seal. Anything beyond this will require repairs to the motor, which are beyond the scope of
these instructions. Check motor fan and shroud for damage and clean, if necessary.
Motor and Pump Assembly
Assembly Procedure
The PowerSoak pumps are easy to put together. The hardest part, requiring the most care,
is installation of the mechanical seal parts.
Study the exploded diagram and become familiar with the name of each part. The diagram
shows the relative order of assembly, but also READ THE FOLLOWING
INSTRUCTIONS.
1. Make sure all of the parts are clean and ready for assembly. This means no dirt or
pieces of old gasket in the joints between the motor, adapter, and casing. Make sure the
parts around mechanical seal are clean. Dirt and misalignment will ruin a mechanical
seal.
2. Install the shaft sleeve o-ring in the place against the motor shaft shoulder. Don’t
let it be cut by the sharp edges of the keyway.
3. Push the mechanical seal seat squarely in the adapter. Use fingers only. A little
liquid soap (or light oil if soap not available) can be wiped on the outside of the seat
ring to make it slip easily into position. Don’t let it be cut by the edges of the adapter.
Don’t install the adapter on the motor face yet.
4.
Check the shaft sleeve fit on the motor shaft. It should slide easily into place. If it
doesn’t, find out why. Do not try to drive the shaft sleeve onto the shaft with a
hammer. Check to make sure there are no score marks or scratches on the sleeve.
5. Install the adapter and tighten the cap screws, which hold tit to the motor face.
6. Remove any dirt particles and coat the lapped face of the mechanical seal with
clean SAE 10 or SAE 20 oil. DO NOT USE GREASE.
7. Slide the shaft sleeve on the shaft so that it covers the shaft sleeve o-ring and butts
against the shoulder.
8. Coat the shaft sleeve lightly with liquid soap (or light oil if soap not available).
