How about an LG-1400R washing machine that constantly runs the band that goes from the engine to the base that turns the clothes. This piece has a funnel shape and just like the base has a clamping hole which was broken and lost. Logically I assumed that it was a kind of screw and process to replace it with a conventional screw with nut and washers. When the machine is tightened, it works normally, the problem is that after some uses it begins to loosen and the band comes out again. It does not matter when you tighten the screw s loosen again. Someone who tells me what part I got to solve my problem.

Hello, if you mean the screw that holds the drum pulley, you can add some washers, first you put a pressure one on the screw and then a flat one and tests. Regards
