Verify that further disassembly is
necessary if:
•
The impeller nut and locknut are not
secure.
•
The impeller has to be replaced or
requires a major cleaning.
•
The center housing has to be
replaced. Remove it by following
steps 4 through 6. However, if a
complete pump disassembly is
required, temporarily reassemble the
impeller housing and end casing with
three or four tie-rod nuts.
Then invert the pump and continue with
steps in DE Shaft Seal on page 21.
4. Loosen and remove the impeller locknut. Then
loosen and remove the impeller nut (thin nut).
Note the threading:
KLRC-40 and 75
KLRC-125 to 950

CCW to loosen
5. Lift off the impeller and note the direction of the
blade for reassembly.
6. Remove center housing by disassembling tie-
rod nuts at the DE end casing.
DE Shaft Seal
1. Position pump vertically on support stand,
DE up.
2. Remove DE bearing housing cap and bearing

DE Stage
1. Remove the crossover pipe at connecting

2. Remove the DE tie-rod nuts and lift off the DE
end casing. Remove the end plate from the
end casing only if it needs to be replaced.
3. Remove the impeller housing.
4. Remove shaft locknut and impeller nut. This
step is identical to step 4 in
NDE Stage on
page 20
except nut threading is in the
opposite direction on this end of the respective
pump models:
KLRC-40 and 75
KLRC-125 to 950

5. Remove impeller and note direction of blade
for reassembly.
Center Housing and NDE Stage
1. Remove NDE tie-rod nuts and lift off the center
housing with both sets of tie-rods.
1. Lift off the NDE impeller housing.
2. Lift the shaft with NDE impeller attached from
the NDE end casing.

impeller locknut is not securely fastened and
indicates fuller inspection, or if either part
needs to be replaced.
