There is a locating pin in the back of the seal housing that
must align with the notch in the back of the seal seat.
To aid the installation process and prevent damage to
the seal seat, we recommend using a plastic handle
screwdriver. With the notch facing up, lubricate the
seal seat with light oil or spray lubricant and place
on top of the plastic handle screwdriver. Place the
seal housing over the seal seat and visually align the
locating pin with the notch in the seal seat.
Tap the housing down with the palm of your hand to
secure the seat in the housing.
If the pin is misaligned during the process, you may
use a small screw driver to align the notch of the seal
seat with the pin. Again, tap the seal housing down
with the palm of your hand to make sure the seal seat
is secure.
27. Reinstall all the metal shims, that were removed during
disassembly, behind the flange of the seal housing.
Slide the seal housing over the shaft and press into
the pump casing. Make sure the seal housing slides
through the O-ring and is seated to the back of the
pump casing. To confirm the seal housing is seated
completely, you may lightly tap the outer flange surface
on the front of the seal housing with a screwdriver. Do
not tap on the seal seat located inside the housing.
28. The seal assembly will need to be assembled before
it can be installed in the seal housing. Remove the
carbon from the retainer and apply lubricant to the
inner O-ring. Place carbon back on the retainer. Align
notches on the retainer with locators on the spring seal
assembly and press into place.
