In Reply to: WTK: correct tube for a military budd 1/2 ton wherl posted by DDD [172.68.141.43] on Thursday, November 29, 2018 at 08:25:05 :
According to the War Department's TM 31-200, Maintenance and Care of Pneumatic Tires and Rubber Treads issued 4/1/1943, the correct tube for the 1/2 ton trucks, is a tube with a "Hand Bendable" rubber covered valve stem. This stem is found on 7.50x16 tubes and is straight and can be bent using a "Bending Tool" before the tube is installed, or a block of wood and your hands after the tube is installed and aired to the proper pounds. Make sure it is the long stem tube you use.
If you bend it yourself, place a 3/4 x 1-1/2 block of wood against the stem to keep it in the straight position, and with your other hand, bend the stem towards the outside of the tire to the desired angle. You can only bend the stem one way. If you bend the stem back to correct the angle, it will break the stem via cracks, however you can continue to bend the stem to get the angle you want, usually 90 degrees.
I've done this several times and it works fine.
