Step 12e:
This step describes how to adjust Type 32 cables. Cable
adjustments are made with the large bulkhead nuts only. Smaller nuts
on the rod ends should not be moved. Adjustments are made to the
connected breakers in various OPEN and CLOSED conditions. Refer to
Figures 17-20.
Ensure all bulkhead fittings are still approximately centered on the
cable mounting brackets, allowing for adjustment room in either
direction.
Repeat Items 8 and 9 of Step 9 if any bulkhead fittings requires
centering.
Perform initial adjustments on driven (long rod) end of cable (refer to
Figure 15). As adjustments are made with the connected breakers
in different states of OPEN and CLOSED, make certain that gaps
between the swivel fittings and the nuts are as indicated in the
applicable figure (Figures 17-20). In addition, the lever plate should
not rotate except when the connected breakers are CLOSED. In that
case, the lever plate will rotate approximately 60 degrees clockwise.
Torque cable bulkhead nuts on both ends to 100 - 120 in.-lbs
(11 - 13 N•m) when proper clearance is attained on driven end.
