e) Align the rotors with the pump shaft so that the large spline teeth on the rotor slide into the missing
teeth on the pump shaft.
f) Place the new rotor cap o-rings into the groove on the rotor caps.
g) Install the rotor caps over the rotor. Rotate the rotor cap so that the hole in the rotor cap lines up
with the threaded hole in the pump shaft.
h) Install the new rotor bolt o-rings into the groove in the rotor bolt.
i) Now thread the rotor bolt through the rotor cap into the pump shaft.
j) To tighten the rotor bolt, place the wooden dowel between the rotors as shown in Figure 18. Tighten
the first rotor bolt with the appropriate wrench to the torque specified in Table A, page 5.
k) Tighten the second rotor bolt, place the wooden dowel between the rotors as shown in Figure 19.
Tighten the second rotor bolt clockwise with the appropriate wrench to the torque specified in Table
A, page 5.

LEARANCES
With the rotors installed, you should check the clearances around the rotor to ensure that the pump
was assembled properly. Use feeler gauges to verify the back and radial clearance between the rotors
and the housing. Use a depth micrometer to verify the front face clearance (see Table A3, page 6). If the
gap is incorrect, please see Setting the Rotor Gap section on page 19 (for the FKL 5, 75,150, 50 &
400 Series) or page 9 (for FKL 50). Rotate
the input shaft to verify that the pump turns
freely. If the gap is correct and the pump
turns freely continue Pump Assembly (below).
a) Install the pump cover o-ring onto the
pump cover.
b) Install the pump cover. Make sure the
threaded end of the forcing screws are flush
with the inside face of the pump cover.
For Jacketed Cover - install the jacketed
cover, replace the jacketed cover o-ring and
then continue with instructions below.
c) Secure the pump cover with the cover nut
washers and cover nuts. Tighten with the
appropriate wrench to the torque specified
in Table A, page 5.
