Geared Up (S01E03)

The Mega Mechanics kick things into overdrive as they tackle a huge gearbox change for a bucket wheel. However, a stubborn bolt and looming storms could leave the 23-tonne gearbox precariously hanging. Meanwhile, a strange liquid on a gearbox at a coal mine prompts the team to play detective. Additionally, the cranes are kept busy as they handle the enormous parts of an underground longwall support and a dam radial gate, working tirelessly to get the job done.
