Alternator Bracket Arrangement

PostPost by: 111Robin » Tue Feb 01, 2022 8:23 pm

Can someone please post a photo showing how the alternator strap and bracket should be fitted, plus 2 if it is different. I get how the forked slotted bracket fits (item 20) but the additional plate with three holes (item 21) is confusing me. How is this arranged on the engine ?.

Hi, Item 21 is fitted to the rear of the timing chest, attached by the through bolts. See pictures I posted here :- viewtopic.php?t=16002&p=80454 .
Cheers, Brian.

Ok, so the bolt that passes through the forked end also passes through the centre hole of item 21 ?. Difficult to make it out on the photos.

That's correct.I believe the idea of the plate is to brace the lug on the covers to stop it breaking off.
Pictures not easy to take when installed in the car!

Thanks Brian, this plate was missing when I removed the alternator hence the confusion. I think I understand the arrangement now.

Note in the photo above the arm itself is not the Lotus original which was straight and not curved and of much lighter construction but did mount in a similar way to the triangular bracket on the 3 front cover bolt holes
