TABLE OF CONTENTS
Lubrication Maintenance
The 7822 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 4-8 .) The joint between the disc blade and the
hub face is sealed with an O-ring that is compressed in a
groove in the hub and seals against the disk. Should it
become necessary for a disc hub bearing to be replaced
there are two options available.
1. A complete hub assembly (Landoll PN 210880),
ready to install.
2. A rebuild kit (Landoll PN 219945) with all required
components.
• The rebuild kit comes with instructions (PN
219946)
• Installation of the HSL hub rebuild kit requires a
die (PN 218733) to set the bearing and seals.
3. 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.
4. The wing gauge wheel hubs and the reel bearings
are equipped with seals that will let grease purge
without harming 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.
5. Table specifies the number and the period of
lubrication points on the 7822 HSL. Proper
maintenance of your machine will, under normal
operating conditions, help to keep it operating at its
peak performance. Proper maintenance is also a
condition to keep your warranty in good status.
