19� Shift the housing so that
the intake (Square port) is
hanging slightly off of the
rebuild work surface�
Place one of the 0�007” shims
between the rotor and rotor
bore so that the shim is within
the housing and will not
interfere with the endplate when
they are reinstalled�
Divert the pull wire into the
housing cavity and out through
the intake port�
Repeat for both ends of the
rotor�
18� Inspect the original vanes for
any delamination, chipping
or other damage�
A new vane is flush with the
outside diameter of the rotor�
If any of the vanes are worn
more than 1/4”, chipped or
delaminated they should be
replaced�
We highly recommend
replacing vanes in sets� Apply
a liberal amount of lubricant to
the vanes before installing in the
rotor slots�
It is always a good idea to have
a spare set of replacement
vanes on hand to reduce
pump downtime�
