EXCERPT:
Disassemble & Assemble Final Drives
Start By:
a. remove final drives
1. Thoroughly clean the outside of the final drive prior to disassembly.
2. Remove the travel brake valve and the travel motor from the final drive. See the topics "Remove & Install Travel Brake Valves" and "Remove & Install Travel Motors" in this module.
3. Put an alignment mark across the sections of the final drive for assembly purposes. The parts must be reinstalled in their original locations.
