Very new kid on the block(but with grey hair) and first time entrant to this august body of knowledge!
Purchased twelve months ago new Stihl KM 90R combi head along with whipper and blower. Within the shafts are white plastic sleeves/ferrels that appear to act as guides but also retainers of the drive shaft.Although the black plastic "boots" are replaced after use(to keep dirt out) I have gone through a number of the sleeves. I have also tried some lubrication but to no avail. One, has anyone experienced same and two,has anyone a remedy?
With thanks in anticipation
