SERVICING
T M Swivel Joints can be serviced while still in place, in line. They are greased at the factory and require lubrication only every 500 hours of service, unless the joint is in constant rotation, or subjected to high temperatures when lubricating is required more often.

When lubricating, remove plug on the outside of the body, insert grease plug fitting and lubricate until grease fills ball races and extrudes through weep hole.

Provisions have been made for take-up on packing to compensate for packing wear. Eventually, worn packing will need to be replaced.
