Changing Rotation:
Looking at the pump from the shaft end with the ports up, locate the short vent plug
(painted red). This is the suction (inlet) side of the pump. If on the right, rotation is clockwise; if
on the left, counterclockwise. On the opposite side is a long vent plug. Remove both plugs and
interchange locations.

If outfitted with an internal relief valve (model CK1BV), the rotation cannot be changed in the
field unless the cover/valve assembly is also replaced.
To change the location of the suction port on pumps supplied with Tuthill's unique automatic
reversing feature (model RCK1B), the following must be done in addition to the steps above:
•
Remove the cover screws.
•
Rotate the cover 180° so that the boss on the cover points to the new suction (inlet) port.
•
Align the mounting holes and reinstall the cover screws.

Disassembly and Seal Replacement:
•
Remove the internal relief valve and gasket assembly (if so equipped) by loosening the
four screws holding it to the pump housing.
•
Disconnect the pump from the motor by removing the four screws holding them
together. Using three of these screws as jackscrews in the threaded holes provided on
the pump flange, pull the pump from the motor. Save the key from the motor shaft.
•
Mark the position of the cover in relation to the housing.
•
Remove the cover screws, cover and idler.
•
Remove the rotor by pressing on the hollow drive shaft with an arbor of approximately
1.375" (35 mm). With model CC009 pumps, the mechanical seal will remain in the
housing. With model CC015, CC020 and CC030 pumps, the rotating element of the seal
will come out with the rotor.
•
For model CC009, remove the retaining ring in the bore of the motor mounting and the
mechanical seal.
•
For models CC015, CC020 and CC030, remove the seal spring and rotating member
from the rotor and the seal seat from the housing.
