  • Ford guys question
  • Pulled one of the 9nís in the barn tank is gummed up. Has cm hall lights. Went to remove the hood and found the dog legs are the ones with no holes. Generator is the one wire with the high and low screw. Havenít checked the year. Just thought it was interesting. Have a few 9 or 2nís that has the hole in the dog leg for the choke cable. I Ďm not sure how I over looked this stuff over years. When did the change to the dog legs with the holes in them?

  • HiYa Wayne-
    What do you find interesting? The CM HALL headlights were used until about 1943 or so, logo gad "TRACTOR-LITE" on clear lens, then FORD supplied the lights, with their logo "TRACT-O-LITE" but still with separate bulb and reflector. In '44 the sealed beam headlamp was introduced to the world and Ford then switched to them. The 'holes' on the doglegs are often called the smooth type doglegs. They were changed to the bolt on type as well as the change from the cast iron support with the release of the 2N Model. Contrary to some, the 2N Model was not put into production until October, 1942, and those were the War-Horse models on steel wheels and a magneto. War-Horse models lasted only for a few months and by April, 1943 were back to normal 2N production with electrics and rubber tires. Your generator would be either the 9N-10000-C or 2N-10000. Both were 11.5 AMP, 1-Wire/3-Brush, A-Circuit type w/3rd brush adjusting screw on the back panel. The difference would be that the 2N now had an OEM belt tensioner fastened to the barrel. The 9N offered a kit with a steel band to wrap the tensioner onto. The kit did not fit on the 9N-A or 9N-B generators their barrels were much smaller in diameter. Up until then the was no belt tension support other than the pivot mounting bolt and it would loosen itself up in the field and if you didn't stop every hour or so and re-tighten the fan belt, your battery would be dead by the end of the day. All 9N's and 2N's used the round-can cutout circuit except for the first early 9N's which used a rectangular voltage regulator with a 'B' Circuit design, at 7 AMPS and a 2-Wire/2-Brush style. Ford was constantly mucking with charging systems. It took the 2N to figure out the belt tensioner was needed. Ironic that when the NAA was released they reverted back to the B Circuit design. The generators were changed back to a 2-Brush type in early-to mid-8N years and used a voltage regulator but were 20 AMPS. Probably more than you wanted to know but, hey you asked...

  • I think the dogleg change was made same time as the 2n axle carrier. I think it was about 167488

  • Thanks Tim . I knew some of this stuff but I forget most. Gets confusing. I knew they used parts until gone. Didnít know if some guys liked those old generators? Sold spare of plain doglegs to a guy and he was just going to drill holes in them. He didnít care. Thereís more stuff I donít know than what I think I know. Have a great day. Love this stuff. Even if I cuss it sometimes. Lol
