Bearing Replacement in Nose Assembly
The metershaft assembly is fitted with
a special bearing at the drive end of the
shaft in the nose assembly. This bearing
requires regular greasing, as do the other
metershaft
bearings,
and
should
be
inspected for serviceability at the beginning,
end and at least once during the middle of
the planting season.
To inspect the bearing simply remove
the metershaft assembly housing from the
meterbox as previously described and rotate
the shaft by hand. If there is a resistance in
turning, or the bearing does not turn with the
shaft, remove the nose assembly for closer
examination.
To remove the Nose assembly:
1. Remove the drive pin from the end of the
metershaft by undoing the grubscrew
and pushing the pin out through the slot
in the plastic housing.
Fig. M29 Undoing the grubscrew from the
metershaft assembly.
2. Remove the 3 button head screws that
retain the nose assembly to the
metershaft housing and remove the nose
assembly from the shaft.
3. Hold the assembly in one hand and
rotate the bearing.
4. If the bearing feels rough as it rotates
replace the bearing by removing the 3
phillips head screws from the steel plate
and pushing the bearing out
Fig. M30 Checking the bearing.
5. Replace bearing if necessary and refit
bearing and nose assembly. Grease the
bearing and check that grease is
expelled from the bearing. Two pumps of
the grease gun should be sufficient.
Do
not over grease the nose bearing
.
