Fill-Rite TS SS F & W Precision Meter - Manual (Page 18)

4. Remove 4 screws (20) from bearing plate assembly (4),
and pull the bearing plate off the meter body. If the bear-
ing plate is stuck to meter body, gently tap with a rubber
mallet, or use a 5/16-8 x 1” jack bolt to push it free.
5. Inspect inside of bearing plate (4) for scoring (minor
markings is acceptable). If the bearing plate is scored, it
should be replaced
6. Verify that the drive shaft (29A) for the magnet assembly
is turning smoothly.
6.1 If it wobbles, replace bearings (2 x 29B).
6.2 If the drive shaft is worn,
replace magnet drive assembly (29A, B & C).
7. Before removing oval gears, mark across both gears (2)
with a soft pencil for alignment during re-assembly.
7.1 Extract the gears, and inspect for wear or damage.
Replace
if necessary.
7.2 Inspect the interior of the measuring chamber and
the post plate assembly for wear or damage. Re-
move any deposits using a fine emery cloth, or fine
wire brush; be careful not to score or damage any of
the internal parts.
7.3 If posts, or post plate, are worn, the complete
assembly must be replaced. To replace, see D.
 Reassemble in reverse order:
 Align oval gears on mark made prior to disassembly.
 Installing new gears, the lower gear must be at 90° to
the upper gear, when the upper gear is horizontal.
Make sure that the gears turn freely on the shafts, and
do not rub or bind against the housing (1). Nor should
there be excessive clearance. Leave the top gear with
the slot for the coupling (29A) in horizontal position
.
 Re-attach the bearing plate (4) with coupling/magnet
(29) in the up position. Align with dowel pins, and

Flow Meter - Disassembly
A. Pulser O-ring (16), or Pulser (10)
First relieve system pressure and drain the flow meter.
1. Remove 4 screws (12a) from the dust cover (12), and
detach the dust cover.
2. Release signal cable from TB1 on the board (13).
3. Release pulser (10) leads from
J1 on terminal block
board/SCL (13).
4. Remove 2 terminal block board/SCL screws (13a), and
take the board (13) out. Place on a clean & dry surface.
5. Remove 3 retainer screws (11a), and detach the retainer
(11). The pulser (10) can now be removed, so the O-ring
(16) can be replaced.
 Reassemble in reverse order, checking all O-ring seals
for damage. Teflon O-rings must be replaced whenever
the flow meter has been opened.
B. Bearing Plate (4)
C. Oval Gears (2)
First relieve system pressure and drain the flow meter.
In a W●● flow sensor with remote register, items 7, 8, 9, 18
& 26 are not included. Here the front cover can be removed
directly for access to flow meter internals after signal cable
has been disconnected. In an F●● flow meter with register,
remove the two screws (18) from the clamp (8) and take the
clamp off - leaving the register in place on the flow meter.
1. Remove 4 screws (12a) from the dust cover (12), and
detach the dust cover.
2. Release signal cable from TB1 on the board (13).
3. Remove cover screws (19) from the front cover, and slide
the cover off the flow meter (downwards), leaving the
register in place on the flow meter. Be careful that the
plug on the output cable slips up through the stand-off (9);
if the plug catches on the edge, it might pull off.
When servicing meters with Teflon
seals, replace all seals every time
the flow meter is serviced.
