Sorry, I just came upon this thread. Good job. If the bolts will not break free, you can replace the entire lower collar. Rotate the levers up so you can release the cables
, then release the interior
cable lever arms with a slotted screwdriver, though you may need to remove the entire collar to do so. Again, it's all about persuasion and the power of aluminum
to stainless corrosion
. When you get the collar removed, with the two handles, you will see there's a slotted screw fixing them to the control handle shaft. It may take a bit of penetrating oil
and "persuasion". Remove the entire control shaft, grease it up well (and exercise it to make sure it's completely loose). I just did one of these last week on a Cape Dory
28 from 1989. At first I thought it was a cable problem that made shifting gears and throttle so difficult. It was merely corrosion
. So, grease everything! The four studs should break free, though you may have to talk to them and use some vise grips in the area where the collar lies, so you don't damage any needed threads. While it's out, consider replacing the compass
harness, and installing led lights
, if it has old incandescents.
P.S.: You can replace the plate with a piece of white StarBoard or acrylic
plastic. The compass
just screws into this plate.
