Kawasaki K3V112DTP-YT6K YN10V00036F1 hydraulic pump for Kobelco SK200-8 midi 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.

Product Brief
This K3V112DTP‑YT6K tandem axial piston pump serves as the core hydraulic power source for Kobelco SK200‑8 20‑ton excavator. It transforms engine rotary power into adjustable high‑pressure hydraulic flow to sustain heavy‑load site tasks including rock digging, material loading, trench excavation and simultaneous multi‑cylinder compound movements. This aftermarket replacement assembly is widely adopted by overseas equipment repair workshops, rental fleet managers and cross‑border spare‑part merchants for failed original pump swap and full hydraulic system overhaul.
Under continuous high‑intensity site operation with frequent shock and variable load, the original pump will incur cylinder block scuffing, piston shoe wear and valve plate galling. Typical fault symptoms cover insufficient digging output, slow arm and boom responsiveness, weakened traveling performance, persistently rising hydraulic oil temperature, abnormal pump vibration noise and sharp pressure drop under heavy digging condition. Sudden pump malfunction will halt construction progress and generate unplanned emergency repair expenditure for project operators.
Our aftermarket pump strictly adheres to OEM dimensional criteria for mounting flange, input shaft spline, regulator installation position and system pressure calibration. No cutting, drilling or auxiliary adapter modification is required during on‑site fitting, which effectively cuts machine downtime. As an economical alternative to high‑cost original pumps with long lead‑time, this unit delivers dependable hydraulic performance and satisfies bulk procurement needs for global Kobelco excavator spare‑part suppliers.
Unique Product Competitive Advantages
1. High‑precision fit matching SK200‑8 original hydraulic assembly
Produced against original technical drawing standards, this main pump retains identical shaft spline parameters, oil port layout and regulator assembly dimension. Precisely processed friction assemblies restrain internal leakage after assembly. No secondary machining work is necessary for field installation, allowing maintenance technicians to complete pump replacement efficiently.
2. Reinforced friction‑pair craft for long‑duration heavy‑duty construction scenarios
Many low‑cost substitute pumps experience rapid performance degradation under repeated compound digging and swinging load. Our core internal components adopt carburizing quenching and multi‑step fine‑grinding process to boost wear‑resisting performance under alternating shock load, helping fleet owners reduce pump replacement frequency for heavily‑operated SK200‑8 machines.
3. Full‑range bench validation before shipment to avoid unexpected field breakdown
Each finished hydraulic pump undergoes pressure endurance test, flow calibration and sealing leakage inspection on dedicated hydraulic test bench prior to packing. Defective products are eliminated inside factory, easing re‑work burden for maintenance teams and preventing unplanned job‑site downtime losses.
4. Budget‑friendly aftermarket solution for medium excavator maintenance cost control
Genuine OEM pumps for SK200‑8 come with high purchasing expense and extended delivery cycle. Our factory‑direct aftermarket pump delivers reliable operating stability and full‑system compatibility, cutting annual overhaul cost for customers managing multiple Kobelco excavator fleets.
5. Flexible global logistics options for wholesale importers
In‑stock items support fast dispatch after payment confirmation. Air freight is available for urgent breakdown repair orders; consolidated sea freight and full‑container solutions offer cost‑saving choices for long‑term bulk purchasers.
Factory Production Strength
Our manufacturing workshop focuses on R&D and mass‑production of aftermarket hydraulic main pumps, travel gearboxes and swing motors covering mainstream Japanese excavator series. We possess complete production workflows: alloy‑steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench test. Dedicated simulation equipment replicates real‑site variable heavy‑load working state of 20‑ton excavators to verify component durability. Our hydraulic spare parts are exported to multiple overseas markets and maintain long‑term stable partnerships with global construction‑machinery spare‑part wholesalers.
Frequently Asked Customer Questions
Q1: Can this K3V112DTP‑YT6K main pump fit other Kobelco excavator models besides SK200‑8?
A1: Cross‑model installation is not recommended. Different main pumps differ in shaft spline, regulator parameters and pressure calibration values. Please double‑check machine model and original part number before submitting orders.
Q2: What hydraulic defects can this main pump solve?
A2: It repairs failures caused by worn pistons, scratched valve plate and damaged inner assemblies: weak digging force, sluggish cylinder movement, over‑heated hydraulic oil, internal leakage and abnormal vibration or knocking noise generated by main pump.
Q3: Can I obtain volume‑based discount for large‑quantity orders?
A3: Yes, tiered preferential price is provided according to purchase quantity. Full‑container sea shipment can be arranged to reduce overall logistics expenditure.
Q4: What packaging will be used for long‑distance overseas transportation?
A4: Anti‑rust grease is evenly coated on all metal surfaces. The whole pump is wrapped with waterproof shock‑resistant PE film, then secured inside reinforced export‑grade plywood case, preventing collision deformation and moisture corrosion during long‑haul transit.
