Lotus Elan and Lotus Elan Plus 2 Forums

Hi Bob. Not sure this adds anything to the previous advice. I had a few made up some years ago
and may still have one or two available. If your in UK, could possibly drop one in the mail to you
for a small fee + postage. (Well, smaller than SMS are charging....) You will need longer bolts thru the timing case at the 3-Bolt positions that its fitted to.
Weather it fits a LHD car, I can't confirm.

This one fitted to my Sprint.

Yes Roger, I could not see why it shouldnt be used with dynamo, I just assumed I was missing something!

Rose joint adjuster rods are readily available, see eBay. Although they make adjustment easy they do little else as far as support goes as they are effectively a radius rod. When using one, virtually all of the rigidity is supplied by the lower pivot point. Looks to be using a small Denso here and going by the one I have, use a single lower mount, Although it's quite beefy it's only about 1" wide. Make sure the bolt is good and tight after you have adjusted the belt as this will doing most of the support work. Dynamo owners will know how easy the mounting holes in the end plates go oval with time if the pivot bolts aren't kept tight. Unfortunately, they are often hard to get at when you have to use 2 spanners and can suffer from "good enough" when tightening.
The mount with the buffer reminds me of a conversion to a Volvo B18 engine in a car I bought that used a large Lucas alternator. The initial service included a new belt. Found that the adjuster arm was just jammed against the block and it just dropped out. It worked OK but I changed back to a dynamo.

Make sure the lower front mounting bolt securing the alternator or dynamo is properly tightened too. If it isn't a greater portion of the belt force will be transferred to the upper bolt and hence through the adjusting strap to the front cover. On Escorts the Ford factory bracket for alternator mounting was a very substantial affair with three point mounting to the block. Same bracket was used for LTC and standard crossflows. Never had problems with things breaking with that arrangement. I believe the same bracket can be used on RHD Elans but not LHD ones.

This one ?

That's the one.

@Phil: Thank you for the wonderful drawing! Sorry I did not see it before. It has been a very busy week!

@Gerard: I'll send you a message re parts and to help on your window guide (je t'enverrai un petit mot avec mon num?ro de t?l?phone)?

@everyone else: thanks for this very useful set of posts.
