Inner Door Assembly
The inner door hinges (NCWT0254) are bolted to the inner door frame weldment through tapped holes.
(See detail B in
Figure 10V .) Attach using 3/8" x 5/8" bolts (S-7185) and washer (S-248).
The 2 ring door requires eight (8) total latch bar holders (WD-6234) assembled to the inner door frame
weldment. Washers will be used to adjust the distance between the frame and the latch bar holder for the
best fit of the inner doors. Use 1/2" washers (S-2120) and 1/2" x 1-1/2" bolt (S-3728) to secure the latch
bar holders (WD-6234). (See detail A in
Figure 10V .)
The 2 ring door requires eight (8) total bearing pins (WD-6224) to be used. Attach the bearing pins to the
inner door weldment using 5/16" x 1-1/2" bolts (S-2741), washer (S-845) and flange nut (S-3611). The
bearing pins should be attached at the eight (8) slots in the inner face of the weldment as shown in
Figure 10V . Leave the bearing pins loose until inner doors have been mounted to ensure a better fit.
Tighten the bearing pins once the inner doors are attached.
