TINE BAR BEARINGS
Tine bars are removed from the spider legs as
detailed in the "Tine Bars" portion of this section.
1. Carefully remove the dust cap from the bearing
housing. Remove the snap ring. Remove the
bearing from the bearing housing by placing the
nut on the threaded end of the bearing stud and
tapping against the nut. In some cases it may be
necessary to place spacers against the shoulder
of the bearing housing and pull the bearing out of
the housing by tightening the nut against the
spacer.
2. Clean all parts thoroughly. Dirt or grit will cause
excessive bearing wear.
3. Pack the tine bearing level full of multipurpose
grease or a good grade of wheel bearing grease.
4. Tap the bearing into position. Be sure it is seated
against the shoulder of the housing. Install the
snap ring.
5. Fill the cavity on the outer side of the bearing
slightly more than level full of wheel bearing
grease or a good grade of heavy water pump
grease.
When the dust cap is installed, the grease should
fill the area under the cap to provide a seal
against dust or dirt. However, too much grease
will force the dust cap out of position. The dust
cap should fit snugly on the shoulder of the
bearing and be 0 mm -1 mm (0"-1/32") past the
shoulder of the bearing.
6. Replace the tine bars. Be sure to use special
washers on each side of the spider as detailed in
the "Tine Bars" portion of this section.
WARNING
Disengage the PTO, turn off the tractor engine
and remove the key. Wait for all movement to
stop before leaving the operator's position.
Never adjust, lubricate, clean or unplug machine
with the engine running. Failure to comply could
result in death or serious injury.
