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.
