OPERATION AND MAINTENANCE
Figure 4-8: Disc Hub Bearing
Lubrication Maintenance
1.
The 7833 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
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
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.)
•
Complete hub assembly (Landoll PN 185742),
ready to install.
•
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.
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.
3.
The wing gauge wheel hubs and the 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.
The table below specifies the number and the period
of lubrication points on the 7833 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 to keep your
warranty in good status.
