Wipe off any excess compound from around the drive shaft then refit to the mast.
Reassemble the drive assembly. When turned the spool should spin freely. If it does not,
remove the spool again and file the edges further. Repeat this until the spool spins freely.
In some instances it is possible for a wiring tube to rest against the drive shaft. This should
not cause a problem unless it is really forcing hard. In this instance the rivets holding the
tube above and below the shaft will need to be removed, reducing tension on the tube. If
possible re-rivet the tube over to one side. No damage will result if the wiring tube rubs
slightly on the shaft.
INSTALLATION INSTRUCTIONS - Fitting the boom and mandrel.
With the furling mandrel positioned inside the boom shell lift the boom into position on the
boat.
Attach the boom to the gooseneck using only the gooseneck vertical pin supplied.
To fit the vertical pin, align the gooseneck spacers and knuckle with the tangs on the mast.
Once fitted in position, fasten the pin in place with the washer and screw supplied.
Check to ensure that the vang and mainsheet tangs are tight in position, as they may have
become loose in transit.
Fit the mandrel to the drive shaft.
Slide the universal coupling onto the drive shaft (which will have to be cut to length) until
it touches the Inner Bearing. If when fitted the shaft protrudes through the back face of the
universal drive coupling, the shaft will need to be cut shorter by the length that it protrudes.
(See Diagram 8)
This is extremely important as the universal will jam in operation
and may cause considerable damage to the components or mast.
Diagram 8 shows
end of the shaft (tinted blue) flush with the inside of the universal boss.
The shaft must not extend past flush.
Using the correctly sized drill bit, drill the Universal drive pin hole.
The universal has a machined hole on one side, hidden by an O-ring.
Remove the O-ring and drive pin. Use a business card, or similar
thickness piece spacer between the universal face
and the inner bearing casting face to give a small
amount of clearance, otherwise the whole unit
may end up tight when the pin is installed. Through
one of these holes, drill into the drive shaft approx.
3/16”. Fit the Universal drive pin into the hole to
avoid any misalignment and rotate the mandrel
180 degrees. Drill into the drive shaft the same
depth on the other side.
