1. Remove the Mow-Ball™ Support Assembly. See “Removing the Mow-Ball™ Support Assembly” on
page 31.
2. Remove the Bottom Shield. See “Bottom Shield” on page 34.
3. Remove the Trimmer Head Belt from around the Engine Pulley. There is enough slack in the Belt to
just peel the Belt from around the Pulley.
4. Grasp the Transmission Housing and rotate it out to loosen the Drive Belt (Figure 28). You can now
remove the Belt from the Transmission Pulley and upper Engine Pulley. The Transmission Housing
is spring loaded so it will return to its original position when released.
5. Install a new DR Drive Belt around the upper Engine Pulley, rotate the Transmission Housing out,
and slip the Drive Belt around the Transmission Pulley. Allow the Housing to return to its resting
position with the Belt in place.
6. Re-install the Trimmer Head Belt on the Lower Engine Pulley.
7. Re-install the Bottom Shield and the Mow-Ball™ Support Assembly.
