Maintenance
Wheel bearing maintenance should be performed at the
beginning of every season of use. Check the wheel
bearings periodically for excessive end play. If needed,
adjust or replace them using the following procedure:
1. Place the Frame on blocks or stands sufficient to lift
the Tire clear of the ground.
2. Remove the Tire.
3. Remove the Hub Cap, Cotter Pin, Slotted Nut and
Washer.
4. Remove the Hub. Clean and inspect the Bearings and
Hub Cavity. Replace any worn or defective parts.
5. Repack the Bearings using a high-quality Wheel
Bearing Grease.
6. Install the inner bearing into the hub and install the
grease seal. Use a driver to install the seal, to avoid
damaging the outer edge of the seal. Drive the seal
squarely into the hub to avoid any seal distortion.
NOTE
The Triple-Lip Seal should point away from the Hub to
keep contaminants out and allow grease to pass.
7. Slide the hub, bearing, and seal onto a clean spindle
8. Install the Outer Bearing Cone, Washer and Slotted Nut.
9. 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 the end play.
10. Install a new Cotter Pin and replace the Hub Cap.

Lubrication Maintenance
The 4620-24 Folding Seeder is equipped with
maintenance free bearings in the lifts and wing
assemblies. These areas require no lubrication.
Roller assembly bearings are sealed with a triple lip seal
and are non-lubricable.
•
Grease Wheel Hubs every 50 Hours. See
Figure 5-2.
•
When the machine is not used for some time,
exposed portions of the hydraulic cylinder rods must
be cleaned and covered with a thick coat of grease to
prevent corrosion, which will damage the seal.
