Milk Meter Dis-Assembly
The Milk Meter can be disassembled almost totally by hand, although the more complicated components
require the use of the tools shown on page 1. Loosening and fastening the connections should be done with
care.
Note positions/orientation of plunger, outlet and top bracket.
As the meter is dismantled, place each part removed in a safe and clean container to ensure no part is lost
or damaged.
Place the meter into the Milk Meter Stand.
Loosen and remove the three top M6 flanged nuts and three compression springs.
Remove the Top Bracket.
Pull the top of the meter upwards to remove the top and plunger assembly (complete) from the main
meter body.
With the top/plunger assembly on the desk, gently prise the vacuum nipple out of the meter top breaking
the seal made by the ‘o’ ring.
Gently pull the vacuum nipple away from the meter top taking care not to over-stretch the spring and
slide the spring retaining blade between the coils of the spring.
With the spring tension now removed from the vacuum nipple use the spring retrieval hook to push out
the cross pin; remove the spring retaining blade.
The vacuum nipple and cross pin are now free. Remove the ‘o’ ring from the vacuum nipple.
Gently pull the plunger down from the meter top piece to break the seal around the outside edge of the
meter diaphragm.
Unhook the spring from the top of the plunger assembly using the spring retrieval tool if necessary.
Loosen and then unscrew nyloc nut and clamping disk – The diaphragm can then be removed.
Remove the plunger seal from the bottom of the plunger.
Remove the main meter body from the meter base by guiding it upwards between the tie rods.
The meter bottom seal can now be removed.
The probes and probe grommets are removed from the body by pulling the probes from the grommets
and then pulling the grommets from the meter body.
The meter is now completely dismantled.
IMPORTANT
The relevant service parts should be examined and then exchanged for new ones before the meter is
reassembled.
