Maintenance and Lubrication
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.
5. Assemble the impeller, being careful not to jar the me-
chanical seal that has been positioned on the pump
shaft.
6. Assemble the rest of the pump.

Scott Pump Seal Replacement
Scott and Ace Pumps
The centrifugal pump is designed for long life and service.
Through the years, there may be a need to replace the me-
chanical seal or service some component of the pump. A
mechanical seal may weep slightly, but if it starts to drip,
the pump will have to be disassembled. Before disassem-
bling the pump, be sure to wash it out with fresh water.
If the pump is leaking, before removing it from the sprayer,
run the pump with adequate water in the tank to diagnose
the actual pump problem.
Refer to Figure 24 for 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.
