The operator looks similar to our 39-187. Please compare the dimensions and let us know if anything differs. I'm afraid I don't know what you mean by the screw jumping out. If the operator is worn down, that's what you will need to replace. If it's an issue with the track beneath the operator's arm coming apart, you need a new hinge set. See if the 36-004-10 matches up. |
