Centering and Attachment Screws
Figure 3
It is essential that before tightening bolts the motor/gearbox/seal
assembly center of mass be found and that point used to lift the
seal housings into position. The bolting to the mixer flange should
be complete before the support for the motor/gear box/seal is
removed.
2.1.3 Lower the shaft through the seal cartridge. Great care must be
taken to avoid any binding that may cause the seal hardware to
support the shaft.
2.1.4 When the shaft has threaded through the seal attach the shaft
as required to the mixer drive. Take care to insure that the shaft
is straight and concentric with the bore of the mixer flange. Follow
mixer drive manufacturer re dations.
2.1.5 After the shaft is in its final operating position and no more
adjustments will be made to the position of the shaft, double check
the seal canister and tighten canister bolting to the mixer flange
and/or mixer drive.
2.1.6 Attach the rotating portion of the seal to the shaft. The seal you
are installing is designed to fit your specific piece of equipment.
With this in mind refer to the drawing specific to this seal and your
equipment. Note that there may be small differences from this
instruction in how this step is accomplished. See Figure 3.
