| contd :- -2- We have a number of experiments running with altered king pin angles and pivots with horizontal trail, but so far have found nothing that is so effective as simply lengthening the existing stub axles by .5". Tests with one front brake only in action and 1.75° out of centre point indicate that such a situation will not be dangerous. We have both lowered the steering ratio and reduced the front braking besides fitting axle control in the last two years, all of which alterations help us in this connection. It will be seen that we have slightly increased the inner ball bearing. If it were possible to knock this bearing out before undoing the nut retaining the lever it would be possible to use a std. box spanner. but as yet it is suggested that the bearing could be pushed off by means of this nut, in which case a special set spanner would be required. Information as to the application of central lubrication will follow later. DA.{Bernard Day - Chassis Design} | ||
