my sheave on my deck mounted cheek block fell apart today. when I went to order a new wheel, they told me I had to order a whole new block, so I ordered 2, but they couldn't tell me how to remove the old one!!?? They said a sealer was used, but i don't want to damage the deck in my usual attack method. This is on a catalina 22 thanks for your help jkleid@bestweb.net
