8. Press the new cartridge into the recess in the adapter. A sealing compound
(such as silicon or Permatex) may be used to assure a water tight fit on the
outside of the cartridge.
9. Wet the rubber portion of the ceramic seat with a light coating of soapy
water.
10. Press the seal seat squarely into the cavity in the impeller. If the seal
seat does not press squarely into the cavity, it can be adjusted in place
by pushing on it with a piece of pipe. Always use a piece of cardboard
between the pipe and the seal seat to avoid scratching the face of the seal
seat. This is a lapped surface and must be handled very carefully.
11. After the seal seat is in place, check that it is clean and has not been
scratched or cracked.
12.
Mount the adapter on the motor mounting face making sure the seal flush
part is approximately in the 1 o’clock position when facing the pump.
13. Replace the impeller and tighten, make certain any shims (Ref. No. 12)
previously used are in place.
14. Place the o-ring seal on the adapter and replace the casing. Replace and
tighten the cap screws.
15. Before proceeding to replace the fan and fan guard, turn the shaft to make
certain the impeller turns free and is not rubbing the casing.
16. If the shaft turns free replace the fan and fan guard. If it rubs the casing
follow steps 1 and 2. Remove any shims from the shaft and reassemble
following steps 13 thru 16.
SHIM ADJUSTMENT
When installing a replacement impeller (Ref. No. 13) or motor (Ref. No. 1), it
may be necessary to adjust the number of shims (Ref. No. 12) to ensure proper
running clearance between the impeller and the casing. Proceed as follows:
NOTE:
A proper running clearance is less than 0.010”.
1. For impeller replacement, add one 0.010” shim in addition to those
removed originally.
2. For motor replacement, add two 0.010” shims in addition to the shims
removed during disassembly.
3. Reassemble the pump as described in steps 13 thru 16.
IMPORTANT:
Be sure that the casing is snugly in place and check the shaft to
make sure it is turning freely. If it turns freely, check to be sure that the adapter
and casing are fitted tight together. If they are not, tighten the fasteners (Ref.
No. 2) and recheck the shaft for free turning. Tighten carefully, turning the shaft
while tightening so that the motor bearings are not damaged in the event that
too many shims were installed. If shaft seizes before fasteners are completely
tight, disassemble the pump and remove one shim and repeat reassembly.
