Changing the Cabin Master Pressure Regulator on the first B-47 jet bomber I was crew chief on..S/N 51-2338 back in 1956. This unit is "buried" in a compartment below the floor level in the cockpit behind the co-pilot's seat. You have to lay on your stomach curled around the seat and work through an access hole about 12 X 14 inches and 16 inches deep. The regulator unit is secured to the pressure bulkhead by a dozen Phillips head capscrews in a circular pattern about 10 inches in diameter. You have to use a magnetic tool to remove and replace these capscrews because you cannot reach them at all with your hands. You loosen and tighten them with a socket Phillips screwdriver, 12 inch long 1/4inch drive extension and ratchet.

Thank God I was young and kinda skinny in those days, I doubt if I could do it now..(weigh about 60 lbs. more and can't see without glasses).

To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
