Note: As this is a Craftsman-sponsored project, you'll notice a number of Craftsman tools in the photos, including Cross Force Wrenches. But here's a secret: we already owned 'em all. They're the same tools we'd have used if they weren't sponsors. Really!
Step 1: Disconnect The Battery
Step 2: Disconnect The Wires
Step 3: Remove The Belt From The Pulley
In our case we grabbed a Craftsman 17mm Cross Force wrench and pushed hard. Normally that would be a pretty painful experience, but the Cross Force was designed for just such a situation. There's a 90-degree twist in the middle of the Cross Force wrenches, so you end up pushing on a flat surface. The result: we could push harder without discomfort. So we just laid into it and the belt came free.
Step 4: Remove Bolts
Step 5: Halfway There
Step 6: Examine The Replacement
Step 7: Reverse The Removal Steps
