4-5 WHEEL BEARING MAINTENANCE

Wheel bearing maintenance should be per-
formed at the beginning of every season of use.
Check the wheel bearings periodically for exces-
sive end play. If needed, adjust or replace them
using the following procedure:
4-5.1 Place the frame on blocks or stands suf-
ficient to lift the tire clear of the ground.
4-5.2 Remove the hub cap, cotter pin, slotted
nut and washer.
4-5.3 Remove the hub. Clean and inspect the
bearings and hub cavity. Replace any worn
or defective parts.

4-6 LUBRICATION

Several parts of the Model 2320 Series Weath-
erproofer II need periodic lubrication. Use of a high
grade multi-purpose grease is recommended. Refer
to the Weatherproofer Lubrication Chart (See Fig-
ure 4-4) to locate lubrication points and for a rec-
ommended maintenance schedule.

4-7 HYDRAULIC MAINTENANCE

4-7.1 Check the tractor hydraulic fluid level
per tractor owners manual and after any
leakage. Check fluid level with the cylinders
in the retracted position.

4-5.4 Repack the bearings using a high-
quality wheel bearing grease.
4-5.5 Replace the hub with a new seal and
the inner bearing in place.
4-5.6 Install the outer bearing cone, washer
and slotted nut.
4-5.7 Tighten the slotted nut while rotating the
hub until there is a slight resistance to wheel
rotation. Then, back the slotted nut off one
notch, until the wheel rotates freely without
end play.
4-5.8 Install a new cotter pin and replace the
hub cap.
4-7.2 If a cylinder or valve leaks, disassemble
the parts to determine the cause of the leak.
Any time a cylinder is opened up, or when-
ever any seal replacement is necessary, it is
advisable to clean all parts and replace all
seals. Seal kits are available from your Lan-
doll dealer.
4-7.3 Check all hydraulic hoses weekly. Look
for binding or cracking. Replace all worn or
defective parts immediately.
d. Grease all exposed metal surfaces of
shanks, points and discs.
e. Lubricate each point of the machine as
stated in Section 4-6.
4-8.2 Store the unit in a shed or under a tar-
paulin to protect it from the weather. The
ground tools and tires should rest on boards,
or some other object, to keep them out of
the soil.
