The Komatsu 708-1S-00940 Gerotor Hydraulic Motor. This pump is responsible for providing a stable and high-pressure hydraulic oil flow for the steering of the entire machine, the working device (bucket lifting and tilting), and the transmission system (if applicable). Its performance directly affects the operational efficiency and power response of the equipment.

This product is strictly manufactured and inspected in accordance with Komatsu's original factory standards to ensure perfect integration with the host equipment. It can restore the hydraulic performance of the equipment to its new condition and is a reliable choice for preventive maintenance, major overhauls or fault replacements.

1. Precise matching, ready to use: Specifically designed for the listed Komatsu models, the installation interface is precisely matched with the size, minimizing downtime to the greatest extent.
2. Strong and long-lasting power output: The optimized internal structure design ensures that it can provide continuous and stable flow and pressure even under high-load conditions, guaranteeing the equipment's powerful performance.
3. Outstanding durability and reliability: Made of high-strength alloy materials and advanced surface treatment processes, the core components (such as the cylinder block, distribution plate, and sliding shoe) have extremely high wear resistance and fatigue strength, extending the major overhaul cycle.
4. Efficient energy utilization: Precise manufacturing tolerances and optimized internal leakage control enhance volumetric efficiency, which helps to reduce engine load and fuel consumption.
5. Comprehensive quality assurance: Each pump undergoes strict performance tests (including pressure, flow, and noise tests) to ensure that all products leaving the factory are 100% qualified.

This product 708-1S-00940 is applicable to the following equipment:
Crawler tractor：D375A series
Wheel loader：WA380 Series,WA430 Series,WA450 Series,WA470 Series,WA480 Series

Important Note: There may be sub-models of the equipment in different markets. To ensure 100% compatibility, please check the model on the nameplate of your device before placing an order, or provide the part number on the old pump to confirm with us.

• Packaging method: Custom foam lining + high-strength pressure-resistant cartons/wooden crates are used to ensure zero damage during transportation.
• Shipping weight: Approximately 30-40 kilograms (including packaging).
• Delivery time: Usually in stock, it can be dispatched within 7 days.

Q1: Is this an original Komatsu part?

A1: We offer multiple options. You may choose genuine Komatsu parts (with original packaging) or high-quality alternatives (performance compliant, more cost-effective). Please specify your requirements when placing an order or during consultation.

Q2: Does purchasing this pump assembly include the seals and O-rings required for installation?

A2: As a complete pump assembly, it typically includes seals integrated directly with the pump body. However, we recommend simultaneously inspecting and replacing seals at pipe connections-often sold separately-to ensure leak-free installation.

Q3: What is the warranty period?

A3: We offer a 12-month warranty against non-human-induced quality issues, ensuring worry-free purchasing.

Q4: My machine is a WA470-5. Will this pump definitely work?

A4: According to Komatsu's official parts interchangeability documentation, part number 708-1S-00940 is confirmed compatible with the WA470-5. Compatibility is guaranteed as long as your machine's model number matches the listed specification exactly.

Genuine Product Guarantee: Transparent sourcing, zero tolerance for counterfeits.

Technical Support: Professional engineering team provides installation guidance and troubleshooting assistance.

Rapid Delivery: Deep partnerships with major logistics providers ensure swift, secure delivery to your doorstep.

Customer First: One-stop solutions from product selection to after-sales service-your trusted partner.
