Another plug in alternator upgrade

I decided to bump up the juice a bit with this bad boy:

eBay 95 AMP Triumph New Alternator

Hmm, "high quailty" ... does that mean you are likely to draw away in disgust? Or are they just giving you the bird?
:devilgrin:
 
Time for air conditioning now, Paul. Keep that baby cool with the hard top.
 
Paul, I thought those Lucas certificates and pictures looked familiar in the eBay description, then I realized this is the same place that rebuilt my TR6 starter and generator.....

3 years on, both still work fine, although they haven't gotten much of a work-out lately. I remember telling them then to advertise here on BCF.
 
Paul with out going to the garage and looking at mine I'm thinking the pulley looks to be a bit small. Or is that how they get some of that extra juice?
 
No, the pulley is smaller from what I was told by Greg on another forum. He has one and loves it. He simply bought a Mr. Gasket pulley, which happens to be chrome and probably what I will do.

As far as the A/C goes, that's one project that I can safely say I will not be doing. I love the top down too much and I only want the hardtop so I can drive it when it's colder, but not snowing.

And with the new seats, I'm really looking forward to summer.
 
I used the delco conversion on both my triumphs. My brother had one of the bosch alternators in his mgb and it only lasted about a year. bearing went bad.
 
Roman,

That is a very nice setup. I never saw that until today. Good price too!

I think that I will run this new one and keep my 55amp unit for a spare.
 
the 55w upgrade in mine seems to work fine,why the drastic upgrade Paul?

not like yur pushing a 1600w stereo'
 
Bill,

I did install seat heaters for the backs and cushions when I had the seats reupholstered. Just another "I can't seem to leave it alone project" for me.
 
OK, time for a pictorial update. I received the alternator today, via priority mail from California. Not too bad as far as I'm concerned. An eBay vendor that ships on time as promised is OK by me.

Anyhow, I pulled my old stock alternator off the shelf and took some pulley measurements to check things out. You will see the results below. And yes, you do need a new one, but only for the width. When you see the actual measurement at the bottom of the groove, the difference is negligible.

Front view and the stock pulley looks really big, doesn't it?

And the rear view.

And a side view. All looks good so far.

Close up of the back. I like the retainer clip to hold the connector in place.

95amp003.jpg


And the stock unit, so you can see the harness will plug right in.

95amp004.jpg


This is a good idea.

95amp005.jpg


Measurement time. Old pulley, bottom of groove or ID is 1.516"

95amp006.jpg


New pulley is 1.654" at the bottom of the ID.

95amp008.jpg


New pulley OD is 2.446".

95amp009.jpg


Old pulley OD is 2.879".

95amp010.jpg


Bad pic by me here. This is .380" at the top of the groove width.

95amp011.jpg
 
And the last one that wouldn't fit above.

And as you can see. this is .502" at the top or 1/2" versus 3/8".

95amp012.jpg


Now I need to check the belt width and how it fits in the groove, but that's for tomorrow. I do have the new Mr. Gasket 6808 pulley coming in UPS tomorrow.
 
Another pictorial update. Thanks to Greg's advice, the Mr. Gasket 6808 pulley arrived yesterday and it looks good. Nice chrome finish and it is wider and bigger in diameter. This will allow the use of a wider belt than the pulley that came on it. Perhaps if anyone orders one of these in the future, they can request the wider and bigger pulley.

95amp014.jpg


This is what comes in the kit from Mr. G.

95amp015.jpg


This shows the width difference.

95amp017.jpg


Here you can see the width and diameter difference.

95amp018.jpg


Almost the same size, so as Greg said, no belt concerns.

95amp019.jpg
 
Paul, I think the pulley goes t'other way around with bumped out part under your thumb fit in the recessed fan. Otherwise, it looks like there wouldn't be enough threads to get the nut on.
 
Peter, you are correct. You can see the indentation side of the pulley to be replaced on the new alternator in the first shot. That was just for illustration of the diameter on the old pulley.

I have some pictures of it all together, but I'm putting a couple of coats of clear on it now to protect the finish before I install it tomorrow.
 
A couple of coats of engine clear after the fan installation and we're almost ready to be mounted. After this dries really well for another day or so.

Peter, you will see that it is mounted correctly, which is the only way possible.

Time to install my new polished SS alternator bracket. I almost forgot I had this guy sitting on my bench.

95amp026.jpg


That is an 8mmX25 Metric bolt in there. I thought it was 5/16's" but I was wrong.
