Best used as a replacement Sheave Set for Classic Wilderness Systems rudders outfitted with the WS 3-Screw Rudder Pin and Block.
You can see an example of the rudder assembly in the photo to the right. Bear in mind that many classic Wilderness Systems rudders did not have the logo printed on them and many of the blades were not painted at all.
This is a two part sheave set. The maximum diameter is 2 inches. The original sheave set was in 3 pieces (2 discs and one cylinder, aka spacer tube). This set is made with the spacer built in. The set fits into a 1/2 inch diameter pivot hole at the top of the blade. The spacer will accommodate a pivot bolt that is 1/4 inch in diameter.
Other parts might be needed for your restoration such as; about 20 feet of Rudder Rope (leave old rope in place as example until you ready to re-string it), and a Rudder Rope Tension Line Kit.
Instructions are NOT included. Please Take Note! First, memorize your rudder rope path (take photos as needed) and the orientation of the blade (front and back). Remove the pivot bolt with two wrenches. Gently pry the sheaves away from the blade and-or push out the center of the sheave on one side to remove the cylindrical spacer tube. The old sheaves will fall away (there could be some remaining material, possibly pinned to the sheaves, on the edge of the blade, chip off, discard or ignore. It does not serve any vital function). Press the two parts of the new sheave set together onto the large hole in the blade (there is no right or left). Re-string the rudder rope as it was before. There will a rope on top of one sheave and the other rope will be under the other sheave. The ropes change position (over and under) when the rudder is up or down.
