An illustration of the index drive is included in this manual. The procedures in this manual reference the item numbers of this illustration.
OIL SEAL REMOVAL The only repair possible without disassembly of the index drive is replacement of oil seals. To remove oil seals, drill a number of holes into the case of the seal. The seal may then be removed with a pointed tool. Be sure to remove all metallic chips created during the drilling of removal holes. A new seal may be installed as outlined in the "Oil Seal Installation Recommendations" section of the "General Service Manual".
