Best used as a replacement Sheave Set for Classic Wilderness Systems rudders outfitted with the WS 3-Screw Rudder Pin and Block. Made the same specifications as the 3-part original sheaves. This modern reproduction is made in two parts, one side has the cylindrical spacer tube built into it.

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 blade pivot bolt. Gently pry the old sheaves away from the blade and-or push out the cylindrical spacer tube.

There could be some remaining molded material in the middle, pinned to the sheaves, on the edge of the blade, as seen in the photo above. This is typically associated with black painted blades. You can chip off and discard it, or try to utilize it again. This does not serve any vital function. The middle molding is not necessary!

Some Wilderness Systems rudder blades are likely to have a tiny Roll Pin as seen in the photo below. This is typically associated with un-painted blades. You can drive this pin out or you can drill the sheaves for it. The roll pin is not at all necessary!

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 be 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.
