| contd :- -3- Assume 50 lbs. load required at cross steering tube radius to counteract wobble. This is equivalent to 75 lbs. at shock damper ball end or internal pressure of 237 lbs/sq.in. . . Leak must be adjusted so that it sets up a back pressure of 237 lbs/sq.in. when the oil flow is 4.24 pts/min. through it. From test curves taken with various sizes of leak, the required dimension of the hole with compressor oil at 65°F is .048". Hs{Lord Ernest Hives - Chair}/W.A.Robotham. | ||
