3. To remove a VL Reversing Stationary Contact, use a
9/16" socket and ratchet to loosen and remove the nuts
and flat washers from each of the contact studs. See
Figure 89.
4. Remove the VL reversing stationary contact from the
contact assembly panel. See Figure 90.
5. Install the new VL reversing stationary contact into
the mounting holes in the contact assembly board.
Make sure when installing the contact that the leading
tapered edge is positioned toward the reversing neutral
stationary contact. If the tapered edge is facing in the
wrong direction, the stationary VR contact is being
used. See Figure 90.
6. Place a flat washer and nut on each stud. Use a 9/16"
socket and ratchet to tighten the nuts on each contact
stud. Using a torque wrench tighten the nuts to a
torque of 80
–
90 in-lbs (9.0
–
10.2 Nm). See Figures 91.
7. Once the work has been completed, place the tap-
changer in the neutral position.
