A H Spares Alternator Bracket

[RAC68]

Hi Dog,

I addressed the alternator installation issue a while back with a commonly available inexpensive Delco unit. Back then, I looked at the available brackets and felt they way too complex and expensive and decided to use my original generator mounting plate. This is the writeup I provided then to address the issue on my BJ8 phase 1and2:

Given the wide spacing of the two ears I should think it will accommodate most any alternator and you would simply need to use the correct size bushing(s) to get the pulley in alignment with that of the water pump and crank pulley. I have a similar appearing bracket I purchased years ago from some UK source that I have used in conjunction with a big Leece-Neville/Prestolite 70AH unit

Thanks Ray, great write-up. I ended up doing something similar with my Delco 10SI. My thanks to all who chimed in.

The forward 'ear' appears to be in the same place as that of the stock Healey mount.

I may try mounting the smaller mounting ear on my Denso inside the gap next to this forward ear.

I may switch to the Denso 50amp Toyota Forklift alternator and mill away part of the large mount as Dougie has done - IMO this is the cleanest non-Lucas setup.

Re the original brackets, does the one for the later (C42?) generator have a different spacing to the earlier type?

Steve--


If you have not yet purchased an alternator check out the Leece-Neville/Prestolite line. I don't have a model # for you but the 70 amp one I have has an externally mounted plug-in voltage regulator, making it extremely easy to fix what on most units must be done on a bench involving an R&R and teardown. I have had the alt on the car for perhaps 15 years/75 K miles and took it off for the first time last year for an inspection--though things were probably okay for another five years I recreationally changed the bearings and VR.

BTW, and not that it matters to most folks whose later Healeys use narrow belts, but my alternator came with a two-piece shiv that, merely with the addition of proper washers, can be shimmed to receive the wide fan belt that came on 4-cylinder cars.

Yes, Moss lists one for all the 6 cyl cars except BJ8 and another for BJ8.

Michael,
If no model #, how about a picture on your car, also showing the mounting bracket?

Hello All,
I wanted to post a few pictures of how I finally finished up the alternator mounting. Although the DW plate was really tempting, I opted for the original side plate and fabricated up a bracket system for the Delco SI10, based on a lot of good input from those who've been there before me. A steel rod was cut to run between the plate's "ears" and tapped to take a bolt on each end. Then a couple of brackets were fashioned to attach the upper boss on the alternator to the forward ear. Two short water pump brackets were cut to size and drilled for the adjustable arms, then I had to turn a couple of spacers out of aluminum stock to attach the brackets to the lower mount. So far, so good. (Knocking feverishly on wood here.)

Thanks to everyone for the input!

Here is a piece of round/hex stock tapped to 5/16UNF. No idea where this stock emanated from but works well to space the rear bracket of a Lucas set-up as you can hold the hex with a spanner while fitting the bolts.

If only it were plated or even painted!

Got my Toyota lift truck alternator fitted to the AH spares bracket. Since I don't have a milling machine I made a wooden jig and used a carbide-tipped router bit in my drill press to mill down the mounting ear width. Carbide-tipped wood bits work fine on aluminum.

Now hopefully it'll mount up with the Don Lenshow/Hendrix curved brackets. More to come.

That set up looks pretty clean Steve.

Finished installation:



Fan belt: 10mm (3/8") x 1145mm (45-1/8")



Connector to car wiring: green pigtail to 2x white - Ignition; red pigtail to yellow/green - Lamp; black - 'Sense' wire, attached to junction of heavy brown hot wires at disabled voltage regulator.

The Sense wire goes to a hot source as near the battery as possible. Following some online advice, I'd originally connected it to the Ignition wire. That resulted in the alternator outputting 16 volts. Connecting the Sense wire as above resulted in a more normal 14 volts.

Connector fits many different brands of alternator, widely available on eBay, Amazon, etc.
