a100 denso alt ?

anyone converted to denso alt - http://slantsix.org/forum/viewtopic.php?t=28160 -
when i sold the 66 i robbed the alt from my 69 so i could do so - in retrospect i should have either taken money off or had the 66 one rebuilt and put back in - anyway i now have a denso alt per the article - i have it in temp - the article mentions having to shave app 1/8 off the mount - well i have to guess it would be more like a good 1/4" and i dont feel comfortable taking that much off - so what would you do? - modify existing bracket? - make new bracket - the pic included slightly exaggerates the angle and there is clearance between pulley and fan -
2nd - would this off align cause low idle low charge - that is at a low idle i measure app just under 13 - any higher idle or operation and up to app 14.3 - oo3

[iOffset =will not effect the charging rate- space the fan out ( behind the Black pulley) as needed-or- make a new bracket?

If he spaces out that black pulley, won't the fan be dangerously close to the radiator? For another $100 or so you could get a decent one wire alternator (Powermaster or similar) and bolt right on?

Plus wouldn't that throw off the belt alignment with the crankshaft? I agree custom bracket... might also have to shave a bit off the lower ear on the alt.

[i]from the pics - we cannot tell how much offset is there ???? As stated -looks worse than it is -so How much space is available or needed?? Many -cannot afford to have the cash layout from time to time? I do agree a proper alt & bracket would be the solution-yet always look for the lest expensive ways to do the mods. Working with whats available & can be done the easiest?? =Happy Vannin

I would prefer to grind on the alt. rather than the bracket.
You can find a replacement alt, but those brackets are tougher to find.
Did you update all the charging system wiring and components to handle double or triple the output? Did you include circuit protection so if/when something happens, it won't catch fire?

if i take a 1/4" off the alt mount thats maybe 1/2 of the mount - i dont feel comfortable with that - i may be wrong - that would be probably the easiest solution - i could make up a bracket or i thought of widening the mount slots on existing bracket, but i also dont really like the thought of modifying the only bracket i have - the wiring has been updated as a po put in a electronic ign and put those components and a solid state reg etc in a box behind the drivers seat - i would have to look closer to see what kind of wire etc was used - yes i should have additional circuit protection - and i will - however i would prefer a fuse or circuit breaker rather than fusible link - i really think this could be a viable alt and they are plentiful in junkyards - i had planed on doing away with the amp meter at some point anyway - prefer a volt measure - oo3

denso alt in and aligned - and was able to adapt tension-er -

I have recently been looking into alternators for my slant 6 as well. I pulled the bad motor from my project and removed the alternator. After reading posts, I inspected my bracket and noticed it had been modified by the PO. I can see a few weld spots on it. There is a small crack that i'll have my (welder) buddy take a look at. I checked the alternator that came from the original motor. It was not the stock. I checked the numbers on it and found 3438180. An internet search revealed it's application to be from a 70's + mopar and 60 amp. Autozone was able to find the number and has them in stock and theirs is rated at 65 amps. I mocked up the old alternator and bracket to the rebuilt slant 6 on my stand and the pully matched up perfectly. I guess i got lucky. The alternator i have now is a single pully, but AZ stated that theirs is a double. My rebuilt motor came from a 70's barracuda and has 3 pullys on the crankshaft, more than I need. I'm thinking that if I can pull this off, i'll use 2 belts to my alternator. (I'll be running an electric fan with the new FSR radiator i'll be getting soon, so I wont have any fan clearance issues, knock on wood)

OK. just got back from AZ and the alternator they had on the shelf was a new design with double pullys. We looked a 2 different styles with double pullys and they did not align. I ordered the 50 amp that their system called for with the single pully. In the meantime, can anyone provide a part number that I can use. I'll keep checking around. thanks
(they tested my alt and it was bad)

the denso alternator pulley looks to be a larger size than what a stock 50 or 65 amp alternator would have. that will cause a low charge situation at idle as it spins slower than normally would.bigger pulley on alternator should take longer to make 1 revoultion than stock.

I just measured the pully on my bad alternator and it's a 3 inch. AZ said their system does not show the pully diameter, so i'll have to see it when it arrives. very good point about the diameter. I just happen to run into a local guy at a swap meet that has an alternator/starter rebuild shop. Maybe someone is trying to send me a sign. lol
