Maintenance (Continued)
11.Remove the intermediate volute
and slide the impeller spacer off of
the shaft.
12.For Model No. 4RJ96A, repeat Steps
9 through 11 for the second
intermediate volute.
13.Remove the impeller. Don’t disturb
the shaft keys if you are only
replacing the seal.
14.Rotate the seal spring retainer cup
so that the slot lines up with the
shaft keys; remove the cup and
spring.
15.Remove the two cap screws holding
the adapter bracket to the motor.
16.With two screwdrivers on opposite
sides of the pump, carefully pry the
pump adapter away from the
motor. This will pull the seal off of
the motor shaft.
NOTE: Use caution to make sure
that the ceramic seal does not dig
into the shaft and scratch the
shaft’s sealing surface.
INSTALLATION OF NEW SEAL
1. Clean all gasket surfaces thoroughly
before reassembly. Clean the seal
bore cavity in the pump adapter.
2. Wet the rubber seat ring with soapy
water and push the stationary part
of the seal into the seal bore cavity.
Use a piece of 1” pipe pressing on a
cardboard washer (to prevent
damaging seal surface) as a press.
Make sure that the seal half is fully
seated in the seal bore cavity.
Remove the cardboard once the seal
is in place.
3. Make sure that the shaft keys are in
place on the shaft. If they are not,
squeeze them in place now with slip
joint pliers. Do not tap them or hit
them with a hammer; you could
bend the shaft (See Figure 16).
When the keys are correctly
installed, the adapter will pass over
the keys without interference.
4. Carefully slide the adapter over the
shaft (See Figure 17).
NOTE: Do not damage the shaft
sealing surface; it is highly polished
and any slight scratches or nicks will
ruin it.
5. Using the alignment marks made
before disassembly, line up the
adapter with the motor and bolt
the adapter in place. Tighten the
cap screws evenly.
6. Push the shaft seal and seal spring
onto the shaft, after making sure
that the seal faces and shaft are
clean. Take care that the shaft
shoulder does not damage the
carbon seal face. Follow the seal
spring with the spring holder;
compress the spring and give the
spring holder a quarter turn to lock
it under the first shaft key (See
Figure 18).
