Powergen or generator decision
I am taking on another project.
This is a 59Y block that has a later 8BA style Powergen mounted to the driver's side head because of the lack of room on the Super Dual manifold for the front mounted generator. The Powergen will hit the hood side panel if the hood is closed. There is also no provision for the fan as it is assembled now. I will be switching to an Edelbrock 1090 intake which will allows for a generator to be mounted in the center. Any suggestions on a generator? I had a converted generator with regulator on my roadster that worked well but I am now thinking the new setups might be better. This will be going back as a 12 volt neg. ground system. Thank you. |

Re: Powergen or generator decision
Powergens suck
I went back to a 12V generator and couldn,t be happier. 6V generator with 12V field windings and a 12V regulator |

Re: Powergen or generator decision
My (expensive!) polished aluminum PowerGen generator-look-alike alternator fried itself after about 2000 miles of light loads. Local alternator shop replaced the guts with something hopefully more reliable.

Re: Powergen or generator decision
If you want to use a Fan on it, the bearings are not made for fan use. An early generator has fan bearings.

Re: Powergen or generator decision
When my powergen died twice on one trip,the rebuilder told me that it used the cheapest GM rectifier and other parts and that the parts don,t like heat.
So then you stick it in a big chunk of Aluminum and wonder why it overheats. Also,mine had a short in the field windings that powergen told me was there since it was new. Great quality control!! |

Re: Powergen or generator decision
i think the early generators have the same bearing as the pilot bearing

Re: Powergen or generator decision
Thank you Steve.
I will try and find the parts to put one together or just get one already done. I appreciate all the input. Thank you. |

Re: Powergen or generator decision
33-38 generators, plus the 39 Standard generator, all have the good Timken tapered roller bearing in the front. These are the only types that can consistently handle the fan load (where the fan blade is directly mounted to the generator pulley). These types may be converted to 12 volt by a shop that knows what they are doing. These early types also have the narrow mounting bracket, so they don’t fit snugly in the 42-48 wide mount intake manifolds. However, that can be remedied.
The 39 Deluxe and all subsequent Ford flathead generators ALL had the regular sealed ball bearing in the front, and this bearing is not adequate to handle a fan load long term. Since none of these models had a fan on the generator, they aren’t desirable unless you’ve got the fan located elsewhere.

Re: Powergen or generator decision
I am running a 12-volt powergen in my avatar - been 7 years and lots of hard miles. Still running good.
That being said, I carry an alternator and bracket just in case it should die. What can I say? I was a boy scout and the be prepared motto has stuck with me .... Lol! |

Re: Powergen or generator decision
I always thought the short 36 gen was the hot ticket for dual carbs with the setback intake. although the current manifold better distributes fuel to all cylinders.

Re: Powergen or generator decision
Another option is to have E.J. Whitney convert your stock style generator into one with good quality alternator parts. I had them convert a 34-36 style generator for my 32 - and I kept it 6V Positive Ground. I wanted more amperage to run halogen bulbs in my headlights, so the stock generator at 16-18 amps would not cut it. Their conversion is not inexpensive, but I've had it on my 32 for a few years and it has been fantastic. They really do a nice job in making the converted setup look almost 100% stock (including what appears to be a "cut out" on top). The case is a bit larger diameter - but nobody has noticed this to date (except me). It is worth checking out:

Re: Powergen or generator decision
You can also convert to a separate fan carrier but you will need a dual front crank pulley. This setup lets you use a stock style gen (or Power Gen) without a fan on it or even a modern style alt (ugly but cheap). I was lucky in that my 59ab came with the dual pulley so it was a simple bolt on after I sourced the parts needed. I am now running a 12V PowerGen. Fingers crossed it holds up, been OK so far. Nice thing is I can carry a modern style alt for a easy to swap backup if the PG takes a dump.

38bill,
Don't forget to oil the fan hub. |

Re: Powergen or generator decision
I need to retro my PG setup to that separate fan mount setup, since it's not deemed reliable.
Is that crankshaft pulley a truck item or something else? Thanks! |
