BULKHEAD
B3)
Pre-tap the four holes in the rear of the bulkhead. Install a 4-40 X 5/8” cap head
screw in the rear center hole of the bulkhead. Put the screw in until the threads
are almost ready to emerge from the part. (Left photo) Then turn the bulkhead
upside down and place the two 3/8” threaded inserts in their holes. The hexes
face forward and fit in the molded hexes in the bulkhead. Note that half of the
hex is molded into the bulkhead and half into the chassis. Keep the bulkhead
upside down for instruction B4.
B4)
Turn the chassis upside down and mate the bulkhead to the chassis. Take care
that the threaded inserts remain in their hexes in the bulkhead and go into their
hexes in the chassis. This is a pain to do, but most likely you’ll only have to do it
once. When you’ve got it right, secure the bulkhead by finishing installation of
the 5/8” cap head from B3 above.
