I had a look at this job today as I want to replace the cush drive rubbers and followed the manual to remove ECU, battery and the various covers. Two of the alternator bolts were easy, sort of 11 o'clock and 3 o'clock viewed from the rear.

Now I think there is a third bolt but couldn't actually find it with the limited access.
So is there a third bolt and roughly where is it?

The manuals (Clymer and a BMW reprint) say the alternator leads are plugged into the back of the alternator, but mine seems to have stud connections at about 9 o'clock viewed from rear and really tricky to access next to the starter.

I was hoping not to have to remove the ABS2 unit, but it's hard to see that there is enough space to remove the alternator rearwards.

Any hints or suggestions?

Cheers,

Ray.

They're 120 degrees from each other. Make sure you use a sturdy tool as the threads on those bolts tend to be corroded.

It's not impossible but you are going to have a biatch of a time getting the alt out over the rear brake line that goes from the rear m.c. to the abs system.
It is a whole lot less knuckle busting to remove the brake line 1st. You can leave the battery tray in, but get the steel brake line out.
And yes that 3rd bolt is at about 7 o'clock.

Others may say otherwise but......

Scott,

Didn't you have a good combination of slip and stick stuff to help get the new monkey nuts in?

Well, what a pain that job was. Thanks to the advice, I disconnected the rear metal brake lines but it was still really awkward getting the alternator out.

The RTV and dab of moly for reassembly was a real winner through. Once I got the alternator back in position then a) the rubbers hadn't fallen out and b) I lined up the coupling and it went on second attempt.

Now have a nice quiet K back again. The death-rattle when cold starting has completely gone so well worth the effort....

Hi guys...

Re: ""The RTV and dab of moly for reassembly was a real winner through.""

Wasn't there a 'sticky' from Scott with pics on this Alternator job ?? Couldn't seem to find it by that name if there is..

Regards all..........// Ernie in NH

I think I may have posted about it but I can't find that I took any pictures of it.
I had taken out the alternater to replace the regulator/brushes assy.
