Refer to Figure 15
Scott Pump Seal Replacement:
The following are instructions for how to reassemble the
pump after it has been disassembled and repaired. Refer
to the parts manual for the components of the pump.
If seal replacement is required:
1. Disassemble pump and clean all components.
2. Assemble the ceramic ring seat of the mechanical
seal (3) into the adapter (4) of the pump. Make sure
the ceramic seat is positioned square into the volute
housing.
3. Clean off any grease or dirt from the pump sleeve (1)
and dry the sleeve so the rubber bellows on the me-
chanical seal will adhere to the sleeve properly when
assembled.
4. Assemble the seal (2) with its spring, on the sleeve by
pushing on the inside rubber portion of the seal using
water as the lubrication. Make sure to align the notch-
es in the mechanical seal with the notches in the
sleeve. Assemble the mechanical seal/sleeve assem-
bly on the pump shaft. The graphite seal face should
touch the white ceramic seat face.
