Installation/Operation/Parts
Replacing Bearing and Seal Assembly (Item 48, New Style)
To replace the bearing and shaft seal assembly (48), or service the gear train on back of register
housing (18), remove housing from meter by taking out four screws.
NOTE: The meter housing
will be full of liquid so some means should be available to catch what drains from the case and
lines. To remove gears (22-25), remove three retaining rings (20) and drive key (21). Withdraw
the drive shaft and gear (14), spacer (15), and all parts of bearing and seal assembly (48).
Remove the nylon washer from item 48 and note its location. Remove both oilite bearings and
both O-rings from bore in register housing. Using new parts, which consist of a new nylon washer,
2 oilite bearings, and 2 O-rings, reassembly parts in reverse order. Be sure to lubricate both O-
rings with an O-ring lubricant before assembling.
Reassemble Gear Train
Reassemble gear train as follows: gear (24), key (21), cluster gear (25), retaining ring (20), control
block (22), and retaining ring (20).
B-SIZE MEASURING CHAMBER DISASSEMBLY
The B-size measuring chamber can be removed for cleaning by taking out the four meter body
screws (33) and lifting off the register housing (18). Remove the three measuring chamber screws
(26). After separating the two halves and cleaning, reassemble, making sure the metal baffle (30)
is seated in the groove in the two halves and through the slot in the measuring disk (29). Do not
sharply strike or drop the phenolic parts while handling. Rotate the disk (29) to make sure it turns
freely and replace in the meter body (32). Do not overtighten the screws. A torque of 20-25
pounds is sufficient. When reassembling the register to the old meter body, use a new O-ring
(19).
