[C320-list] Schaefer 2100 Furling System Stop Pin

[resloat]

Mike-On my Schaefer 2100 system on hull 894 (2002) the manual shows that the 
stop pin stops the foil from coming down and possibly touching the 
turnbuckle.  The clamp on the top of the torque tube keeps the foil in place 
and the stop pin is insurance that the foil does not go down if the clamp 
ever gets loose.  I would not let the foil rest on the turnbuckle and 
possible turning it when furling or unfurling the genoa.  Worst case is the 
turnbuckle could eventually come undone and the mast might come down.

When reassemblying after adjusting the turnbuckle, the manual says to raise 
the foil above the stop pin by wrapping a halyard around it to help do this, 
tighten the clamp on the foil and then screw in the pin stop until it is 
flush with the outside of the torque tube.  The pin does not screw into the 
foil.  The clamp keeps the foils in place.

I would raise the foil above the stop pin hole, tighten the foil with the 
torque tube clamp and then screw the stop pin in to the torque tube. 
Everything should be good.

Subject: [C320-list] Schaefer 2100 Furling System Stop Pin


Early this spring I disassembled the lower drum assembly on my Schaefer to 
due
some PM and check the bearings. I have never done this to this system and 
the
unit was laying on the ground and not under any load or stress, I have also 
had
no issues with Schaefer furler in the past. Following the manual, I
disassembled the lower unit without issue and I adjusted the Catalina
turnbuckle located inside. When I reassembled the lower unit the stop pin 
would
not thread all the way into the Torque tube. I could see that the stop pin 
was
hitting a foil assembly. No matter what I did I could not find the old hole 
in
the foil to accept the stop pin completely and I concluded that after 
adjusting
the turnbuckle the old hole had now shifted inside the torque tube and I 
would
need to drill a new one; which I did. After we launched, I notice that the
Schaefer furler now had a very noticeable bind in one spot while rotating.
Following some choice descriptive words, best not identified for this 
discussion
group, that I focused at myself, I concluded that I must have tighten the 
stop
pin to tight and it was binding against the forestay. I removed the stop pin
and hallelujah my Schaefer spins as it once did. Now after all this verbage 
you
have got to wonder what the hell is my question, which is: What does the 
stop
pin do ? According to the manual it keeps the foils from falling down the
touque tube and riding on the forestay turnbuckle. In my system the foils
already ride on the top of the turnbuckle and maybe this is what Catalina
intended since their turnbuckle have a neat cyclinder shape and therefore 
would
not bind like a foil could on a typical beveled-headed turnbuckle. Have I 
quess
right and feedback ?
