Rotor Replacement.
There is only one moving part to this
meter. The bearings are made of ruby, which rarely wears
out or needs replacement unless they have been physically
damaged by severe shock. The shaft is integrally molded into
the rotor, and shaft and rotor are replaced as one part. (You
may wish to replace the bearings, using the bearing removal
tool, while the meter is disassembled for rotor replacement).
To replace the rotor, disconnect the meter and remove the
four screws that hold the cover in place. Lift the cover and
remove the rotor (see parts diagram below).
When putting in the new rotor, be sure that the ends of the
shaft are in both bearings before tightening the cover. The rotor
can be easily dropped into the bottom bearing. Starting the
shaft into the upper bearing requires a bit of care. It is easier
if the rotor is spinning, which can be done by lightly blowing
into a port. When the upper bearing plate drops into place,
hold it down and check for free spinning (by blowing lightly)
before replacing the cover. Check that the O-ring is in its seat
on the bearing plate before replacing the cover. Replace the
cover, insert the four cap screws and tighten.
