Hydraulic Repairs

Dismantle & Assessment

•    On arrival all components are documented, cleaned and completely dismantled
•    All wearing parts are precisely measured and the result recorded
•    Hydraulic components that have excessive or unusual wear are subject to further review
•    The results of the inspection procedures are then used to develop an effective scope of work

Quoting & Procurement

•    Internally developed, Quality Assured disassembly and inspection sheets are utilised to provide efficient and accurate information transfer between the technical and administrative staff
•    An extensive inventory is maintained, ensuring fast turnaround and reducing reliance on secondary suppliers
•    HYCON has access to genuine parts for the world’s leading brands through a diverse international supply chain

Grinding

•    All surface grinding is completed in-house to maintain quality standards
•    A larger diameter wheel is used to ensure superior finish
•    This grinder is supported by a large range of jigs and fixtures to facilitate rapid turnaround

•    Both flat and spherical components are catered for
•    Optical flats, in conjunction with monochromatic light, are used to check flatness lapping
•    All lapped components are ultrasonically cleaned to remove any residue

Assembly

•    All components are reassembled by skilled technicians with years of experience using Quality Assured processes
•    All critical dimensions are counter checked, with measuring equipment that is calibrated monthly
•    All critical specifications, assembly dimensions and tensioning requirements are recorded for quality assurance and future reference
•    Overhead cranes with creep mode hoists enable the precision assembly of large and heavy components

Testing

•    All hydraulic components are subject to an exhaustive and authentic function test using a facility unrivalled in Australia
•    Four test stands are available (110,250,300 and 1000 kW), and these can be run simultaneously
•    The largest pumps can be tested at full displacement and design pressures, at the correct speeds
•    All tests are logged and analysed using Hydrotechnik 5070, 8050MC hardware and software with VSE flowmeters
•    Special care is taken to protect components when testing, oil flow is full flow filtered to 10 micron and off line filtered to 3 micron

Sealing & Packing

•    Ports on repaired components are sealed with steel blanks at the completion of testing, preventing ingress of contaminants and loss of oil during transportation and storage
•    Unpainted machine faces are coated to prevent corrosion
• All components can be packaged and transported per customer requirements. Hycon can offer the following Options:
          - Metal Transport Box
          - Wooden Crates
