Bobcat Service

### Bobcat Machines: Specific Characteristics and Operating Challenges

Compact construction equipment from Bobcat – including iconic skid-steer loaders, compact track loaders and mini excavators – forms the foundation of earthmoving, municipal and road works around the world. It is characterized by exceptional maneuverability, high power density and tightly integrated hydraulic systems. This design, however, imposes strict requirements on the failure-free operation of individual components.

Continuous operation under extreme loads in dusty environments promotes failures. The greatest risk for a business is unplanned machine downtime, which generates significant costs and delays in contract execution. Difficult operating conditions have the fastest impact on the condition of hydrostatic systems and drive units.

We provide comprehensive technical support – both stationary, carried out at our central workshop, and mobile, directly at the Customer's location. Our team of engineers and service technicians accurately diagnoses faults, eliminates their causes and restores Bobcat machines to full factory performance.

Why WIBAKO?

### Engineering Facilities and Our Experience

Working with our company is a guarantee of the highest quality and technical standards, which we have built through decades of market experience.

Over 30 years of experience: For more than three decades, WIBAKO has specialized in the regeneration, servicing and repair of heavy and compact construction equipment.

**Two Specialized Departments:**

**Hydraulics Department:** Our experts are dedicated exclusively to the diagnosis and regeneration of hydraulic pumps, travel motors, hydraulic control valves and cylinders.

**Diesel Engines Department:** Our team of engineers and mechanics carries out comprehensive major overhauls of drive units.

**Modern Diagnostic Facilities:**

**Hydraulic System Test Benches:** After every regeneration, we perform pressure tests and measure flow efficiency under load.

**Stationary Engine Dynamometer:** After major overhauls, engines undergo a complete running-in process and verification of power and torque parameters on our stationary load dynamometer before the equipment is returned to the Customer.

### Why WIBAKO?

### Bobcat Hydraulic System Repair and Regeneration

Hydrostatic drive systems in Bobcat machines require absolute precision in operation. Our team of experts carries out the complete regeneration process of hydraulic system components, including grinding of control valves, replacement of rotating groups in piston pumps, regeneration of cylinder blocks, replacement of pistons and technical seals.

**In Bobcat machines, we regenerate and diagnose, among others:**

Variable displacement piston pumps (including Rexroth, Sauer Danfoss and Eaton travel drive systems)

Travel hydraulic motors and planetary final drives of hydraulic motors

Swing motors and main pumps in mini excavators

Proportional hydraulic control valves and relief valves

Bobcat Service

### Major Overhauls of Diesel Engines in Bobcat Machines

At WIBAKO, we carry out comprehensive rebuilds of drive units used in Bobcat machines. Each overhaul includes block alignment, grinding or replacement of the crankshaft, replacement of cylinder liners, pistons, rings and bearings, as well as complete cylinder head regeneration. Common Rail fuel systems and injection pumps undergo precise calibration.

**We service and regenerate engines from brands used in Bobcat equipment:**

**Kubota:** V2203, V2403, V2607, V3307, D1105, D1803 series,

**Bobcat (Doosan):** D18, D24, D34 series (including systems with Common Rail and DPF),

**Deutz:** TD 2.9 L4, D2011, BF4M2011 series,

**Perkins:** 404D, 404F, 104-22 series.

Service throughout Poland

### Mobile Machine Service with On-Site Assistance

Responding to the needs of dynamic construction sites, our WIBAKO Mobile Service travels directly to the breakdown location. Our service vehicles are equipped with specialized diagnostic tools, portable flow meters, pressure testers and equipment for crimping hydraulic hoses. Our mobile team performs computer diagnostics, resolves minor hydraulic and electrical faults, and in the case of major failures, dismantles components and transports them to our central workshop.

### When to Act?

### Symptoms of Hydraulic System Failure in Bobcat Machines

Due to their compact design and high operating pressures, hydrostatic systems in Bobcat machines produce clear warning signs before complete seizure. Early intervention helps prevent costly metal debris from spreading throughout the entire system.

