Hi — Just get another used generator in good shape , not rusty ? commutator does not “go “ but i know if generator is badly overheated it can toss solder that holds the winding wires to it . Such an armature is junk . changing a commutator or rewind is a huge job not really practical in 2025 . And not as good as a stock one just needing cleaning up If blackened due to driving after end of brush life or stuck brushes ( sparking etc ) that can be cleaned up . I honestly think if you were told “it needs a commutator” go someplace else . All mopar 30- 35 A generators are essentially the same electrical parts despite obsession with part numbers . The variations involve clocking of end plates and variations in mounting flanges ( you can use F ends / mount parts ) and pulleys ( 1 or 2 groove) A dodge or plymouth can donate — sometimes you do see replacement 12 v armatures on ebay. 57-61 12 v What does go are the brushes , easy to change wear item , ~ 80 k miles, low cost , and sometimes bearings in the end plates . Brush springs can rust or brushes can stick in slides . That blackens commutator , can be polished . No need to undercut just clean out slots between bars with box cutter ( dont slip snd scratch it) If AC , it gets harder , more powerful generator 35-40 A are rare . At one time i routinely put alternator in F , but now such a special valuable car , keep stock ? Generators worked fine , for 70 k still do ! Genernator are big ( huge!) bucks , weird one off things — no parts if it punts . Great for Ford model A going to 12 v etc. Any non stock thing ( alternator ) involves harness changes will look non stock on firewall too just mho On Jan 15, 2025, at 7:57 PM, dplotkin@xxxxxxxxxxxxxxxxxxx wrote: -- For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang --- You received this message because you are subscribed to the Google Groups "Chrysler 300 Club International" group.
