Mizzen Roller Reefing

Derick Gates SM2K #400 Brava
 

Hi all,


I just have had the mizzen shaft become uncoupled from the roller reefing. The shaft can be pulled out about five inches, and then it will come no further.  How is this shaft normally attached to the gear box?  I see a hex headed bolt on the inside of the shaft.  I assume that this bolt attaches the 90 degree bevel gear to the shaft, but then what connects the shaft to the gear box?


Has anyone taken this all apart before?


I will post a picture of the situation.

Hi all,

I was able to disassemble the mizzen gearbox after removing the mizzen and the mizzen foil.  It appears that the shaft connecting the winch handle to the gearbox has frozen up in its housing.  The housing screws into the main gearbox assembly, allowing the bevel gear at the end of the shaft to mesh with a larger bevel gear in the main gear box.

Greasing the main gear box can be done by adding grease from the top, between the piece that holds the foil and the main gear box, and from the bottom through the two small drainage holes.  The winch handle shaft may require disassembly to properly grease it.  Thus far I have been unable to get it apart.  I think I have to loosen the hex bolt that is at the end of where the winch handle inserts.  

I have added two more photos in the album SM Mizzen Gearbox to show how the winch handle shaft screws into the main gearbox.
