a. Remove the travel motor. Refer to Disassembly and Assembly, "Travel Motor - Remove".
Note: Cleanliness is an important factor. Before you begin the disassembly procedure, the exterior
of the components should be thoroughly cleaned. This will help to prevent dirt from entering the
internal mechanism. Precision components can be damaged by contaminants or by dirt. Perform
disassembly procedures on a clean work surface. Keep components covered and protected at all
times.
