Relieve all internal pressure before servicing.
Serious injury or death from fire or explosion could result from maintenance of an
Meter Disassembly: (refer to diagram on page 16).

If your meter is equipped with an electronic register,
remove the register and register housing assembly.

Disconnect the outlet flange (44) and the vapor tube
connecting the differential valve and the vapor return
line.

Remove the four bolts (24) and the dust cover (23).

Disconnect the outlet wiring from the electronic pulser
assembly (SCL) terminal TB1 (See SCL service manu-
al)
Note: If the SCL does not require service, and there is
no damage to the meter cover (4), it is possible to re-
place the meter using the existing meter cover. In this
case it is not necessary to disconnect the outlet wiring.

Remove the 12 bolts (9) and the SCL housing (4).

Inspect the internal parts for wear. Gears may be re-
placed at this point if all other components are good.

Remove the bolts (28) and remove the differential valve.

Remove the 12 bolts (9) and the meter assembly (body
(1) and post plate (3).

Clean all surfaces using a brush or fine (200 grit) emery
cloth.

Inspect and repair the inlet check valve if you have this
option.

Inspect the meter body for damage. Use 200 grit paper
to remove small scratches and blemishes. If the dam-
age is more than superficial, replace the body.

Inspect the post and post plate. Replace if there is any
wear.

Inspect the O-ring seals, and replace any damaged or
brittle seals.
Flow Meter Maintenance
Line pressure must be 0.0 PSI
improperly de-pressurized and evacuated system.
Danger!!

Reinstall the meter in reverse order.

Install a new oval gear set (11) if necessary. Gears
should be perpendicular to each other. The gears will
not rotate a complete revolution if not installed properly.
Once installed, the gears should rotate freely with out
binds or rubs. Check the clearance between the gears
and the body. There should be a minimum of .003 inch
between gears (11) and the meter cover (4). If there is
any binds or rubs between the gears and the meter
body, it is recommended that the meter be replaced.

Reinstall the meter cover (4).

Reinstall the differential valve.

It is recommended that all O-rings and seals be re-
placed during service, but a good inspection is critical if
seals are reused.

Calibrate the meter and return to service.
