10.1.2 Assembly
①
Clean thoroughly the rotors, measuring chamber,
top and bottom covers, and other components in
suitable solvent. Exercise care to keep dust and
grime out before assembly.
②
Thrust rings (207) must be installed in their
original positions of respective rotors (201 and
202). Hold the thrust rings so that they will not
come off their rotors when tightening up thrust
ring setscrews (217). Ensure at this time that pins
for the thrust rings fit exactly in their slots on the
rotor side.
③
When installing the rotors, the 1st rotor is
identified as the one provided with signal magnet
(370) according to the flow direction specified.
The flow direction is from left to right in the
sketch shown above.
④
Match marks are stamped on the rotors as
shown in the inset of the sketch. Install the rotors
with these match marks aligned. When they are
in engagement, allow them to make several
revolutions to ensure their freely rotation.

10.1.3 Reconditioning the Rotor Gear Teeth
The hatched areas of one rotor shown in the sketch
at right indicate the areas in contact with the other
rotor while they revolve. Do not attempt to
recondition these areas unless it is absolutely
necessary to do so due to undue wear found during
disassembly and inspection.
If the rotors have score marks or deep scratches,
indicative of having jammed with foreign solids
between them, correct with an oil stone or similar
abrasive tool only the protrusions so made until the
affected areas are flush with other areas in height.
Other areas indicative of jamming with foreign
solids, if any, may be reconditioned according to
established shop practice.
