(7) Install new Flex-I-Liner: clean all chemicals from exposed parts
of pump.
(8) Apply a liberal amount of Vanton Pump oil to the inside of the
Flex-I-Liner. Spread this oil over the inside interior to the very
edge.
(9) Push the body block back onto the bracket. Shaft should be
rotated at the same time that pressure is being applied to the
block to push it “home”. This will allow the Flex-I-Liner to seat
over the Pilot of the bracket. It is suggested that the shaft be left
in top dead center position once the block has been forced
“home”. If the Flex-I-Liner is properly seated, the block will
remain close to the bracket when hands are removed from the
block; if improperly seated, the block will spring back from the
bracket. Failure to have Flex-I-Liner properly seated prior to
taking the next step will result in Flex-I-Liner crimping and
improper pump performance.
(10) “Snap” expansion ring into Flex-I-Liner.
(11) Replace cover plate.
(12) Replace the four bolts and tighten each a little at a time, like
one tightens a tire rim. Rotate shaft a number of times before
bolts are drawn tight.
The pump is now ready for operation. Usually, the foregoing is all
that will ever be required in maintenance because of built-in protection
features of the CC-B Series Pump. Should the bracket assembly, after long
service, require repair, the following procedure should be followed:
(13) Remove body block, casing cover plate, four bolts and support
bracket as described in steps (1) through (12).
(14) The entire assembly remaining on the motor should then be
detached from the motor by removing four socket-head cap
screws (12) along with their shakeproof washers (11) and
finally loosening the coupling set screw (10). Tap subassembly
gently to remove.
