Our mechanics accurately identify faults in advanced power hydraulics from manufacturers such as Bosch Rexroth, Sauer Danfoss, or Parker, as well as efficiently restore the rated performance of CAT, Volvo, or Cummins power units. We ensure that your crushing and screening equipment minimizes downtime and returns immediately to continuous operation in the mine or recycling plant. We fully understand the operational challenges and structural specifics of jaw and cone crushers, as well as mobile and stationary screeners. Our key advantage is the harmonious combination of many years of practical experience with modern research and technological facilities. Every remanufactured piston pump, hydraulic motor, or control valve goes to our proprietary hydraulic test bench, where it undergoes demanding pressure tests. This guarantees the absence of hidden defects and gives you confidence that the equipment will easily handle extreme operational loads. No more reduced efficiency and unstable operation ### Internal Combustion Engine Rebuilding Have you noticed disturbing smoke, loss of compression, excessive oil consumption, or difficulties in starting your Metso crusher or screener? At WIBAKO, we don't settle for temporary fixes. Our specialized combustion drive department performs full, comprehensive overhauls of units installed in machinery of this brand. We restore the original efficiency and factory torque of engines from manufacturers such as Caterpillar, Cummins, Volvo, or Perkins. We care about every parameter - from digital dimensional verification of the block to precise system tuning of fuel injection. An engine delivered to the workshop is completely disassembled, thoroughly cleaned, and subjected to micrometric measurements of working component wear. We plan and regenerate cylinder heads, machine crankshafts, install brand-new repair kits, and verify the timing and fuel supply systems. Certainty of parameters and continuity of operation after overhaul ### WIBAKO Stationary Engine Dynamometer We conduct test-bench load trials on a stationary engine dynamometer capable of handling units with power up to 500 HP. Instead of estimates, we offer hard measurement data - we verify and calibrate CAT, Cummins, or Volvo engines before reassembly into the Metso machine, eliminating the risk of another downtime. The crushing and screening process, which generates immense power, requires a stable drive. The final stage of our repair is a long-term test under variable and maximum operating loads. On the dynamometer, we recreate the real operating environment of Metso equipment, monitoring real-time parameters such as: **Actual torque and net power output** **Pressure and temperature dynamics in the main oil gallery and cooling system** **Smoke density level and exhaust gas temperature** **Fuel consumption and complete tightness of pressure connections** ### Peace of mind and safety for your facility ### 12 months of warranty protection We are confident in the quality of our work, which is why every combustion engine after a complete rebuild is covered by a transparent 12-month warranty. We protect your business from the constant risk of downtime, providing full care for Caterpillar, Cummins, Volvo, or Perkins engines operating in Metso crushers and screeners. When to carry out drive diagnostics? ### Symptoms of Engine Wear in Metso Crushers and Screeners Metso aggregate processing machinery operates in dusty environments and under continuous, extreme loads. Ignoring signals indicating drive wear inevitably leads to costly production line shutdowns. **Pay attention to the following symptoms:** **Altered exhaust color under load -** dark, thick smoke usually signals issues with boosting or injection equipment. A bluish tint indicates engine oil burning, while white clouds inform of coolant leaks. **Sudden drop in RPM during material feed -** the machine visibly loses vigor and "chokes" when heavy material is fed into the crushing chamber or onto the screen deck. **Difficulty starting the drive -** hard cold starting after standing idle, or difficulties restarting a warm engine during the workday. **Irregular rhythm and knocking sounds -** fluctuating idle speed and any metallic sounds coming from the engine compartment. **High crankcase pressure -** visible smoke or oil blow-by coming through the dipstick or oil filler cap. **Unexplained loss of operating fluids -** regular drop in oil or coolant levels with no signs of external leaks. Precise remanufacturing of high-pressure systems ### Specialized Fluid Power / Hydraulics Service At WIBAKO, there is a separate, specialized section of mechanics dedicated exclusively to power hydraulic systems. Our team is thoroughly familiar with the design and load characteristics of piston pumps, hydraulic motors, and control valves fitted in Metso machinery by manufacturers such as Bosch Rexroth, Sauer Danfoss, or Parker. A component handed over for repair is completely disassembled, washed, and measured with micron precision for wear on cylinders, pistons, and valve plates. Our extensive in-house stock of components allows for efficient replacement of rotary groups, seals, and bearings. As a result, we have reduced repair times to a minimum, offering quality equivalent to brand-new components at significantly lower costs. Elimination of fault risk before reassembly ### Hydraulic Test Bench Testing Accurate diagnosis and rigorous assembly control form the foundation of efficient hydraulics service. We have advanced testing stations and a dedicated hydraulic test bench where we verify the parameters of pumps, hydraulic motors, and control valves prior to their final installation on the machine. We measure flow rate, internal leakage, and working pressure at maximum load in real time. This procedure allows us to detect any execution irregularities before the component reaches the Metso crusher or screener, ensuring full reliability in the field. ### How to avoid damage to the entire system? ### Symptoms of Power Hydraulics Problems The hydraulic system in crushers and screeners is responsible for driving conveyors, adjusting the crusher gap, driving screen decks, and powering the tracked undercarriage. Prompt recognition of malfunctions prevents contamination of the entire system with metal particles. **Main symptoms of hydraulic faults:** **Drop in performance after the machine warms up -** the system works correctly for the first dozen or so minutes, after which, as the oil temperature rises, there is a noticeable drop in power and reaction speed. **Issues with gap adjustment or conveyor drives -** the crusher has difficulty regulating chamber geometry or belts stall under light loads, accompanied by a loud whistling sound from relief valves. **Uneven or weak crawler movement -** the machine pulls to one side while moving around the site or completely loses drive on one of the hydraulic motors. **Loud, harsh main pump operation -** a metallic sound coming from the hydraulic pump, often a consequence of cavitation or physical grinding of rotary components. **Rapid oil temperature increase -** working fluid quickly reaches critical values, destroying seals and accelerating the degradation of lubricating properties. **Presence of metal shavings in filter housings -** the appearance of metal filings on filter cartridges is a warning signal requiring an immediate machine shutdown. Fast repairs directly at your facility ### WIBAKO Mobile Service for Machinery Equipment failures on the production line generate immediate losses, which is why our field service team is ready for immediate intervention directly at the Metso crusher or screener operating site. Our specialists have mobile diagnostic points equipped with portable flow meters, high-pressure gauges, and tools for fault finding in automation and hydraulics. A significant portion of breakdowns is resolved on the spot at the service location. Thanks to the constant integration of mobile service with the spare parts warehouse, the service technician collects the necessary components immediately before departure, keeping repair time to an absolute minimum.
