Hey guys, I pulled my starter today off of my '44 B. It has worked very intermittently and now it won't do much more than a weak bump. The 6v battery was replaced and the starter is still not operating. Here are pictures of the starter taken apart. Can someone please tell me what I should be looking for? http://s34.photobucket.com/user/Catchrmnmatt/media/IMG_7159.jpg.html" rel="nofollow">  http://s34.photobucket.com/user/Catchrmnmatt/media/IMG_7158.jpg.html" rel="nofollow">  http://s34.photobucket.com/user/Catchrmnmatt/media/IMG_7157.jpg.html" rel="nofollow">  http://s34.photobucket.com/user/Catchrmnmatt/media/IMG_7156.jpg.html" rel="nofollow">  I found this kit, https://www.ebay.com/p/AC-Allis-Chalmers-B-Ca-WC-Wd45-Delco-Starter-Repair-Kit-6-Volt-Brushes-Bushings/1232970907?iid=190824067754&chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=190824067754&targetid=539174358435&device=c&mktype=pla&googleloc=1013500&poi=&campaignid=1881946464&mkgroupid=70435645632&rlsatarget=pla-539174358435&abcId=1139336&merchantid=8187854&gclid=Cj0KCQjw2K3rBRDiARIsAOFSW_7m3NLNzoAodDlR5sg-11leuuvZk29A2rKkTWxXHAPUDjprDIgCP7waAtWmEALw_wcB Would it be helpful swapping out these parts?

I'm no expert but the brushes look good. think the kit would be a waste of money. The burning/pitting on the external stud may be more of the problem. I would clean and tighten all cable connections especially the ground before doing brush's and bushings |

10 outta' 10 Starter motors that come in my shop for rebuild have bad Armatures in them. That is the heart of the unit. When I rebuild a customer's unit, it gets either a new or rewound arm in it no matter what. Those mechanical switches are as bad as the pinch bolt design that holds the starter in the bellhousing. When those switches get worn (like your's looks in the pic) its time to renew the switch or incorporate a starter relay where there wouldn't be any voltage drop in that area to start the engine. You could then move to a key crank start mode.. HTH Steve@B&B ------------- 39'RC, 43'WC, 48'B, 49'G, 50'WF, 65 Big 10, 67'B-110, 75'716H, 2-620's, & a Motorhead wife |

File that copper nub on your starter to get rid of pitting and that black crap. Then either get a new switch of file the one you have so you have good contact all the way across all 3 points. If that doesn't help, send it to Steve for a rebuild. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

I know electric start is convenient, but all the time I owned a B, I started it with the crank, of course it didn't have a starter or a generator or a battery  ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Listen closely to what SteveNJ says. He is our resident electrical expert. I know when we sold them we always had some trouble with the B-C starters. In fact, we used to put a bearing to support the armature near the gear. Seemed to help. Course that was in the 40's - 60's and tractors were newer then. Take good care of my favorite. Good Luck!
