I replaced the sheaves at the top of the mast and it turned out to be pretty straightforward. They are held in by pins secured by cotter pins. Note the order of things before disassembling. I brought a curved piece of metal to hook under the sheave to prevent it falling and help position it. Also it helps to be higher than a bosun's chair will get you - so your eyes are a foot or so above the mast instead of level with the top. I brought an old tubular nylon climbing ladder and draped it over the top evenly and stood in the rungs on either side like stirrups to get this extra height. You could make something similar of rope.
Mine had aged, worn and cracked to the point the jib halyard jammed. I replaced them with some nifty metal w/ball bearing ones from Catalina Direct.
