4. Turn the micrometer nuts (66) alternately, counting the
number of radial lines passing a fixed point on the bearing
cartridge flange. By turning the micrometer nut from one
radial line to the next, the impeller will move by 0.003 in.
(0.08 mm). The clearance required between the impeller
and the suction side of the casing will vary with the
temperature of the liquid being pumped as shown on the
following page:

Up to and including 100°F (38°C), set impeller
operating clearance at 0.015 in. (0.38 mm).

For every 50°F (28°C) above 100°F (38°C), increase
the operating clearance by an additional 0.002 in.
(0.05 mm).

Remember, each line represents 0.003 in. (0.08 mm),
so a 0.015 in. (0.38 mm) operating clearance will
require you to turn the micrometer nuts (66) five radial
lines.
NOTE:
For Vortex pumps, loosen the micrometer nuts (66)
approximately 15 lines of 0.003 in. (0.08 mm) each which
provides a clearance between the impeller and back cover of
0.045 in. (1.14 mm).
5. Tighten the lock nuts (404) evenly and alternately against
the cartridge (33) flange. Make certain the micrometer
nuts (66) do not move while this is being done. Use two
wrenches, one to hold the micrometer nut (66) the other to
tighten the lock nut (404). For Vortex pumps, tighten the
locknuts (404) until the cartridge is tight against the
micrometer nuts (66).
4.5 Set Mechanical Seal
After setting the impeller operating clearance, the mechanical
seal (80) can be adjusted and securely fastened to the shaft.
Tighten mechanical seal gland nuts per the torque
specification in section 11. For information on mechanical seal
installation, refer to the instructions accompanying the seal.

Modifications Required
The base, motor, and coupling may require some modification
before proceeding to install the new System One Power End
Conversion. Various options are available to use the existing
baseplate with the conversion power end.
Please contact the factory if there are any questions regarding
the appropriate procedure.
