>Hello Awsinger - I totally agree with Steve (K7LXC) regrarding the need to replace cables on a  crank-up tower. I have used the same cables on my US Tower TX-472 crank-up for well over ten years and they are in great shape because I lubricate them twice a year with Pre-Lube 6 Preservative Cable Lubricant (which you can buy from Steve). 
>You do need to grease the motor drive system periodically to keep smooth operation especially during tower raising and also don’t forget the thrust bearing at the top of the tower. You don’t need to replace the cables unless upon close inspection you see one or more of the problems as indicated in Steve’s email.
