Tool Mounting Methods
It should be noted that assembly of the tool into the modules will differ
slightly depending on the method used for mounting. If the tool will be
mounted with the plate spacer in place, the tool can be assembled by
following the first set of instructions (A). The reason for the plate spacer
is to allow the tool to be mounted fully assembled.
The tool can also be mounted with a bracket or mounting plate that takes
the place of the spacer. If this is the desired mounting method, the
mounting plate used must be the same thickness as the plate spacer
provided or the tool will not fit together properly. In this case the second
set of instructions (B) should be followed.
Assembly
General Instructions
1. To protect the part's surfaces and to prevent distortion of Housings
and threaded joints, use care when grasping the tool.
2. Always press on the inner ring of a ball-type bearing when installing
the bearing onto a shaft.
3. Always press on the outer ring of a ball-type bearing when pressing
the bearing into a bearing recess.
4. Refer to the "Lubrication" section of this manual for instructions on
how to properly grease this tool.
