operate without "tracking drift."

In the 6-7 ton class, final drives are subjected to high rotational stress and frequent directional changes. Our premium units feature induction-hardened gears and high-capacity internal bearings. Replacing your worn-out drive with this precision-engineered assembly restores the machine's factory-standard breakout force and travel speed, bringing "new life" to your IHI fleet.

IHI machines are widely utilized in global markets, and our drives are optimized for these conditions:

• North America & Europe: Ideal for Rental Fleets and Utility Contractors. Our drives are built for high-duty cycles and are fully compatible with biological hydraulic fluids and standard North American pressure ratings.

• Japan & East Asia: Specifically tuned to match the precision "pilot-control" systems found in Japanese-spec IHI/Kato models, ensuring smooth, jerk-free travel.

• Southeast Asia & Oceania: Equipped with reinforced "Heavy-Duty" floating seals to prevent the ingress of abrasive tropical mud and coral dust, which are common in coastal infrastructure projects.

A mid-size final drive is an investment; protect it with these technical protocols:

• The Case Drain Warning: Before operating the new motor, you must ensure the case drain line is clear and the filter is replaced. A blocked case drain will cause an immediate pressure spike, blowing the shaft seal and destroying the motor.

• Gear Oil Maintenance: Change the planetary gearbox oil every 500 operating hours. For machines working in water or mud, check for a "milky" appearance frequently—this indicates water ingress that will quickly grind down the gear teeth.

• Sprocket Bolt Torque: These machines exert significant torque on the sprocket flange. Always use new bolts with a high-strength thread locker and torque to factory specifications.

• System Flushing: If the original motor failed catastrophically (with metal debris in the oil), a full hydraulic system flush is mandatory before installing the new unit.

Guangzhou Tieqi Construction Machinery Co., Ltd. (IRON CAVALRY) is strategically located in Guangzhou's Huangpu District, approximately an hour from Baiyun International Airport. We have been a dedicated specialist in engineering machinery hydraulics for nearly 15 years.

Driven by our core values of "Pragmatism and Progress," we are committed to delivering practical solutions and upholding our responsibilities. This principle-driven approach defines all our operations and client partnerships.

In China's excavator hydraulic assembly sector, our efficient execution and rigorous approach to manufacturing every product to meet over 95% of original performance specifications have built widespread trust. This has made us a destination for industry peers and clients seeking knowledge and reliable supply.

Our capability is backed by a ready inventory of over 500 assembly types, providing access to more than 6,000 different parts. Hydraulic pump, control valve, travel, and swing assemblies are our core products, with a distinct advantage in large mining excavator components and hard-to-find items.

Our 4,000-square-meter factory in Guangzhou is equipped for professional manufacturing, precision assembly, rigorous testing, and quality certification, ensuring reliable performance and timely delivery for every order.

For large items, we use sturdy plywood crates secured with metal fasteners for added stability. Inside, the products are cushioned with bubble wrap and secured with wooden braces, while special attention is given to protecting vulnerable parts. Externally, the crates are reinforced with high-strength PET plastic strapping and wrapped in highly waterproof black film.
