Changing Rotation - Models C1F and C1FA
Looking at the pump from the shaft end with the ports up, note the location of the V notch
in the bracket. If at the top (12 o'clock), rotation is clockwise; if at the bottom (6 o'clock),
counterclockwise.
•
Remove the cover screws so that the bracket moves freely.
•
Rotate the bracket 180°.
•
Align the mounting holes and reinstall the cover screws.
Model C1F, C1FA
If outfitted with an internal relief valve (models C1FV and C1FAV), 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
reversing feature (models RC1F and RC1FA), the following must be done in addition to
the above steps:
•
When rotating the bracket, also rotate the cover 180°.
Model C1B
Seal Replacement
•
Grip the pump firmly across the ports and opposite side of the housing in a vise
with the shaft end up.
•
Remove any burrs or nicks on the shaft. Use a small, fine file if needed.
•
Remove the bearing cap screws.
•
Slide the bearing cap off the shaft.
•
Remove the stationary seat of the seal from the bearing cap.
•
Slide the seal cartridge off the shaft.
•
Polish the pump shaft with crocus cloth or very fine sandpaper and clean the
seal
chamber thoroughly with a clean cloth. This will prevent damage to the new seal
and ease installation.
•
Place the new seal cartridge on the shaft and slide into place.
