Look at this link for more information in installing the furling line. His furling line runs on port side, mine runs on starboard side so rotation of drum is opposite. I have Harken Furler circa 1984. I removed the old line (3/16") and replaced it with new line (3/16") several feet LONGER than original to play it safe. Note: I removed the head sail from the system before replacing the line. My boat is a 25' Mirage and the jib is less of a monster to handle. The furling drum has a hole in the side of the drum which I passed the end of the furling line thru and tied a overhand knot in the end. The old line did not have a knot :) instead the line was turned over itself and STAPLED. There is not much clearance between the drum and the furler body for too large of a knot. In the linked video, the author recommends 30 revolutions of the drum to preload the furler. I didn't count mine because I used the same length of new furler line as the old. Once I had the drum loaded, I went ahead and reinstalled the jib and checked to make sure all was well and it was. kzfaq.info/get/bejne/hMmRorBqqrLLp4k.html
