The 'E' Type Forum

Dear Forum colleagues,

next job on my list to get the E running again is the refurbishment of my Butec alternator.
I have started disassembly to change the bearings which have really reached end of their life.

Now I'm wondering if the unsoldering of the outer slip rings is really a DIY job?
I'm afraid that if I damage something the alternator might be ruined.
I have refurbished several Bosch and Delco alternators but there I never had to remove the slip rings.

What is your experience?
Did you do it by yourself or did you rely on a professional workshop.

Thank you for advice

Sven

So today I got my 12t workshop press and have pressed out the rotor.

No I have to remove the rear bearing and the slip rings.
Did no one do this before and can give me a hint if it is a straightforward job?

Thank you for advice
Sven

Hello Sven,
I've done this many times and it can be either straightforward of not. The un-soldering from the outer end is not much of an issue; the inner end is a little bit more difficult. Care needs to be taken with the end of the wire that is soldered to the inner end of the Slip Ring not to stress it. Only a very short length protrudes form the insulating resin and you can't afford to lose any of it.

The fiber washer nearly always gets destroyed in the process, so you will probably have to make a replacement.

Regards,

Bill

Hello Bill,

thank you for your feedback.
I'll try it.
I love to do all the necessary repairs by myself, this is my main hobby.

best regards

Sven
