The KZ100 Furler was used from 2010 to 2015 and was an excellent piece of equipment – when it worked.
However, salt water could cause the bearings to corrode which meant it wouldn’t turn easily.
KZ offered a solution (at the time) to replace the bearings with Ceramic ball bearings which resolve the corrosion issue. Or you can grease the bearings on a regular basis.
You may be able to send the furler back to the factory in NZ to get this done (for a price) but it may be easier to either DIY or get a local rigger to do it for you.
To disassemble the unit you need to access the thrust bearing.
The thrust bearing is located on the spindle, which is the central shaft of the furler. This can be accessed by removing the top fork nut and also the bottom end fittings off your furler.
Once the spindle is removed there will be 2 support bearings, one under the top fork and one in the bottom of the furler hub, these are press fit into place. They may need a bearing puller or small pin punch to lever out. If you wish to just re grease while the bearings are in place, use a small pick to remove the plastic ring covering the bearing, fill the bearing with grease and then push the plastic ring back into place. Depending on the age and size of your furler the disassembly steps may vary.
Ceramic bearings are available online in Australia here
