How much trouble is it to replace the rope assembly?
The machine was designed to make this job easy. You first open the hinged top cover, that gives you access to the rope assembly, then find the coloured joining disc, undo the four bolts, attach the new rope assembly to the old one, use that to pull the new assembly through, detach the old one and join up the ends of the new one after knocking the housing back down a little. It’s all done with minimum down time. Then you re-tension the new rope assembly.
