Fine Material Screw Washer Maintenance
How much grease should I use to lubricate the lower bearing assembly?
The amount of grease required to lubricate the lower bearing assembly depends on the size of the Fine Material Screw Washer. Grease should be added with a grease gun every eight hours. Consult the Installation, Operation and Maintenance Manual for further details.
How do I know when to replace the wear shoes?
The wear shoes should be replaced when the leading edge is worn near to exposing the spiral flights that are welded to the pipe shafts. A visual inspection of the wear shoes will determine whether or not they need replaced.
When should I replace the oil in the gear reducer?
The oil in the gear reducer should be changed every 2,000 hours.
