Assembly is a reversal of this operation.
Before
rebuilding
the
metershaft
assembly check that the bearings turn
freely. The bearing in the nose assembly will
be firm to turn but should rotate and feel
smooth in its operation. If excessive force is
required, or a bearing feels rough when
rotating replace bearing before re-assembly.
Clean hexagonal metershaft of product build
up to allow the meterwheels free movement
along the shaft.
Check that the meterwheels are in good
condition & not worn before re-assembling.
Check that the vertical spacers attached to
the housing are not excessively worn and
are still functional. The vertical spacers are
used to retain the meterwheels in position.
Replace individual units if required.

Check that the drive pin on the end of the
