Reparación de rotomartillo percutor Bosch que no gira ni percute pero el motor si funciona

In this workshop video, I'll show you how to diagnose and repair a Bosch rotary hammer drill that has stopped working: it no longer drills, hammers, or rotates like a drill. These types of failures are common in heavy-duty power tools, and users often think they're beyond repair. However, with a proper diagnosis and the replacement of key parts, it's possible to restore its useful life and avoid spending money on a new tool. 🔧 What will you learn in this tutorial? How to identify the most common failures in a Bosch rotary hammer drill. Checking brushes, springs, and armature to prevent damage during disassembly. Diagnosing the internal mechanism: piston, connecting rod, and gears. Detecting and replacing worn gears. Cleaning metal shavings that can jam the armature. Applying fresh grease to protect gears and bearings. Correctly assembling the piston, key, and function selector. Final percussion and rotation test to confirm the repair. 💡 Step-by-step explanation: First, the rotary hammer was connected to verify that it was not functioning. Upon disassembly, the brushes and armature were inspected, taking care not to damage them during disassembly. During the inspection, it was discovered that the main gear was worn, preventing the piston and connecting rod from transmitting the percussion and rotation motion. An identical new gear was obtained, as the previous one had lost several teeth due to excessive use and improper force application. Before installing the part, the inside of the mechanism was carefully cleaned to remove any metal fragments that could jam the armature. New grease was then applied to ensure smooth operation and extend the lifespan of the components. Reassembly included installing the piston, spring, and key, correctly aligning the parts so they meshed smoothly. Finally, the brushes were reinstalled and the rotary hammer body was reassembled, taking care that the wires weren't crushed. In the final test, the rotary hammer worked correctly again: in the hammering position, it struck and rotated, and in the drilling position, it rotated normally. 🌍 Why is this tutorial important? Rotary hammers are indispensable tools in construction, workshops, and DIY projects. Knowing how to repair them not only saves money but also promotes a do-it-yourself (DIY) culture and preventative maintenance.
