After a few days use, check coulter hubs for loose bearings. There should be no end play in the hub
bearings to allow it to wobble. If necessary, remove hub cap and cotter pin, adjust slotted nut to remove
wobble, re-insert cotter pin and replace hub cap.

1.
Raise the toolbar until is clear off the ground. Remove the gauge wheel and the blade. Remove the hubcap,
cotter pin, slotted nut and washer from the spindle shaft assembly.
2.
Pull the coulter spindle shaft assembly from the hub. Remove bearing cones and cups and discard if bearings
are being replaced. Clean hub and dry. Remove bearings only and not cups of re-packing.
3.
Wash the old grease from the hub, bearing cups, coulter spindle shaft, seal, and bearing cones. Inspect the
condition of bearing cups and cones.
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.
Install outer bearing, washer, and slotted nut. Tighten the slotted nut to 150 in. lbs. while rotating the blade 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.
