View Full Version : Magneto drive gear ID solved.

03-17-2005, 02:12 AM
The magneto drive box that attaches to the primary on a Scout (ear shaped thing) has a primary (double) gear that engages or is driven off the primary chain. This 22 tooth gear engages a secondary gear that has 44 teeth. Turns mag at half engine speed. The 44 tooth gear ID is beveled and keyed.

The Chief secondary gear is simular in appearance but -40 toothed and has a smaller outer diameter and exit/mount boss.

A big thanks to all that helped me figure this out. Now I just need a cover for the box!
