Inspect the PEEK
™
Blade Wear Strips (there are four
per Blade). The Wear Strips should be secure to the
Blade, not loose. They should also be slightly raised to
the Blade surface. If worn, the complete Blade should
be replaced.
Ensure that the cover Bearing spins freely. If not, it must
be replaced. It is recommended to use a spray solvent
to clean the Bearing.
The Block and Measuring Insert are removable. Inspect
for wear and replace, if needed.
Note:
Most repairs of the meter will not require the Block to be
removed. If the Block or Measuring Chamber Insert are removed,
ensure they are reinstalled in the same orientation. It’s strongly ad
-
vised to set the Measuring Insert Shims aside with the Measuring
Insert and set the Block Shims aside with the Block.
If the Block must be moved, the 1/2" NPT plug will need
to be removed to access the Button Head Screws that
secure the Block in place (Figure 30 and Figure 31).
When reinstalling, the Cinch Bolts should have Loctite
242 lightly applied. The NPT Pipe Plugs should have
Loctite 567 lightly applied as well.
