MAINTENANCE
LUBRICATION: USE #2 MULTI-PURPOSE LITHIUM GREASE
To ensure longevity and reliability of the Maverick Opener , the recommended lubrication schedule
should be followed using multi-purpose grease at hourly intervals as indicated.
BEARING ADJUSTMENT:
1. Raise the toolbar until the blade is clear of the ground. Place a safety stand under the toolbar.
Remove the cotter pin, slotted nut, washer and bolt from the hub assembly. Remove the blade
from the hub assembly.
2. Remove bearing cones and seal from the hub.
3. Wash the old grease from the hub, bearing cups, spindle spacers, seals and bearing cones.
Inspect the condition of bearing cups, cones and seals. Replace if necessary.
4. Apply #2 multi-purpose lithium grease on each bearing. Make sure the space around each roller is
filled. Lubricate the bearing cups.
5. Position the bearing in the cup and install the seal. Lubricate the seal lips and proceed with re-
assembly of the removed parts including the blade. Blade bolt torque is 90 to 96 ft/lbs.
6. Tighten the slotted nut to 10 to 15 ft/lbs. or until a definite drag is felt when the blade is turned by
hand. Back off the nut one slot position to line up the cotter pin hole with a slot. Secure the nut
with a new cotter pin.
KNIFE WEAR:
The lower portion of the knife and tube are subject to wear during operation. The rate of wear will
depend on a variety of factors and in abrasive soil conditions the wear will be more rapid.
NOTE: In certain areas, replacement knives should be kept in stock, replacing worn knives as needed.
