Screening and Crushing Equipment Service

Professional Powerscreen Machine Repair

Powerscreen equipment operates in extreme conditions: gravel pits, quarries, and recycling sites, where dust, heavy loads, and continuous operation test the durability of every component. At WIBAKO, we offer comprehensive technical support for the full range of machines from this brand – from mobile screeners of the Warrior or Chieftain series, to jaw, cone, and impact crushers from the Pegson, Premiertrak, or Trakpactor series.

We fully understand that in the mining and demolition industries, unplanned downtime of a processing line generates massive costs. Our goal is to quickly locate the fault and restore the machine to full operating efficiency. Combining engineering knowledge with workshop facilities in Kojszówka allows us to easily handle both complex system diagnostics and major overhauls of main components.

Hydraulic Power Reconditioning for Powerscreen

An extensive power hydraulics system is responsible for dynamics, conveyor drives, deck unfolding, and crushing in Powerscreen equipment. WIBAKO features a dedicated section of mechanics focused exclusively on hydraulic systems. For years, we have been reconditioning piston pumps, track and belt drive hydraulic motors, and control valves from esteemed manufacturers used in Powerscreen machinery, such as Bosch Rexroth, Danfoss, Parker, and Eaton.

Safety Guarantee

Stationary Hydraulic Dynamometer

Reconditioned hydraulic pumps and motors are installed on our proprietary diagnostic test bench. We perform load simulations at maximum operating pressures to verify:

Pump flow and volumetric efficiency under load

Internal tightness of sections and relief valves

Parameter stability as oil temperature rises

This gives you peace of mind that the restored hydraulic part installed in your screen or crusher will handle the toughest tasks without risk of leaks or power drops.

When to React?

Symptoms of Hydraulic Failure in Powerscreen Machines

Ignoring warning signs coming from hydraulics can lead to pump seizure and contamination of the entire system with metal shavings. Contact us when you notice:

Conveyors or drum slowing down under load – the machine loses operational speed as the hydraulic oil heats up.

Loud, whistling sound at the main pump – a symptom of cavitation or physical wear of the race and pistons.

Lack of power in the crawler drive – difficulty moving the machine around the site or pulling to one side.

Rapid increase in oil temperature – system overheating causing a drastic drop in working fluid viscosity.

Metal shavings in return filters – a critical sign indicating the destruction of internal pump or motor components.

 

 

Over 30 Years of Experience

Combustion Engine Overhauls

Powerscreen crushers and screeners are driven by efficient diesel engines from brands like Caterpillar, Perkins, Deutz, Scania, and Cummins. Continuous operation under variable yet high load places heavy demands on crank-piston and injection systems.

At WIBAKO, we perform comprehensive rebuilding of power units. Our procedure includes:

Complete disassembly and cleaning of block and cylinder head

Precise micrometric measurements of crankshaft, sleeves, and pistons

Grinding and head reconditioning

Replacement of repair kits with OEM-quality components

Calibration and testing of fuel delivery system and timing mechanism

12-Month Warranty

Professional Engine Dynamometer

The culmination of every overhaul at WIBAKO is a multi-hour test on our stationary engine dynamometer. During testing, we record operating parameters in real time:

Actual power output and torque

Lubrication system pressure and cooling temperature

Exhaust smoke and temperature

Fuel consumption under extreme load

We provide a 12-month written warranty on engines reconditioned in this way, giving you complete peace of mind.

What Not to Ignore?

Troubling Engine Wear Symptoms in Screeners and Crushers

Starting difficulties – the engine struggles to start, especially at low temperatures or when fully warm.

Thick exhaust smoke – black (injector performance drop), blue (burning engine oil), or white (coolant in combustion chamber).

Uneven idling speed – surging, knocking, or troubling vibrations transmitted to the machine frame.

Leaks and blow-by from crankcase breather – excessive crankcase pressure indicating worn piston rings.

On-Site Repair at Construction Sites and Quarries

Powerscreen Mobile Service

We fully understand that transporting a multi-ton crusher or screener from a quarry or construction site to a stationary workshop generates huge costs and complex logistical challenges. For this reason, our mobile service travels directly to the machine's location across Poland. The technical vehicle fleet consists of fully equipped, self-sufficient repair units equipped with advanced hydraulic testers, portable flow meters, and dedicated diagnostic software. This allows our engineers to swiftly locate the source of failure in control systems, track drives, or power hydraulics without leaving the job site. Our mechanics have years of experience with recycling and extraction machinery specifics, allowing us to efficiently resolve complex faults in challenging field conditions and minimize unplanned downtime.

 

 

Components Available Off the Shelf

Comprehensive Spare Parts Warehouse

The speed and efficiency of any repair directly depend on immediate availability of the right components, which is why we eliminated long waiting times for distributor deliveries. We have a massive warehouse inventory and an integrated e-shop featuring over 30,000 products available in stock. In our permanent inventory, we hold parts for Powerscreen machines divided into three clear categories: brand-new items, tested used components from disassembly, and professionally reconditioned parts restored in our workshops. We offer complete hydraulic pumps and motors from Bosch Rexroth, Danfoss, or Parker, advanced control valves, engine parts for Caterpillar, Deutz, or Cummins, as well as undercarriage components, sensors, and filters. Thanks to precise OEM part matching and full integration of the e-shop with our service team, mechanics dispatched to a call take the necessary components straight from the warehouse, enabling immediate fault resolution on-site or same-day courier dispatch.

 

Do you service older Powerscreen Pegson crusher models?

Yes. Our experience covers both the latest Premiertrak and Trakpactor series machines, as well as classic units from the Pegson line.

Do you help with precise part selection?

Absolutely. If you don't have the part number, simply provide our advisor with the machine's serial number, equipment model, and the nameplate from the damaged component (e.g., a hydraulic pump or engine). Based on catalogs and our own database, our specialists will accurately select the right replacement or original part.

How long does delivery of an ordered part take?

Most orders are processed within 24–48 hours of payment receipt. Delivery time depends on the chosen carrier and the destination.
