The drive gears of the two-brush generators used on Harley-Davidson V-twin models from 1958 onward are secured with a nut. In addition to being positively located on the shaft, this design also transfers the drive force via the oil slinger to the right armature bearing.
Generator Gears
Generator gears have either 13 or 14 teeth. All models used 14 tooth gears through 1957. The 1958 to 1969 Panheads and Shovelheads used a 13-tooth gear.
All of the 45’s, K models and Sportster use a 14-tooth gear. 45’s require a built in slinger. The gear mesh on 1957 and earlier models is adjustable. It may be possible to use a 13-tooth gear if the proper gear mesh can be achieved. This will increase the low speed generator output by 66%.
On three brush generators (→1957 the gear is held on with a roll pin. These gears have a hole for the roll pin. On a two brush generator (1958→ the gear is held on with a nut.
