V8-250: Alternator Options

Post by classiclife » Fri Jan 11, 2019 3:09 pm

Hello,

With 90% of the work now completed on my Daimler, I took it for its recommission drive today and I'm pleased to say all is good. Thanks to those who have helped on my previous threads - plenty more of those to come !!

I did note however that the alternator a Lucas 11AC (ref: 54021122) is noisy and likely the original unit - without doubt bearing wear rumble and yet still charging okay at the moment.

Am now considering my options as to a replacement. Having spoken with decent auto electricians regarding this particular type alternator, their common warning note is the rarity of the rear bearing which if worn are like hens teeth to find and replace. In essence these units are becoming harder to source and overhaul.

That aside, I note SNG Barratt is selling an uprated unit (C25073) which is an identical swap for the current one in my Daimler - the upgrade provides an additional 10amps over the original 11AC.

SNG were unable to confirm if any additional fitment application was required.

As such, can I ask if anyone has purchased one of these units and if so, is it really a straight forward swap or is there some fettling / wiring amendments involved ??

DMG could not assist, which is a pity as I find them very on the ball and informed.

Failing the above, is there any other alternatives worth considering ?? I will not be asking extra demands on the alternator so not looking for a unit that matches the output of the National Grid !!

All advice welcome.

Thank you in advance.

The one I am considering for mine, when the time eventually comes (still i n the bodywork repair stage) is from Fosseway where I am looking at getting the uprated brakes and Starter motor from too.

If you car originally came with an alternator, then the SNG Barratt one, as referenced above, will fit.
For cars that originally came with a generator, it requires the correct bracket seat up to convert to alternator(unless one uses the 'Dynalite' which is same dimensions as the Lucas C40L.) the original daimler dynamo bracket is something of an afterthought and both poorly designed and constructed.. it is one of the most common parts attached to engine that often break..It can however be strenghthened and any experienced metal fabricator can figure out the weak spots and how to strengthen the bracket to help it hold up longer. .
The later cars with alternator had a vastly improved bracket that holds up far longer.

Thanks to you both, the SNG route appears the way forward and ticks the boxes.

Fosseway - I love their photos & products, but as for parting with money, there are other priorities !!

All the best.
