Assembly
Note:
When assembling the meter, use a light coating of Loctite 242
on all threaded items. For pipe plugs, use Loctite 567.
Once all of the clearances have been taken, determine
which parts require replacement.
Use Emory Cloth or a file to remove any burs that may
have developed from disassembly and cleaning.
Take caution while assembling and do not force any
steps. If something needs to be forced, then there may
be a problem.
After the meter is reassembled, the clearances will need
to be recorded one more time.
Install both Blades and Cam Shaft into the Rotor (Figure 33).
Keep in mind that if the same Blades are to be reused,
then they will need to be installed in the same position
they were removed from.
The Rotor Cover will only fit in one orientation. Note the
two pins and corresponding holes (Figure 34).
Install the Rotor Cover and Blade Retainer. Prior to
installing the twelve Retainer Bolts, apply a light coating
of Loctite 242 to the threads and torque the bolts to the
appropriate specifications (Figure 35):
2" Torque Values: 50 in/lb (6 N
•
m)
3" Torque Values: 150 in/lb (17 N
•
m)
Once the Rotor and Blades are assembled, hold the
bottom of the shaft and spin the assembly to check for
binding. The assembly should spin freely.
The Rotor and Blade Assembly is ready to be installed
into the Housing. If there were no parts replaced, you
can install the same Shims that were removed when the
meter was disassembled. If there were parts replaced,
then Shims may be added or removed accordingly
(Figure 36). The Shims that are required can be found
using the Rotor to Shelf Clearance. Shims are only
installed on the bottom of the Rotor.

Install the Spring Washer over the Magnetic Coupling
to sit flat on the Rotor Cover. A light coating of grease
or petroleum jelly will help hold it in place.
