Why waste your hard earned money on a 'new' Chinese made generator when all you need to do is take your existing one to a starter/alternator shop and let them rebuild it. Don't have the original? I'd buy one on fleabay, and then get it rebuilt -still cheaper than teh new junk models out there and you end up with a much better quality part. There should be two mounting brackets on the Ford N generator. One is the front end plate where the armature shaft comes out and the pulley installs to. The other is bolted to the barrel itself. Now the flawed design in the early Ford generator mounting method using only the mounting pivot bolt to hold in place was replaced with the 2N-10000 unit which had the two 1/4-28 tapped holes on the barrel which held a small bracket and the tensioning bracket. A third piece was bolted to the nearest head stud to receive the spring-loaded bolt/tensioning rod. This kept the tension of your generator at a constant so it didn't loosen up and cause slack in the belt which then would fail to charge correctly. Ask any old time farmer who used the early 9Ns and 2Ns. They would have to stop the tractor every few hours to check the generator tension and retighten the pivot bolt otherwise by the end of the day they'd be stuck in teh field with a dead battery. Dealers sold a kit for the earlier 9N generators that had the tensioning bracket and a band to fit around the barrel as those barrels were a smaller diameter and did not have two tapped holes. Just my opinion, but I'd do a rebuild on the original rather than buying 'new'.
