How to Service a Milwaukee Eight Introduction: 37 Step Checklist
Harley-Davidson designated the Milwaukee Eight (M8) as it power-plant for Touring and Softail models.
We are excited to bring you the Milwaukee Eight service videos needed to follow along with your factory service manual. We switched it up a little here at Fix My Hog. Our members asked us to show a video for each specific procedure on the service checklist. Have your manual, checklist for any model or year differences and grab some tools. We might step off the “book” here and there but here are your required service procedures for your Harley M8. We will be posting them all as they come out of the edit process. Click on each title to go to the video.
