MAINTENANCE
LUBRICATION: USE #2 MULTI-PURPOSE BEARING GREASE
To ensure longevity and reliability of the U.N.T. Coulter, 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 hubcap, cotter pin, slotted nut and washer from the hub assembly. Remove the blade
from the hub assembly.
2. Remove bearing cones and seals from hub.
3. Wash the old grease from the hub, bearing cups, spindle spacers, seals and bearing cones.
Inspect the condition of the 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 15 ft. lbs. or until a definite drag is felt when the blade is turned by hand.
Tighten the nut one slot position to line up the cotter pin hole with a slot. Secure the nut with a new
cotter pin, replace hubcap.
