For tighten the wire use the nut on the wire on the quadrant. Tighten the wire terminals on the
quadrant till you can push the wire 1 -2 cm with 5kg pressure.
Grease in the quadrant wire tracks gives a good feel.
The chain should at all times be properly greased on the complete length of the chain. Dismount
the brake spinner and the wheel from the steerer shaft. Now unscrew 6pcs screws to dismount
the bulkhead steerer to get to the chain and the sprocket on the shaft.
Check that the sheaves are properly mounted and that the sheave wheel isn’t worn down or
loose in the sheave housing. Check that the wire isn’t fractured or worn down. The sheave and
the wire does not grease at any time.
Check the rudder stock for signs of electrolysis annually. This can be seen by circular corrosion
on the shaft.
Another point is the connection between the rudder shaft and quadrant. Check carefully that
there is no clearance between the parts. Check the vertical locking of the rudder annually.
The bottom bearing doesn’t need any maintenance except for a good hose down when the ship
is taken out of the water. The main reason for this hose down is to remove the salt water out of
the bearing housing so it can’t crystallize.
