18.Grasp the spring and insert the top of it on the end of the retaining bolt that protrudes into the cabinet.

Note: With the top of the spring being held in place by the end of this bolt, compressing and positioning the bottom of the spring into its seat is much easier.

19.When the spring is installed, thread the retaining bolt by hand all the way down until it seats into the hole in the top of the vibrating filter and stops.

20.At this point, un-thread the retaining bolt approximately 11/2" turns and lock the jam nut down against the cabinet so the bolt holds this position (Figure 39).

Note: The clearance between the end of the bolt and its seat gives room for the filter to vibrate but not fall out of position.
