You can extend the smooth running life of your furler quite considerably by overhauling the ball bearings. Inside you will find 45 ball bearings – dig them out, don’t lose them (!), give them a clean and get some Harken silicon lube on them – and get the whole lot back together again….
The bearings can go a bit “lumpy” over time, says Alan… You can buy replacement bearing kits from the P&B chandlery. The bearings come in two types – ‘normal load’ and ‘high load’ …. An FF needs the “high load” type, so be sure you get the right one.
