Bearing Assembly Tech Tips:

To grease, or not to grease?

A 2-row ball bearing is used in Yetter residue managers along with some coulter  and closing wheel assemblies.  This durable bearing comes sealed from the manufacturer.

To grease, or not to grease?  We get asked this question quite often from customers.  It is our experience that greased bearings last longer under normal field operating conditions, compared to sealed bearings. 
 

To grease the Yetter bearing assembly, pry off the inner seal with a small screw driver, or awl, and discard.

During the final assembly of the Yetter product, make sure that grease filling holes align in all components.  See owner's manual for more details.

The outer seal of bearing hub assembly has a reverse-lip that allows grease to escape and not let contaminates enter.  We recommend pumping grease in bearing assembly until clean grease exits between the outer seal and bearing insert.  This ensures that clean grease is inside the bearing assembly.  Also, grease is available for lubrication of the outer seal as it turns on bearing insert.  Lubrication helps prevent grooving of the bearing insert which can lead to the entry of contaminates.
