Thanks to Keith and Mick for the excellent tips on how to do this project
. Your help reduced the stress factor for removing the rudder
in the water to replace the bushings.
Today, we got the rudder
out without too much trouble. I had difficulty removing the bolt that goes through the rudder post and holds the delrin retainer in place. The bolt was slightly bent and I had to hammer a drift pin to force the bolt out. I rigged a crane out of two by fours with a block above the rudder post to support the weight of the rudder (see pic). Unlike Mick, I didn't have two strong divers ready to man-handle the heavy rudder. Once the retainer was removed, the rudder was ready to drop. My bride tailed the line to the rudder post while I held the rudder under water. She lowered it gently until clear of the hull
and she just let it hang there. Next I attached another line to the rudder post routed thru a block mounted on my radar arch
. She switched the new line to a sheet winch
and cranked the rudder out of the water. I put our dinghy
under it and she lowered into the dink. From the dink we manhandled the rudder to the dock
. It was seriously heavy...I'm guessing 80lbs.
I also had trouble getting out the top rudder bushing. It was a tight fit and had lots of crud around it in the housing. I worked it back and forth and sprayed WD-40 into it to lubricate it. After about 2hrs of playing with it, it finally came out. The top bushing is in good shape so I suspect the lower bushing is the "guilty party" making the noise
. I gave a short try at removing the lower bushing in the water, but it felt tighter than the top one. I will need a full SCUBA
tank and a bar the same diameter as the inside of the bushing so I can stick it inside the bushing and work it back and forth. I'm anticipating a tough job on that one based on Keith's & Mick's experience on the lower bearing.
After I get the lower bushing out, I'll send them both out to a company to duplicate them (see earlier post for details). I'll do a follow-up when I get the new bushings back and installed.
Overall, I think this job is doable in the water and removing the rudder was the easiest part. If I was in the yard, I'd be digging holes to allow the rudder post to clear the bottom of the hull
. See pics below.
