Lubrication Maintenance - Landoll VT Plus 7550 Operator's Manual

OPERATION AND MAINTENANCE

Lubrication Maintenance

1. A proper maintenance schedule will insure a long
operating life and peak performance. Performing the
following lubrication will ensure maximum operating
life of the 7550 (See Figure 4-22.
Figure 4-23.).
2. When lubricating the 7550, 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.
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. Both center frame and wing wheel seals, when
properly installed, will allow grease to pass without
harm to seals. Regular lubrication will extend service
life, particularly in severe operating conditions.
5. Grease walking tandems every 50 hours or as
needed to purge contaminated grease will purge with
no harm to walking bearing.
6. The 7550 is equipped with maintenance-free
bearings in the lifts, leveler, wing hinges. These
areas require no lubrication.
