Abstract
A sheave liner for an elevator system sheave that supports a hoist rope with an elevator car suspended therefrom is replaced without having to remove the hoist ropes and without having to hang the elevator car by means other than the hoist ropes. The existing liner is cut and removed while the elevator car is suspended from the hoist ropes resting on the sheave. The new liner is rotated into its position and two ends of the liner are joined by either a mechanical bond or by a room temperature adhesive bond.
