Service, diagnostics, and reconditioning of Takeuchi mini excavators, wheeled excavators, and track loaders

Takeuchi Service

At WIBAKO, we effectively diagnose and repair the entire range of Japanese construction equipment from Takeuchi. We eliminate failures of multi-piston pumps from Nachi, Kayaba (KYB), Uchida Rexroth, and recondition internal combustion engines from Yanmar and Kubota. We offer rapid mobile service directly at the construction site as well as advanced component reconditioning in our workshop, restoring Takeuchi machines to full operational efficiency.

 

When is it Time to Intervene?

Symptoms of Hydraulic Failure in Takeuchi Machinery

Japanese power hydraulics in Takeuchi machines are renowned for unmatched precision and smooth control. A noticeable drop in main pump efficiency, leaks from the swivel joint, or slow attachment operation are the first warning signs before a costly breakdown.

Here are the key symptoms indicating the need for diagnostics or reconditioning:

Weakening and slowing down of movements after the oil heats up: When a cold mini excavator (e.g., Takeuchi TB219 or TB225) works dynamically, but after several dozen minutes (once the oil reaches high temperatures) begins to slow down drastically, a loss of internal tightness in the main pump or main control valve is occurring.

Lack of power and dynamic drive, and pulling to one side: A Takeuchi TL10V2 track loader or TB260 excavator struggles to climb inclines or strays off its path, signaling wear in the travel motor or planetary gearbox.

Jerking and lack of precision in joystick control: Damage to the pilot system or proportional valves prevents precise ground grading.

Unnatural noise, grinding, or metal filings in the filter: Cavitation and noisy operation of the Nachi / KYB piston pump are direct symptoms of rotating elements seizing – immediate reaction prevents contamination of the entire system.

 

Professional Reconditioning

Specialized Team for Takeuchi Power Hydraulics

Our dedicated team of fluid power engineers perfectly knows the specifics of Japanese systems with variable displacement pumping controlled by a Load Sensing signal. At the WIBAKO workshop in Kojszówka, we recondition piston and gear pumps, travel motors, swing motors, and multi-section control valves for mini excavators Takeuchi TB016, TB125, TB216, TB230, compact excavators TB250, TB280FR, TB290, and wheeled excavators TB175W, TB295W. Instead of costly replacing entire subassemblies with new ones, we precisely replace rotary groups, valve plates, and pistons, restoring factory operating pressures.

 

Guarantee that hydraulics won't fail

Hydraulic Test Rig Testing

At WIBAKO, we eliminate guesswork and the risk of surprises on the job site. We have a specialized, stationary hydraulic test rig. Every KYB, Nachi, or Rexroth pump leaving our workshop first goes to the test bench, where we simulate extreme operating conditions at pressures up to 350 bar and an oil temperature of 70°C. We test the response accuracy of power regulators and the stability of operating pressures, issuing a full technological protocol.

No More Smoke and Power Loss

Internal Combustion Engine Overhauls

Japanese diesel engines from brands like Yanmar (e.g., 3TNV76, 4TNV88, 4TNV98 series) and Kubota (e.g., D1105, V2403, V3307) are the hearts of Takeuchi machines. When starting difficulties, knocking, or smoking under load appear, WIBAKO experts perform professional complete overhauls. We restore factory block fits, align crankshafts, replace sleeves and pistons, and precisely recondition Common Rail injection systems or injection pumps. Every unit regains factory torque and load response dynamics.

Warning Signs

When Does Your Takeuchi Engine Require an Overhaul?

Unusual exhaust smoke: Black smoke under load signals a failure of the injection system or turbocharger, while blue/white smoke indicates burning engine oil or coolant.

Power drop and machine "stalling": Lack of dynamics during simultaneous travel and attachment lifting heralds a drop in cylinder compression.

Excessive pressure and blow-by: Smoke from the breather or oil filler cap indicates wear of piston rings and cylinder walls.

Warm starting problems: Difficulties restarting after the machine heats up.

 

Under Load Testing

In-House Engine Dynamometer up to 500 HP

A reconditioned Yanmar or Kubota engine from a Takeuchi TB290 excavator or TL12 loader does not go blindly to the job site. At our service center in Kojszówka, it undergoes a break-in process on a stationary engine dynamometer. Under controlled conditions, we load the unit up to 100% rated power, checking oil pressure, cooling tightness, turbine efficiency, and Common Rail exhaust parameters.

 

Fast Diagnostics and On-Site Repair

Mobile Takeuchi Service

We fully understand that transporting a machine to a stationary workshop generates costs and delays. That is why WIBAKO mobile service vehicles are equipped with computer diagnostic equipment and digital pressure gauges for hydraulic pressure measurements. Mobile mechanics reach the Takeuchi machine directly at the job site, resolving electrical, valve, cylinder, or engine accessory faults on the spot. In the case of more severe damage, we safely disassemble the component and transport it to our workshop.

 

Instant Access to Parts

WIBAKO's Own Warehouse

Thanks to extensive warehouse facilities at WIBAKO, you don't wait weeks for deliveries from Japan. We stock a wide range of brand-new, reconditioned, and used parts for Takeuchi excavators and loaders: from complete seal kits, through pistons and plates for Nachi/KYB pumps, to swivel joint seals and Yanmar/Kubota engine parts.

 

 

Which combustion engines installed in Takeuchi machines do you repair?

We specialize in major overhauls and routine repairs of diesel engines from Yanmar (e.g., 3TNV70, 3TNV82A, 4TNV88, 4TNV98), Kubota (e.g., D902, D1105, V2403, V3307), and Deutz (e.g., TCD 3.6) mounted in wheeled machinery.

Do you perform load testing after remanufacturing a hydraulic pump or an engine?

Yes! We have our own stationary hydraulic test bench and an engine dynamometer (up to 500 HP) at our center in Kojszówka. Every remanufactured component (e.g., Nachi, Kayaba, Bosch Rexroth pumps or Yanmar/Kubota engines) undergoes testing under full working pressure. Upon the customer's request, we provide a technical report with the reconditioned unit.

Do you offer a mobile service with on-site visits to construction sites?

Yes, we have a fleet of WIBAKO mobile service vehicles equipped with advanced diagnostic tools and pressure gauges. Our technicians travel directly to the machine in the field, diagnose faults on-site, and fix most breakdowns without the need to transport the entire excavator.
