Parts List; Spare Parts - Grundfos CR Installation And Operating Instruction Manual

4. Lubricate the coupling screws with an anti-seize and
lubricating compound. Tighten the coupling screws (finger
tight) while keeping the coupling separation equal on both
sides and the motor shaft keyway centered in the coupling half
as shown in fig. 16.
5. When the screws are tight enough to keep the couplings in
place, then torque the screws evenly in a crisscross pattern.
6. Torque coupling screws to 62 ft.-lbs (75 and 100 hp motors to
74 ft-lbs). Remove the adjustment fork from under the
cartridge seal collar and replace it to the storage location; see
fig. 21.

7. Check to see that the gaps between the coupling halves are
equal. Loosen and readjust, if necessary.
8. Be certain the pump shaft can be rotated by hand. If the shaft
cannot be rotated or it binds, disassemble and check for
misalignment.
9. Prime the pump.
10.Follow the wiring diagram on the motor label for the correct
motor wiring combination which matches your supply voltage.
Once this has been confirmed, reconnect the power supply
wiring to the motor.
11.Check the direction of rotation, by bump-starting the motor.
Rotation must be left to right (counter-clockwise) when looking
directly at the coupling.
12.Shut off the power, then re-install the coupling guards. After
the coupling guards have been installed the power can be
turned back on.

11. Parts List

For each CR pump model Grundfos offers an extensive Parts List
and diagram of part used in that pump and is recommended to
have on hand for future maintenance. In addition, the listings also
provide information about prepackaged Service Kits for those
pump components most likely to exhibit wear over time, as well
as the complete Impeller Stack needed to replace the "guts" of
each model. These Parts Lists are available separately from the
Grundfos literature warehouse or as a set with extensive service
instructions in the Grundfos CR Service Manuals (for a small
charge).
