: : I am trying to convert my 8n to 12 volts. I have found a 12 volt alt. from a Gm. The mounting bracket from an old buick v-8 Fit with a few modafications. My problem is the pulley on the GM. alt. is smaller in width than the pulley on the stock generator. Will this cause a proble with the belt ? Do I need to change the pulley or do I use a different belt? Any help here would be wonderfull. Thank you in advance Jim aka Wilseya. : : You can e mail me at lybarger@thegrid.net : : Thanks again and Wilseya : The V-belt has to fit all pulleys or it will be destroyed and won't work while its being destroyed. You probably can't use the old generator pulley on the alternator because the alternator needs to turn faster and the tractor already runs slower than a car engine. Its a lot easier to change the new alternator's pulley than to change the crankshaft and water pump pulleys. You may have to visit a machine shop and have a custom pulley made to match the width and angle of the ford pulley but the diameter of the standard alternator pulley. You might be able to separate the halves of the alternator pulley with washers, if the shaft is long enough. : Gerald When I converted my tractor to an alternator I went to an alternator repair shop and they gave me a smaller pulley from their "junk" pile. They usually have alot of old ones laying around. Good Luck!
