Lubrication Maintenance - Landoll 7831 Operator's Manual

Lubrication Maintenance

1. The 7831 HSL features a maintenance free double
tapered roller bearing in each disc hub (Landoll Part
No. 174526). The maintenance free double tapered
bearing is protected by a life time lubricated five lip
seal (Landoll Part No. 185757) on the hub's spindle
side (See Figure 4-7.) The joint between the disc
blade and the hub face is sealed with silicon during
assembly at the factory. Should it become necessary
for a disc hub bearing to be replaced there are two
avenues available. Landoll Parts Department offers a
complete bearing assembly ready to install (Landoll
Part No. 185742). They also offer the component
parts required (please reference the parts manual.)
2. When lubricating the HSL, 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.
OPERATION AND MAINTENANCE
3. Disc gang and 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. Table 4-2 specifies the number and the period of
lubrication points on the 7831 HSL. Proper
maintenance of your machine will, under normal
operating conditions, help to keep it operating at its
peak performance for an extended period of time.
Proper maintenance is also a condition of keeping
your warranty in good status (See Figure 4-8.)
