fix alternator misalignment

[deQuincey]

a new alternator from bmw gaved me the problem of a very accussed misalignment of the two front belts (alternator & steering drive)

the cause was due to the silent blocks present in the new alternator, so i fabricated a new aluminium block to substitute the rubber silentblocks, also upgraded the central screw from 8mm to 10mm (M10)

compare standard available silentblocks (left) with aluminium block (right)

Nicely done. How did you fabricate the aluminum bushing?

i only design the alu bushing by myself,
then i order it to a local workshop
regards

please help, comments !

any comment on the increase of stifness that the aluminium bushing will imply (compared to that one of the rubber silentblocks) ?

any increase of wear of pulleys, alternator elements,... expected ?

i will appreciate the comments

I've had a solid mount alternator on my daily driver Bav for a couple of years and I haven't noticed any wear or unusual treatment of the system.
