J. Lubrication – Bearings, Casters and Jacks
The flange bearings, pillow block bearings and casters supplied for use on Series II Sweeps are
shipped from the factory lubricated. From time to time a small amount of the proper lubricant must be
added. Over lubrication may cause premature failure of the components.
K. Procedure for Lubricating Flange and Pillow Block Bearings
1. Disconnect and lock motors out of service.
2. Follow all safe bin entry procedures and wear all required personal protective equipment.
3. Remove contaminants from the grease zerk and surrounding area.
4. Add proper type of lubricant. See the lubrication chart on Page 69 for types of lubricant.
5. Wipe off excess lubricant.
NOTE: It is very important to keep the lubricant clean.

M. Procedure for Lubricating Jacks
1. Disconnect and lock motors out of service.
2. Follow all safe bin entry procedures and wear all required personal protective equipment.
3. Lubricate the gears using the grease zerk at the top of the jack. Rotate the jack handle to
distribute the grease.
4. Lightly grease the inner tube of the jack using the same type of grease.
5. Apply a light weight oil to the handle unit at both sides of the tube.
6. Apply a light weight oil to the small hole at the upper end of the jack to lubricate the nut and
screw assembly.
N. Frequency of Lubrication
The tractor drive pillow block bearings and the end flange bearing, along with the casters, should be
lubricated after each use of the Series II Sweep. If possible, lubricate all the components at the
beginning of each season or after long term storage.
