4-11 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:
4-11.1 Place the frame on blocks or stands
sufficient to lift the tire clear of the ground.
4-11.2 Remove the hub cap, cotter pin, slotted
nut and washer.
4-11.3 Remove the hub. Clean and inspect the
bearings and hub cavity. Replace any worn
or defective parts.
4-11.4 Repack the bearings using a high-
quality wheel bearing grease.
4-11.5 Replace the hub with a new seal and
the inner bearing in place.
4-11.6 Install the outer bearing cone, washer
and slotted nut.
4-11.7 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.
4-11.8 Install a new cotter pin and replace the
hub cap.
4-12 HYDRAULIC MAINTENANCE
4-12.1 Check the tractor hydraulic fluid level
per tractor owners manual and after any
leakage. Check fluid level with the cylinders
in the retracted position.
4-12.2 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.
4-12.3 Check all hydraulic hoses weekly. Look
for binding or cracking. Replace all worn or
defective parts immediately.
4-13 LUBRICATION
4-13.1 Table 4-1 and Figure 4-5 specifies the
number and the period of lubrication points
on the 876 Wing Series Tilloll . Proper main-
tenance of your machine will, under normal
operating conditions, help to keep it operat-
ing at or near its peak performance for an
extended period of time. Proper maintenance
is also a condition of keeping your warranty
in good status.
