I own a 1997 Catalina 28 MkII tall rig. The topping lift is off its sheave (port side, aft) and jammed between it and the masthead box. This probably means a broken sheave; I intend to replace all four of them. Through binoculars, the forestay and aft stay appear to attached to the masthead box. In addition, I don't see any obvious way to pull the sheaves without taking the masthead box off.
Can the sheaves be replaced by climbing the mast and pulling them from the masthead box? Or, does the mast need to be brought down, the stays removed from the box, the box pulled and sheaves replaced?
Thank you,
SJ
