ABSTRACT:
A liveload assembly having a stack guide with a thread on the exterior side wall, a plurality of compressible belleville washers stacked inside the stack guide, and a retainer cap having a thread on an inner side wall for matingly engaging with the stack guide to hold the belleville washers in compression. The gland follower of a fluid flow apparatus is liveloaded by placing the liveload assembly over the bolt extending upwardly from the gland follower. A nut is threaded on the bolt to contact the stack of belleville washers and the retainer cap is unscrewed to a second position on the stack guide and fixed by turning a set screw through a bore in the cap and against the side of the stack guide. Compression of the gland follower is monitored by viewing the relative movement of the stack of belleville washers through a longitudinal slot in the side wall.
