Our inspections can include:

  • Visual Inspection

    If the gearbox requires dismantling due to opera-tional damage, the entire gearbox will be thorough-ly visually inspected and a NDT study carried out on the gears.

  • Videoscope Inspections

    To prevent dismantling of the gearbox, we can per-form an inspection by videoscope. To inspect rolling element bearings and gears, we use the latest vid-eoscopes from General Electric. These videoscopes allow us to identify problems, often impossible to see with the naked eye.

  • Contact Pattern Checking

    Before dismantling the gearbox we check all the contact patterns.

  • Check Dimensions and Tolerances

    During strip down of the gearbox or major overhaul, all rotating part dimensions are checked against the latest OEM acceptance and applicable engineering criteria.

  • Alignment Checking

    Second to rotor unbalance, misalignment is a frequently encountered problem. HKJ Group is able to handle both hot and cold alignment projects on a range of machinery including reciprocating com-pressors in addition to rotating machinery.

  • On-site Troubleshooting

    Our knowledge, experience and equipment allows us to identify potential machinery malfunctions, such as rolling element bearing defects, gear relat-ed problems, rubs, resonances, etc. Significant and valuable time can therefore be saved to resolve the problem.
