Eric Platford - Chief Quality Engineer} c. to FH. Mr.Hardy. RE. STEERING (GENERAL.) X4264 *V3441 We can now sum this up better than heretofore. As you know, many combinations of steering are possible. Several special ones together may give satisfaction whilst another group may also give satisfaction from another point of view. For instance irreversible steering as you are now testing it will not do with leaning pivots if combined with spring buffer or bent (elastic) longitudinal tube, but it may be right with vertical pivots or even with leaning pivots if combined with good geometry (radius rod) and straight rigid steering tube. I therefore want you to test these combinations. (1) The first is irreversible steering with vertical pivots and present combination, but the longitudinal tube having set-up springs giving ample pressure, and having ample clearance - .5". In this case steering wobbles ought not to exist because the pivots are vertical.(i.e. incorrect geometry.) (2) The second combination would be irreversible steering, correct geometry with radius rod, and straight rigid steering tube - no buffers or other flexibility. - This ought to be right with either vertical or leaning (1) | ||
