the cover from loosening during operation.
After assembling the cover per the procedures
in 4.3.5, install the setscrew in a new location
per the following procedures.
4.3.6.1
At the cover/housing interface, drill a #21

Tap the hole using a #10-32 NF-3 bottoming
tap. Remove any debris from the hole.

Apply Loctite #242 to the setscrew (11),

installed flush or below the surface of the
housing after assembly.

sealing rings (12), each with a different
cross section, for mounting the rotorseal
to the shaft. Select the ring that matches the
groove in the mounting flange of the housing
