You definitely have the diamond board. The pendent attachment is rock solid 
 engineering and does not fail. The pin is a plastic called UHMWPE (Ultra 
High  Molecular Weight Polyethylene) and is readily available at any plastics 
 distributor. It is self lubricating and is a great bearing material. You 
will  experience minimal wear over many years of use. It is ten times 
stronger than  steel by weight. 
The torque specs for the cap bolts are: snug it up and compress the gasket  
somewhat. If you find yourself breaking any bolts while doing this, you are 
 using to much pressure. I find several electric screwdrivers to come in 
handy.  If you have a ten year old with small hands, this would be a good time 
to  introduce them to the joys of sailing.

Hi  gang,
We're having a little bit of nice 60 degree weather here in Tennessee  in 
the middle of February so I celebrated by pulling the centerboard from  
Harmony.  I've got some questions and am hoping you can provide  answers.
Does anyone know if there is a torque spec for the 50+ bolts that  hold 
the cap on the centerboard well?  Some of the bolts on Harmony  were not 
very tight, some were kinda tight, and some were fairly  snug.
There was no hose in the slots on either side of the board.  I  guess 
that's why the board rattled so much even when it was up.
Take a  look at the pictures.  Can anyone tell me if the centerboard is 
the  diamond board or the older standard board?
One picture shows the  centerboard pin.  It looks to me like it is solid 
fiberglass.  ??  Does this make sense?  Seems like I ought to replace 
this  with a stainless pin with plastic bushings.
One picture shows the  connection of the centerboard pendant to the 
board.  Not sure whether  I like it or not.  Anybody have any opinions 
about its  reliability?
Thanks,
Joe
