50 Hours Cont'd
Lubricate the packer wheel hub. One lubrication fitting
•
is standard on each packer hub
100 Hours or Yearly
•
Remove all dirt and debris from the implement that
could hold moisture and cause rusting.
•
Repaint any chipped areas or clean and paint rusted
areas.
•
Inspect the machine for any work or damaged parts
and replace immediately.
Grease
Use Wil-Rich 460 ep lubricant as listed in all the appli-
cations. Wil-Rich 460 ep lubricant is not an all purpose
grease. Because of the heavy weight of the grease, it
should not be used at high-speeds or in small bearings.
4.2 Servicing the Wheel Bearings
Each wheel hub is equipped with a grease fitting and
must be lubricated every 50 hours of use. Apply grease
to the hubs until grease pushes out through the seal. The
triple lip seal lets the grease through without damaging
the seal.
Clean and fill the wheel hubs yearly. Cleaning and filling
the hubs removes all the dirt and supplies fresh grease.
The following procedure is necessary to correctly install
the triple lip seal. The seal lips must be showing away
from the hub if dirt is to be kept out.
Procedure.
1. Remove the dust cap, cotter pin, nut and washer
2. Remove the hub and clean the bearing and bearing
cavity.
3. Replace any damaged or worn parts.
4. Fill the hubs with grease.
5. Install the seal on the spindle shaft.
6. Replace the hubs with inner bearings in position.
7. Replace the outer bearing, washer and nut on the
wheel spindle.
8. Adjust the bearings by tightening the nut until their is
resistance to turning.
9. Loosen the nut until the hub can turn freely by hand
with out end play.
10. Put the cotter pin through the spindle and nut and
replace the dust cap.
11. Slide the seal (1) down the spindle turn the seal on
the spindle so the seal lips will point away from the
hub.
12. Install the seal in the hub.
4.3 Servicing the tandem pivot bearings.
Clean and fill pivot bearings yearly. Cleaning and filling
the bearings removes all dirt and supplies fresh grease.
The following procedure is necessary to correctly fill the
bearings.
Procedure:
1. Remove the wheels and tandem axle spindles.
2. Remove th seals and bearing from the pivot hub.
3. Clean the parts and hub cavity to remove the debris.
4. Fill the bearings in the hubs in the correct sequence.
5. Replace the bearings in the hub in the correct se-
quence.
6. Apply grease around the outside of the inner bear-
ing. Applying enough quantity to fill the space
between the inner bearings and grease seals after
assembly.
7. Install seals into the hubs. The metal side must be
on the outside of the hub.
8. Install the tandem axle spindle and replace the pivot.
9. Tighten the nuts until there is medium to heavy drag
to still rotate under the load. Loosen the nuts until
the cotter pin can be installed.
10. Replace the wheels.
4.4 Storage
The machine should be stored inside and unfolded if
possible, park the machine in a flat level area. Unfold
the wings to remove the load of the main frame carrying
wheels.
If the machine is parked on a soft surface place support
under the lift wheels to prevent sinking into the ground.
When storing the machine at any time if hitched to a
tractor or not, always relieve pressure to the wing fold
circuit. This can be accomplished by using the float
circuit of the tractor. Move the hydraulic lever tot the float
position to relieve pressure in the wing fold circuit before
unhitching the tractor.
