Removing Metershaft Assembly
1.
Ensure that the bin is empty before
attempting to remove the metershaft
assembly.
2.
Undo the 2 captive nuts on the left
hand side of the meterbox using the
Tee wrench supplied.
3.
Use the tapered end of the Tee
wrench’s handle to release the
metershaft assembly seal against the
side of the meterbox.
Fig. M13 Tee wrench releasing seal pressure.
4.
Grip the handle and pull the metershaft
assembly outwards. The assembly
should slide out freely. If the assembly
jams or is hard to remove check that
the diverter blades are not restricting
movement and release the trapdoor
handle to reduce pressure under the
metershaft assembly.
Fig. M14 Removing the metershaft assembly.
Assembly is a reversal of this procedure.
Note: When refitting the metershaft
assembly check that:
The metershaft nose bearing has been
greased
(refer page 113).
The drive pin has engaged correctly.
The diverter blades are still in the
same position as required.
Fig. M15 Ensure Drive pins & metershaft pin
miss each other when engaging.
Removing Meterwheels
1.
Remove metershaft assembly from
meterbox as previously described.
2.
Clean
metershaft
assembly.
If
necessary use a high-pressure wash
with detergent.
Note: Take care not to spray water directly at the
bearings and shaft seal.
3.
Undo the 2 grub screws in the collar of
pillow block bearing (handle end) that
retain
the
metershaft.
Note
the
distance that the end of the shaft is in
the bearing. In most cases the shaft
will be flush with the end of the bearing
collar.
