Hello any one using a 1967 Dodge Dart 12V Alternator on there Flat Heads if so would like pictures of how its mounted if so thanks
Just because one is lying around isn't a good enough reason to use it. I'm pretty sure they were Autolite and require an external voltage regulator to be mounted and wired. Lately I've been seeing a lot of small Japanese car ones. They are about 1/2 the size of a GM one wire. https://www.ebay.com/itm/3035181725...sXIWxCGB1NSuxHGLOCX9z75qOE|tkp:Bk9SR7yBxZn6Yw
I used a Mopar alternator on my 331 Hemi with the small regulator. On my '58 230 Dodge flathead in my '36 Dodge Pickup I used a single wire GM alternator on the original generator mount and used a section of 1928-9 Model A head;light bar for a bolt spacer! All 3 of the Big 3 manufacturers on 1 vehicle! Both work fine. Dave But wait! You didn't specify what brand of flathead!?
I had to build my mounts, but there's a Nippon Denso 65 amp being spun with a V-belt on my slant 6. And that came off an '80 Toyota Corolla in a salvage yard. Roger
These work really well, easy to get the pulley off (with a rattle gun) and change to 5/8 if you need to.
Same unit fits 60/69 Mopar that isn't loaded down with amp eating accessories. Two things, How do you plan to mount it and do you need to change to a 5/8 pulley? As Acme30 said, the pulley swap is simple if you use the correct tools, hard a hell if you are a fool who doesn't. Impact wrench for the nut and the correct pulley puller to pull it off. That could be a pay the deposit for the set at the parts house, Use it, return it to get the deposit back deal. Vintage auto Garage sells a 5/8 pulley for 20.00 or a shiny one for 30 and in that gas hog truck that I drive it take more than 20 bucks worth of gas to get to the closest place that might have one. You have to know the Bore though. You might talk to an alternator/starter/generator shop on that one. Delco 10 or 12 Si alternator is a lot easier in that respect as a lot of older farm equipment uses 5/8 belts and folks swap alternators on to them all the time. That was the original purpose of a one wire alternator too. Farm tractors that either had magnito ign or were diesel and didn't have a battery ignition system to run the exciter wire off. Add in that the external regulator is a simple hookup.
How are you using a rattle gun to get the pulley off? I can’t seem to get the proper image in my mind. I ***ume you’re speaking of an air chisel? Or are you referring to an impact wrench to get the nut loose? Age is a terrible thing…
Sorry impact gun is what I meant. And I was referring to the Denso type which have a nut holding the pulley on.
The largest stock pulley for that alternator was on Dodge trucks and was 1/2 inch belt. It was a large diameter double pulley which is not the best at idle for charging, especially on a lower rpm engine like a flat head. The pulleys are a ***** to change if you don’t have the right equipment and the alternator has to be torn down to press on the new pulley. In my humble opinion not your best choice, I spent 40 years as a rebuilder if that helps you understand my opinion.
For the look and fins I once hung one on a'58 Chevy. Luckily the man at the yard told me to take the little box that the wires ran to.
