708-1U-00163 hydraulic pump for Komatsu WB93R-8 excavator
If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

1. Product Overview
The Komatsu Hydraulic Piston Pump is an axial piston variable displacement unit specifically engineered for the WB93R-8 series backhoe loader. This pump is a direct replacement for OEM part number 708-1U-00163. It is designed to integrate with Komatsu’s advanced "SyncroSystem" hydraulic logic, which matches the pump's output to the operator’s demand for high-speed travel or high-torque digging.

3. Key Engineering Advantages
Optimized Flow Sharing: Specifically calibrated to handle the dual functionality of a backhoe loader. The pump ensures that hydraulic flow is distributed evenly between the steering, loader, and backhoe circuits, preventing performance drops during multi-function tasks.
Precision Load Sensing: The variable swashplate design adjusts instantly to joystick input, providing high precision for delicate grading and high speed for loading cycles.
Thermal Efficiency: Internal porting is designed to reduce friction and turbulence, keeping hydraulic oil temperatures low during high-duty cycles like continuous trenching.
Durable Construction: Features high-strength alloy cylinder blocks and induction-hardened pistons to withstand the intense pressure spikes common in backhoe and breaker applications.
