Wheel Bearing Maintenance; Coulter Spring Adjustment; Lubrication - Landoll 1550 Series Operator's Manual

4-5 WHEEL BEARING MAINTENANCE

4-5.1 Check wheel bearings and coulter bearings
occasionally for excessive end play. To cor-
rectly replace the wheel bearings:
4-5.2 Place the frame on blocks or stands suffi-
cient to lift the tire clear of the ground.
4-5.3 Remove the hub cap, cotter pin, slotted
nut, and washer.
4-5.4 Remove the hub. Clean and inspect the
bearings and hub cavity. Replace any worn
or defective parts.
4-5.5 Repack the bearings using a high-quality
wheel bearing grease.

4-6 COULTER SPRING ADJUSTMENT

4-6.1 No spring adjustment is necessary on the
coulters. All adjustments were made before
shipping at the factory. Initial operating force
to move coulter upwards is 540 pounds. The
preload has proved to be more than ade-
quate for most conditions.
