This video demonstrates the repair of a Bosch GBH2-24DRE rotary drill, which was damaged with a burnt-out armature and a field coil with darkened, burnt windings. The problem was that the armature could not be removed using the normal method. Therefore, a hole had to be drilled in the bearing housing at the rear of the armature to allow a small shaft to be hammered out. Once removed, it was inspected and found that the field coil was still functional without any internal short circuits or grounding. The damaged area on the coil guard, which had bulged, was trimmed, and two coats of varnish were applied before cleaning the gear assembly and applying new grease. After that, the drill was reassembled according to normal procedures and tested, and it was found to be functioning normally. Caution: Because the field coil showed signs of burnt winding coating and was not replaced, even though it is still usable, it will not be in perfect condition. Therefore, the machine should be allowed to rest periodically during use. Shouldn't be used hard for long periods of time without resting. This clip will demonstrate how to repair a Bosch gbh2-24dre rotary hammer which is damaged. The armature shot and the field coils are burnt out, but the problem is that the armature can't be taken out in a normal way. Therefore, a drill must be used to drill ball bearings at the end of the armature to be able to use a small shaft to hit out. Once removed, check that the field coil can still be operated with no short circuits inside the coil or ground. Therefore, the wound was wound around the coil card that swelled out. along with applying varnish 2 times before cleaning the gear set and applying new grease and then proceeded to assemble it according to the usual steps and try it out and found that it can be used normally in all respects. Caution, because the coil field has burnt traces of coil sealant and has not been replaced. Even if it works, it will be in perfect condition. Therefore, the device should be rested for some time during use. Should not work continuously for a long time without Rest.