**The most common symptoms of hydraulic system failure include:**

**Loss of Power Under Load (Loud Pump Operation):** The machine loses lifting or pushing force as the hydraulic oil temperature rises, accompanied by characteristic whining or loud whistling from the hydrostatic pump.

**Uneven Travel or Loss of Steering:** In skid-steer loaders, the machine pulling to one side, slow response from one of the control systems or complete loss of drive on one side indicates wear of the piston pump or travel hydraulic motor.

**Hydraulic Oil Overheating:** A rapid increase in operating fluid temperature indicates internal leakage in the hydraulic control valve, relief valves or worn rotating groups in the pumps.

**Oil Foaming and Air Bubbles in the Reservoir:** Air entering the system is most often caused by leaks on the pump suction side or damaged shaft seals.

**Jerking and Delayed Attachment Response:** Cylinder vibrations and jerky operation of the loader or mini excavator boom indicate a drop in pilot control pressure or damage to proportional valves.

Do Not Ignore the Symptoms

### Symptoms of Engine Failure in Bobcat Machines

Drive units from Kubota, Doosan/Bobcat, Deutz and Perkins operating under demanding construction conditions give clear signals indicating the need for diagnostics or a major overhaul. Key symptoms of engine failure include:

**Unusual Exhaust Smoke Color:**

**Blue smoke:** Indicates engine oil burning due to worn piston rings, cylinder liners or valve stem seals.

**Black smoke:** Indicates incomplete fuel combustion caused by damaged Common Rail injectors, an injection pump or turbocharger problems.

**White smoke:** Indicates coolant entering the combustion chambers, for example due to a damaged head gasket or cracked cylinder head.

**Cold and Hot Starting Difficulties:** An inefficient injection system or reduced cylinder compression prevents the engine from starting properly.

**Metallic Knocking and Block Noises:** Knocking that intensifies under load often indicates worn connecting rod bearings, main bearings or excessive clearance at the piston pins.

**Blow-by into the Oil Sump and Oil Leaks Around the Filler Cap:** Excessive crankcase pressure and oil being forced out through the breather indicate critical wear of the piston-cylinder system.

**Low Oil Pressure and Overheating:** An oil pressure warning light coming on at idle with the engine warmed up requires immediate machine shutdown and service intervention.

### Wie wird ein Bobcat-Motor auf Ihrem stationären Prüfstand unter Last getestet?

Nach Abschluss der Generalüberholung montieren wir den Motor auf unserem Prüfstand. Die Einheit wird an das Messsystem angeschlossen, wo zunächst ein Einlaufvorgang durchgeführt wird. Anschließend erhöhen wir die Belastung schrittweise auf höhere Lastbereiche. Dabei messen wir den Öldruck, die Temperatur, die abgegebene Leistung, das Drehmoment sowie die Dichtheit der Systeme. Erst ein erfolgreiches Testergebnis berechtigt zur Abholung des Motors durch den Kunden.

### Welche in Bobcat-Maschinen eingesetzten Motorenmarken werden von Ihrem Service betreut?

Unser Service bietet umfassende Reparaturen für alle Motoren, die in Bobcat-Maschinen eingesetzt werden. Dazu gehören vor allem Kubota-Motoren, originale Bobcat/Doosan-Motoren (D18, D24, D34) sowie Motoren der Marken Deutz und Perkins.

### Ist es möglich, eine ausgebaute Pumpe oder einen Motor per Versand an den WIBAKO-Service zu senden?

Ja, wir betreuen Kunden in ganz Polen und im Ausland im Door-to-Door-System. Das ausgebaute Bauteil, beispielsweise eine Hydraulikpumpe, ein Hydromotor oder ein Dieselmotor, kann sicher auf einer Palette verpackt und an unseren Standort in Juszczyn geschickt werden. Nach der Diagnose und Kostenschätzung führen wir die Regeneration durch und senden das Bauteil anschließend montagefertig zurück.
