LHD Alternator Bracket

PostPost by: terryp » Tue Feb 07, 2012 3:16 pm

Hello
Has anyone a "proper" one of these that they can take a photo of for me so I know what to search for

Thanks
Terry
PS I have a 18ACR Lucas Alternator

Terry, do you mean the mount on the block or the slotted adjustment piece that pivots on a front cover bolt?
I have an alternator but not the Lucas

The one on the engine block. I beleive it lifts the alternator slightly compared to the RHD bracket (I had one of these on my old +2)

Thanks

That's for a RHD car. I have been talking to Sean at Spyder and we don't think it will fit.
I think it needs to be the same sort of thing with the mounting higher

Thanks

Thats the one. Could you measure center to center how much higher the alternator holes are from the holes in the block.
Also how far out from the block are the alternator holes.

Thanks

With the alternator in place you can't really see from above, you may be able see from below but I can only work on the car outdoors and it's snowing.

If it's the one (A050E0554) used on the +2 Fed cars, I have one on the bench and can get your measurements this morning.

Looks to be 0.575" or between 9/16" & 37/64". That comes in at very close to 14.5mm, although I don't know why it would be metric. :twisted:

Stay warm you guys!

Those brackets were fitted to both LHD and RHD late plus 2's with alternators - I have always thought they were identical in mounting height - but if they have different part numbers then I must have been wrong :cry: or maybe some other difference for the different part numbers. its strange to make 2 versions when the LHD version would suit both LHD and RHD cars :o

I would love to see the differences in dimensions - I have a RHD one and will measure it up

Just as a side note these are especially valuable for a high reving race twin cams if you use an alternator as they dont break with all the engine vibration you get above 8000 rpm around the front of the engine. I am just replacing the alternator top adjusting arm today on the elan as they fatigue and fail after about 2 years of racing. I am on version 5 now and each one has been stronger than the last - maybe this one will not fail.

Not easy to find them and a good candidate for someone to CNC machine a batch for sale in both LHD and RHD versions maybe

The one that came with my Plus 2 now resides on my Elan and an new one for the plus 2 plus a spare would be nice

cheers
Rohan
