Recent project: Renk propulsion gearbox for cattle transporter


Cattle transporter was experiencing very severe oil leakage (in excess of 200 liter a day) with the propulsion gearbox and decided to open up the gearbox for inspection. Upon inspection, the owner diskovered that the one of the pinion gear has fractured and that the bull gear was also badly damaged with the wear baised to one side (suggesting that the bearing housing and/or bearing may be damaged). After some deliberation, the owner decided to rework the bearing housing and replace the complete gear internals (1 x bull gear and 2 x pinion gears).
