Reassembling the Meter
6. Slide the blocking rotor gear on its tapered rotor end.
Slide the right displacement rotor gear on its tapered
rotor end so that the timing marks line up between
the two gears.
HINT: Before placing the right displacement rotor gear
on its end, hold the right rotor gear in position. Turn
the blocking rotor gear. Line up the timing marks
before placing the right displacement rotor gear on
its tapered end.
7. Slide the left displacement rotor gear on its tapered
rotor end so that its timing mark lines up with the
blocking rotor gear.
8. Insert the rotor gear screw and flat washer into each
of the rotor gears and finger tighten.
9. Position the spare displacement rotor gear between
the left displacement rotor and the blocking rotor gear
to prevent the gears from moving. If a replacement
gear is not available, use a shop rag between the
teeth of the gears. Tighten the screws of the
displacement rotor gears to the torque specification
listed in the Torque Chart.
10. Position the spare displacement rotor gear between
the right displacement rotor and the blocking rotor
gear to prevent the gears from moving. Tighten the
screw of the blocking rotor gear to the torque
specification listed in the Torque Chart.
11. Rotate the gears to make sure that the rotors turn
freely. Burrs, foreign material, or marred surfaces
can restrict the rotor movements. It may be
necessary to remove the gears and rotors and deburr
or clean the surfaces again.
