Hi, all I can say is DONT DO IT! Once you remove the coil section it will probably break, already you have broken the factory water tight seal and there are no internal spares available anyway! The handle is replaced as one complete unit, if you need more details I am an authorised Braun agent and can help you further. Give me a call on 01273 734424. Jason BRAUN SERVICE
