OPERATION AND MAINTENANCE
Lubrication Maintenance
1. Table 4-1 specifies the number and the period of
lubrication points on the 6250 Disc. Proper
maintenance of your machine will, under normal
operating conditions, help to keep it operating at or
near its peak performance for an extended period of
time. Proper maintenance is also a condition of
keeping your warranty in good status (See
Figure 4-25.)
2. When lubricating the Disc, SAE multi-purpose EP
grease, or EP grease with 3-5% molybdenum sulfide
is recommended. Wipe soil from fittings before
greasing. Replace any lost or broken fittings
immediately.
4-24
3. Disc gang and conditioner reel bearings are
equipped with seals that will let grease pass and not
harm the seal. Regular lubrication will maintain a full
grease cavity and help purge any contaminants.
Grease the bearings before long periods of storage
to prevent moisture buildup within the bearing cavity.
4. Center frame hub seals will allow grease to pass
without harm to seals. For wheel bearing
maintenance, refer to "Center Frame" on
page 4-19.
5. Wing wheel hub seals when properly installed will
allow grease to pass without harm to seals. For
wheel bearing maintenance, refer to "Wing Frame"
on page 4-20.
6. Grease all walking tandems until grease is purged
out both sides of pivot. Walking tandems must be
greased daily.
7. Regular lubrication will extend service life,
particularly in severe operating conditions.
8. The Disc is equipped with maintenance-free
bearings in the lifts, leveler, wing hinges and gauge
wheel casters. These areas require no lubrication.
