Comprehensive On-site Inspection and Refurbishment of Kühnle, Kopp & Kausch Turbo Gearbox

Expert diagnostic assessment and precision refurbishment of an 850 kW power generation gearbox, focused on component lifecycle extension and lubrication system optimization to ensure grid stability.

We executed a meticulous on-site inspection and technical overhaul of a Kühnle, Kopp & Kausch AFA4 G5A gearbox, a high-speed parallel shaft unit operating within the power generation sector in Hungary. With a rated power of 850 kW and an input speed of 1,620 rpm, this gearbox is a critical link in the energy production chain, requiring absolute mechanical reliability.

Our engineering team conducted a forensic measurement of all rotating components and bearings to evaluate wear patterns and tolerances. Following this detailed assessment, our specialists determined that the primary rotating elements remained within operational specifications and could be professionally cleaned and reused, optimizing the client's maintenance costs. However, to ensure future reliability, the bearings underwent a full refurbishment. Simultaneously, we performed a thorough repair and cleaning of the gearbox housing and a complete decontamination of the lubrication system. This holistic approach ensures that the unit operates with peak thermal efficiency and minimal friction, safeguarding the plant against unscheduled downtime.
