Lubrication Maintenance
The 7812 HSL features a maintenance free double
tapered roller bearing in each disc hub (Landoll P/N
185742). The maintenance free double tapered bearing is
protected by a life time lubricated five lip seal (Landoll P/N
185757) on the hub’s spindle side.
See Figure 4-1. 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 disc. Should it become necessary
for a disc hub bearing to be replaced there are two options
available.
1. A complete hub assembly (Landoll P/N 210880),
ready to install.
2. A rebuild kit (Landoll P/N 219945) with all required
components.
• The rebuild kit comes with instructions (P/N
219946)
• Installation of the HSL hub rebuild kit requires a
die (P/N 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 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. The Lubrication Table below specifies the number
and the period of lubrication points on the 7812 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.
