SETTING UP THE MESHING TOOL
1. Make sure the set screws are installed on the meshing tool. If they are not installed, install them without passing
through the inner cutout of the tool.
2. Install the meshing tool with the U-Joint Removal Tool (T/N OTC7248) or universal 6-inch C-clamp. Hand tighten
the set screws with a hex tool.
NOTE: If you are using a 6-inch C-clamp, the foot of the C-Clamp must be 1-inch in diameter for the meshing tool to
fit correctly.
