Agricultural machinery mechatronics engineer Jonas Enneking from Damme in Lower Saxony and his colleague Leonard Meyer are facing a major operation: in Kirchlengern, a good 70 kilometers away, a tractor is waiting with two problems. It is leaking oil and the valve on the front power lift is defective. Equipped with a tire trolley, impact wrench and jack, the two get to work. The oil loss turns out to be a tricky case: in order to repair the leak and replace a defective O-ring, the rear wheel and wheel weight must first be dismantled - a lot of work for what should be a small repair. From one problem to the next: the valve for the front power lift is also defective. And in this case, too, thorough preparatory work is necessary, because before the old component can be replaced, all other hydraulic valves must be carefully unscrewed. __________________________________________________ Author: Johanna Langer (Video Arthouse) Editor: Thomas Kensy Funded with funds from nordmedia - Film- und Mediengesellschaft Niedersachsen/Bremen mbH. ___________________________________________________ Our guidelines for comments: https://www.ndr.de/service/technische...
