  • Generator Pulley

    Started putting the generator back together after detailing it, correct bolts etc i bought a Generator pulley bolt from Brattons, the description says that the 30-31 generator takes the big headed black bolt and black star washer......but in trying to put the pulley back on with the new bolt and washer, the bolt isn't long enough. The generator i rebuilt is period correct for the A there a different pulley?????? everything i read says no....when i put the pulley on the generator it bottoms out and hits the split ring that is right before the housing.......isn't this supposed to be a wedge fit??? not sure what to do, is they pulley wrong/wore out or the shaft on the generator bad???

        I bet he just turned the pulley around and placed the spacer where it belongs.

          LOL OK OK In READING not skimming the judging standard books there IS a long taper pulley (Type 4) from June 29 to march 30 and then there is a short taper pulley (type 5) from April 30 to the end I have the long taper pulley not the short thats why the bolt will not start!!

              The bolt size also changed when the length of the taper changed in March 1930. Be sure to buy a longer bolt to thread to the bottom of the threads when you use a puller or hammer to tap the pulley loose. I've seen way too much damage done to the armature taper by pressing or tapping against it. I keep a 1/4 x 1 1/2" fine thread bolt, and a 5/16 x 1 1/2" fine thread bolt handy to press against when I remove a pulley or bearing.

                Is a "Generator Tension Brace" allowed and if so is the metal painted of left unfinished
                Is the generator pulley painted if unfinished cast. (1931 cast pulley

                generator armature taper differences
                by thom
                I took the generator off of our '28 Coupe to the local shop to be repaired, and the guy is experienced in Model T & Model A generator and starter rebuilds but he ask me a question that I could not answer so I will ask it here.
                Will Model A generators with the two different tapers interchange if you use the complete generator, pulley included? The armatures will not interchange from one...

                Generator for idler pulley
                by w.michael
                I am preparing to run an engine on a stand. I need to use a generator to tighten the belt so the water pump will work. I don’t want to wire the generator into the circuit, or ground it. If I take the brushes out, will the generator run without burning up? Or do I need to disconnect something else in the generator? I want to keep this extra generator as an idler pulley to run on the engine stand...

                Does anyone know the correlation/formula for engine to generator rpm?

                Alternator to generator

                If a person wanted to change their car back as it would have been originally, with a generator, what would you have to do to make it correct? We have a new alternator now on the car & have access to a couple generators. Thanks...

                After market generator
                by Rob B
                I have an aftermarket short nose generator on my 30 model A. When I loosen the bracket to create slack in the belt, the generator hits the engine block. So, it isn’t loose enough to get the belt off. Any suggestions?

                Name That Generator
                by gdaquilina
                This is the generator that was on the car when I received it in 1993. It has performed well, and I am trying to determine its origin. It has the oilers at both ends and two wires coming from the grommeted hole where the stud to the cutout is usually found. One of the wires is connected to the cutout, the other is a ground to the one of the cutout screws. The pulley is two piece, riveted together,...

                Generator Output Issue - Resolved
                by 01A
                I wanted to share an experience with the no output issue I had with the generator that has a stock cutout. The ammeter needle was not showing a charge. Referencing some ideas from this forum I tried jumping the cutout while increasing rpm's to rule out a bad cutout, but no improvement. Then tried motoring the generator. The generator motored just fine. What I eventually found was the generator output...

                Generator question?
                by rusty
                Does anybody know what this generator setup is? Looks to me to be an aftermarket bracket to adapt a later style generator? Or could this be for the Model B? Doesn't look right to be Model A.

                Generator Cut-Out Wiring
                by chiefc73
                Good afternoon - I believe I know the answer to this already after scouring the forum but just need clarification, the three wires running to the Generator Cut-Out hook up to the Battery Side Terminal - Correct? Reason why I'm asking is my generator has a Nu-Rex Positive Ground Cut-Out and all the wires are running to the Generator Side Terminal. Not sure why it would be hooked up this way?
