Line up sheave with
center of spool
A drill press is preferred when drilling the shaft, but, if drilling through the shaft with a hand
drill, make sure to drill at the proper angle so as to pass through the center of the shaft. Use
a metal cutting compound to avoid work hardening the drive shaft. You may find it easier to
pass through the shaft with a smaller drill first. If drilling through the shaft with a drill press,
remove the shaft once center drilled. When reset up actually ream the hole with the drill
until the pin is a tap in fit. It must not be a drive fit. Debur the edges of the hole then refit
the spool to the mast.
Align the drive pin holes and fit the drive pin. Use a grease or similar when fitting the drive
pin so as it assist with future removal. Fit the leather cover and O-ring over the inner
bearing casting flange. Slide the universal onto the drive shaft. Roll the O-ring into the
groove, retaining the drive pin and pull the leather cover over the universal coupling.
DECK LAYOUT
Consider the layout for leading the halyard and furling line aft. If the existing vang and
topping lift lines terminate at the mast, it would be desirable for these to lead aft also.
The following diagrams offer suggestions which have worked well on previous installations.
