It will be remembered that we have had criticisms of the existing jacking system because an owner cannot insert the jack on to the rear jack pad when the tyre has come off the rim. In order to overcome this state of affairs the height of the rear jack pad on Loc.4973/4982 was raised. Unfortunately the position on the car now is that though the previous trouble is catered for, the wheel cannot now be removed as the jack does not lift the axle high enough. In other words, the lift of the jack is insufficient to cater for the extreme conditions. We did not stop the pads going to France for this reason because the value of the test out there is to see if they get damaged by stones or become difficult to use through mud etc. collecting on them. We have however taken up the question of a jack with increased lift with the Dunlop Company, and shall shortly have one on test. Until therefore the new jack has been tried out and found to be satisfactory, and the jack pads adjusted to suit it if necessary, we shall not be able to standardise the arrangement as fitted on B-50-BN.{W.O. Bentley / Mr Barrington} If these pads successfully complete 15,000 miles it will not of course be necessary to do further road work on them before a Standardisation Sheet can be issued.
