No. I converted to a single wire 12 volt alternator and did not have to change the pulley on the fan assembly or the alternator. It is possible that you will need to exchange the pulley from the generator to the alternator.Tractorboy3 wrote:do I need to change the pulley on the fan assy?
Advisable to change the amp gauge. Most alternators put out 60 + amps. The original IH gauge on the Cub was 20 amps.can I use the existing charge /discharge gauge.
