I have a 13 torque 301 with cables on this slide. It moves the couch. It just stopped working all of a sudden. Im asssuming there is a shaft that broke cause the motor turns the gearbox? They look like they are seperated. I see the motor spinning when i press the switch to put the slide out. Its just not going anywhere. I know the chain has some slack too. Ill adjust that. But, what would i need to order? Im pretty good mechanically. By the way, Im not a heavy guy. Can you lie on top of the slide, or is this a no no . Its inside and not in the out position. Thats where its stuck right now. Thanks
