Herald Alternator Update, Good old eBay! (originally published in 2009)

I had been keeping an eye out for the correct alternator bracket for the Herald as I wasn’t happy with the bodged up dynamo bracket.

A Dolomite 1500 was being broken for spares and I managed to buy the alternator mounting and adjusting brackets.

These as expected fitted well, and the belt adjusted correctly.

The belt pulley run also looks straight and the original belt can still be used,

Right, on we go!!

Now have the bolts, spacer and washers and have managed to (bodge) fit the alternator into place.

Not the most asthetic piece of engineering I’m afraid, however the Spitfire alternator brackets or quite hard to source and as a result quite expensive!

Everything is nice and tight and the belt run is pretty straight

Could probably do with a slightly longer belt I think, had a look in Halford’s today and the only ones available were either the same length or the 1500mm (a bit too long). I’ll go with the original for the time being.

I now need to fashion a little piece of aluminum or steel into an extension for the fan belt adjusting bracket, and then I will then complete the wiring.

Watch this space!!

So it begins, out with the old and in with the new(er)

Started with removing the dynamo (strangely enough:-))

Please note that the dynamo may foul the distributor.

Got around this by loosening it off and turning it away from the dynamo.

Be sure to mark the position of the dynamo before loosening so as not too put the timing too far out.

I put a small felt tip pen mark on an HT lead to line up with the LT lead of the distributor.

The dynamo was then removed.

Tried a few test fits of the altenator with the various parts of the existing dynamo bracket.

It would appear the best way to do this is to remove all the existing bolts etc (including the large one in the alternator and dynamo picture above) and replace them with two different size bolts and a large amount of washers to ensure all the pulleys line up.

The Herald fan belt will also now be too short, I’ll pick up an new one when I get the bolts.
