Braun 3000s electric shaver: Quality of the shave had been deteriorating over the last few weeks and when I looked at the drive components the pegs that engage with the cutter heads had worn almost away.
This is a set of components called "Oscillating bridges" These are readily available as a spare (Part #67030836) bought from Amazon market place, Sussex Spares for £9.99 delivered.
To replace the whole set remove the plastic drive components, they just pull off, note which side the dual piece is. With a suitable torx driver/bit undo the two screws and prise off the plastic cover and then the seal cover.
Slide off the rest of the cover to expose the motor drive components.
On the non-button side of the body slide up the cover and take it off.
Underneath is a rubber seal that the prong on the white plastic drives from the motor fits into. Remove the old ones and fit the new with a small blob of graphited grease on the motor's eccentric and ensure the peg fits in the seal.
Reassembly is the reverse of disassembly. When putting in the self tap screws rotate them anticlockwise until they "click" down and then clockwise as nornal until tight. This ensures that the screw is properly engaged with the thread. Refit the rest of the components making sure they click down properly. The single lower element has to be the right way round to mate with the plastic round the drive pin
Shave is now back to full standard.
