Using proper safety procedures and wearing required Personal Protective Equipment
(PPE), remove breaker from compartment, and place it on a solid work surface in a welllit
location.
To uninstall the primary disconnects, remove the Adjusting nut from one of the long
bolts holding the primary disconnect assembly together
Carefully slide out the bolt while removing the flat washer, spring, upper retainer, bowtie
spacers, lower retainer, and fingers from the bottom of the assembly.
Do the same for the other assembly bolt and components.
Slide off the retainer clips.
Take off the main retainer from the stud.
Slide the main retainer over the stud.
Set a pair of bow-tie spacers into a pair of fingers, place a pressure plate retainer over
the spacers to hold them in position, and then turn the subassembly over. Hook them
into the main retainer.
Slide a long bolt through the hole in the retainer, between the finger, and then through
the clip and stud spacer.
Hold the bottom finger subassembly in place.
Place two fingers around the bolt from the top, hooking the fingers into the main
retainer. Then place a bow-tie spacer in each finger and hold them in position with a
pressure plate retainer.
Place a spring, bushing, and flat washer over the bolt, then secure with the Adjusting
nut.
Repeat Steps 7 through 13 for each set of fingers.
Adjust the nut to get a spacing of 0.865-0.895 inch for WPS-32/WPH-32/WPX-32/ WPS-
40/ WPX-40 with Double springs and 0.766—0.797 inch for WPS-50/WPX-50 between
the top of the upper retainer and the bottom of the flat washer.
Clean finger assemblies, if necessary, with a clean, lint-free rag and isopropyl alcohol or
acetone.

onto the switchgear stabs (See Figure 48/49, Step 2). This product is available in a 1-0z
tube, ABB Part #193A1751P1.
