The upper block includes a frame, a plurality of sheaves, and a removable sheave pin that defines and axis of rotation for the sheaves and supports the sheaves within the frame. The pin removal assembly includes a sheave support mountable to the frame of the upper block and a pin support mountable to the frame of the upper block. The pin support is configured to support the sheave pin when the sheave pin is removed from the upper block.
