. The centrifugal unloader weight
retainer assembly [

,

,

and
J
] may be assem-
bled to the crankshaft in either of two methods:
The preferred method is to mount the assembly to
the crankshaft when crankshaft is removed from
base during assembly of pump.
The second method is used when only the centrifugal
unloader is to be dismantled, and only the end cover
[
L
] is removed. Then centrifugal unloader weight
retainer assembly [
E
,
F
,
G
,
H
and
J
] may be assem-
bled when crankshaft is in base.
