A new speed-timing sensor group is now available. The 273-5041 Speed Sensor Group replaces the 129-6628 Speed Sensor Group. The improved design will enhance the sensitivity of the speed-timing sensor. No adjustments are necessary for installation.Replacing an old non-defective speed-timing sensor group with a new sensor group is not a warrantable repair.
