Stus-List Re: C 37 Rudder post assembly

[Bill Coleman via CnC-List]

For crying out loud, Richard, You've got to take some calipers to the boat
and measure the od of the threads, and take a rule and measure the threads
per inch, and the number per millimeter - C had both metric and inch on
these boats. Failing that, take some pictures and  take the nut to a
machine shop. Did you get the picture I sent you of the top of my rudder?
Most bearing nuts will be in millimeters, as this
https://www.skf.com/group/products/rolling-bearings/accessories/lock-nuts/integral-locking
and the one shown here is not beefy enough for what you need.
Too bad I didn't keep my buddy's bent C Rudder.

Stus-List Re: C 37 Rudder post assembly

[Matthew Wolford via CnC-List]

Richard:

 

When you spoke with Rob, did you ask if he knows the diameter/thread size of 
the top of the rudder post for that boat?  He used to have a lot of specs on 
boats (including build files, which are no longer available).

 

In any event, from prior e-mail it sounded like some of the threads in the 
collar you have are not stripped.  Given that you’re on the hard, I suggest 
blocking the rudder in place (wood blocks and a scissor jack works well for 
this) and taking the collar to a machine shop as many have advised.  The shop 
will be able to quickly determine the size/thread.   Bill guessed 1 5/8" 13 
TPI, but taking the collar with you is best.  If you’re interested in ordering 
from McMaster-Carr instead of having one fabricated and do not wish to ask a 
machine shop for sizing, see if there is an industrial fastener supply (like 
Fastenal) anywhere nearby.  They sell big nuts/bolts and should be able to tell 
you the size.  I would also inspect the top of the internal bushing housing 
where the quadrant likely hit to ensure no damage was done.

 

Relatively easy fix, but some monkeying around.  Good luck!

 

Matt

To follow Up; I called Rob at South Shore; he was very patient and listened to 
my tale of woe; he said that there was no "off the shelf" part for this collar 
and that my best bet would be to have a local machine shop fabricate one; I

Hi all; I am in need the collective wisdom of the group for a rudder issue; my 
boat (1985 C 37 CB) has been sitting on a trailer since early September for 
repairs to the hull, not rudder related; sometime in the past week the rudder 
has dropped a full two plus inches and no one knows how this happened; the hull 
 has been painted and the painters said they moved the rudder by moving the 
steering wheel and had no issues;  does anyone have any ideas or suggests about 
what could have occurred? and more importantly, what needs to be done to make 
the rudder usable? 

  

  

We were hoping to relaunch in the next week or so...I'll be happy to provide 
more information if anyone has questions...Thanks!

I suggest starting there.  If Rob doesn’t have one, he may be able to suggest 
an alternate source.

Hi all; Bill is the winner for long distance diagnosing...; there is  a chrome 
"collar" or "nut' which is threaded and the the top of the rudder post which is 
also threaded; the collar is tightened down over the rudder post and sits on a 
delrin "washer" which is about 1/8 inch thick. There are two set screws in the 
collar to keep it tight n the rudder post.  The rudder pivots on this assembly 
when steering the boat.  

 

In my case, these set screws apparently loosened up to allow the collar to 
loosen which caused play in the rudder post. The result was to strip the 
threads on the collar allowing the rudder to drop.  The fix is to get a new 
collar, which I hope someone here can help my in identifying; there are no 
markings or part numbers on the collar. Of course, I have lots of photos.

 

For a quick fix, we were able to invert the collar and use the remaining 
threads ( about 1/2" to 5/8") to hold the rudder in place. I am confident that 
this will work until I can identify and order the new collar.

 

So it seems I have been lucky and my situation fits under Mike Hoyt's "good 
case" scenario rather than the whole assembly failing, which is the "bad case" 
scenario.   I feel a lot better than I did 24 hours ago, but will report back 
on progress.  I would have thought the C used the same assembly for all of 
the rudders regardless of the model of the boat, but maybe not...;

 

If anyone ha any experience or suggestions in locating the "collar, please send 
them on...Thank you to everyone!

I thought there was a nut on the top of the post. If so, it may have come off 
and it slipped down till the quadrant hit the hull. Obviously you are going to 
have to go down an look, and all things shall be revealed unto you
