Supplementary Instructions for Servicing the CC-60B
Flex-I-Liner Pump
Except for a greater overall length, this pump is essentially the same
as the following models CC-2B, CC-6B, CC-12B, CC-18B and CC-30B.
(Refer to Figure A-3). Important differences include:
(1) The first outboard bearing (13) on the abovementioned drawing
is of extra heavy-duty double roll construction. Although
counterpart bearings used on the other pumps are
interchangeable with this bearing, they should not be
substituted for the specified bearing due to the heavier loads
encountered during operation.
(2) The bearing spacer (32) is somewhat narrower due to the
greater width of the first outboard ball bearing.
(3) The interior of the rotor (5) contains one extra part (item 16) —
the bearing guard spacer.
(4) The rotor bearing (14) is of heavy-duty roll construction and not
interchangeable with the ball bearing used in the remainder of
the series.
(5) The size CC-60B pump employs a 1 /
2
HP motor, the remainder
of pumps in this series employs 1 /
4
HP motors.
Even though the pump contains additional and somewhat different
parts, the method of disassembly and assembly is identical to the instruc-
tions for the CC-2B through CC-30B series and should be closely fol-
lowed.
