the cutting attachment hl for the stihl km 85r. the blades slide forward causing them to stop. the large cog wheel is losing contact with the drive pinion. do i need new bushings for the large cog wheel.

many thanks

i went to my local sthil dealer and told him what i thought i needed. when we looked up the spare parts diagram i saw right away what i was looking for. the spares are called needle bearings costing £3.71 each +VAT. the old ones had worn away completely and when i fitted the new ones the hedge trimmers are now working perfectly again.
