Abstract: An apparatus for use with a device including a wall surface, and a removable, rotatable shaft having thereon a reference point and a bearing assembly, the bearing assembly including a surface supported by the wall surface with a shim between the bearing assembly surface and the wall surface, and with a fixed distance between the wall surface and the reference point when the bearing assembly is axially loaded in the device, the apparatus being for measuring the required thickness of the shim without inserting the shaft into the device, and the apparatus comprising a mechanism for axially loading the bearing assembly with the shaft out of the device, and a gauge rod for measuring the existing distance between the bearing assembly surface and the reference point.

Abstract: A lifting assembly for connection to a member to be lifted and to a filter hoist to first do the lifting and then to a second hoist to then do the lifting. The assembly comprises a base plate adapted to be connected to the member, and a lifting plate mounted on the base plate for pivotal movement about a horizontal axis, the lifting plate having a first eyelet adapted to be connected to one of the hoists, and a second eyelet adapted to be connected to the other of the hoists.
